Hand Gesture Recognition-Based Non-Touch Character Writing System on a Virtual Keyboard
Multimedia Tools and Applications
SCIE | Impact Factor: 2.1
Abstract
The non-touch system is a modern approach of computer-interface technology capable of revolutionizing human-computer interaction. The interface allows the user to input data and interact with a human, machine or robot in an uncontrolled environment, treatment or industrial life. However, it is challenging to input data into the machine and interact with man and machine with a variety of complexities such as cluttered environment, gesture tracking, and speed. There are many evolving systems, for example, aerial handwriting, sign language recognition, and finger alphabet recognition require substantial effort for all character learning and overhead processing, thence the accuracy of the classification is reduced. Therefore, this paper proposes a non-touch character writing system that allows users to interact and manage the on-screen virtual keyboards in a secure and healthy way by recognizing few hand gestures. We divide this work into two parts: a) hand gesture recognition; and b) gestural flick input using a virtual keyboard. A user-friendly keyboard interface is displayed on the monitor, which uses a flick input method. A deep learning method with CNN is used to extract the features of a gesture. To determine these features, color segmentation is used to detect the hand; color pixels can be obtained by extracting a particular HSV (hue, saturation, value) and applying threshold masking to the input image. Finally, a support vector machine is used to give a more accurate classification of the hand gestures. The user uses a gestural flick input system to perform non-touch character input and enters the character by viewing the virtual keyboard. The character input is executed based on the recognition of the user’s hand gestures. Character input is evaluated based on the average classification accuracy of hand gestures and character recognition, and the accuracy and speed of input. Then, the system is compared with the state-of-the-art algorithms. The experimental results show that the proposed system can recognize seven typical gesture functions and input characters with 97.93% accuracy, which demonstrate the superiority compared to the state-of-the-art algorithms.

Enhanced Human Activity Recognition Based on Smartphone Sensor Data Using Hybrid Feature Selection Model
Sensors
SCIE | Impact Factor: 3.03
Abstract
Human activity recognition (HAR) techniques are playing a significant role in monitoring the daily activities of human life such as elderly care, investigation activities, healthcare, sports, and smart homes. Smartphones incorporated with varieties of motion sensors like accelerometers and gyroscopes are widely used inertial sensors that can identify different physical conditions of human. In recent research, many works have been done regarding human activity recognition. Sensor data of smartphone produces high dimensional feature vectors for identifying human activities. However, all the vectors are not contributing equally for identification process. Including all feature vectors create a phenomenon known as ‘curse of dimensionality’. This research has proposed a hybrid method feature selection process, which includes a filter and wrapper method. The process uses a sequential floating forward search (SFFS) to extract desired features for better activity recognition. Features are then fed to a multiclass support vector machine (SVM) to create nonlinear classifiers by adopting the kernel trick for training and testing purpose. We validated our model with a benchmark dataset. Our proposed system works efficiently with limited hardware resource and provides satisfactory activity identification.

Demographic Factors of Cybersecurity Awareness in Bangladesh
2019 5th International Conference on Advances in Electrical Engineering (ICAEE), Dhaka, Bangladesh, 26-28 Sept. 2019
Abstract
The growing rate of cybercrime has turned into a crucial concern that makes people more afraid of cyberwar than a nuclear weapon and climate change. An alarming awareness level has been observed in this study which is not satisfactory. A significant percentage of the population is unaware of cybersecurity policies and practices. Even the relevant organizations, as well as the government, are not concerned about the issues of cybercrime. A significant variation is essential to enrich the cybersecurity policies and practices. Furthermore, it needs to be monitored and restructured with the pace of time. This pilot study is designed to consider a comprehensive investigation regarding the level of cybercrime awareness amongst Bangladeshi people. The survey has been carried out through both the online and offline responses against a wellprepared questionnaire. Additionally, T-test, mean score and ANOVA tests were accompanied for detailed analysis. Based on this study, it is recommended that the development and implementation of a massive cybersecurity awareness program are urgently required that would immune the citizens from cyber threats.

A Novel Dynamic Hand Gesture and Movement Trajectory Recognition model for Non-Touch HRI Interface
2019 IEEE Eurasia Conference on IOT, Communication and Engineering (IEEE ECICE 2019), 3-6 Oct. 2019 Taiwan
Abstract
Efficient Human Robot Interaction (HRI) interface is very much demandable for controlling the semi-autonomous robots. Hand gesture recognition is an effective form of non-touch instruction. Thus, human hand gesture recognition is mostly used technique for HRI. However, in most research, some sensor devices or marker are incorporate with the hand or a large number of hand image and hand gesture sequence is stored and process for gesture recognition in machine learning techniques, which are costly and demand complex computation. From this point of view, an efficient dynamic hand gesture and movement trajectory recognition system is proposed in this paper, which can be used in real-time fashion for effective HRI interface. In the proposed dynamic gesture recognition system, hand images and skeleton information are extracted for Kinect sensor. Hands are segmented from the video frame using a skin color segmentation model from the region of interest (ROI) around the palm position of both hands. The hand open and close states are identified by calculating the position of palm and extreme position of Figure for activating the instruction recognition. The trajectory of segmented hands and the hands open state are considered for formulating the model of gesture with respect to the selected index points of body skeleton. Finally, several gesture models are derived to recognize the instruction during temporal gesture movement. For validating the proposed model, an experimental environment is setup in experimental lab. Ten volunteers are considered and tested the proposed system for six gesture instructions. According to the experiment, the proposed system shows 94.5% average recognition accuracy for dynamic motion instruction identification.

Smartphone Sensor Based Physical Activity Identification by Using Hardware-Efficient Support Vector Machines for Multiclass Classification
2019 IEEE Eurasia Conference on IOT, Communication and Engineering (IEEE ECICE 2019), 3-6 Oct. 2019 Taiwan
Abstract
Smartphone sensor-based activity identification has been recently received significant attention in versatile applications such as elderly people physical condition monitoring, general health monitoring, disease likelihood and other vital contexts to make human life more productive, secure and sound. Due to sensor derived data popularity, along with smartphone researchers are using other ad-hoc wearable devices like smartwatch, fitness tracker, fitbit for activity data collection. This paper emphasizes on heterogeneous optimal feature selection process based on Sequential Floating Forward Search (SFFS) approach. At the first stage, prominent discriminant features are elected from both time and frequency domain signal in order to create a robust model with better accuracy and generalization capability. Then the prime features are trained by Multiclass Support Vector Machines (SVMs) to identify twelve human activities by analyzing accelerometer-gyroscope sensory data taken from a published dataset. In this paper, SVM is applied to create nonlinear classifiers by adopting the kernel trick. Lastly, we have validated our model with online based benchmark dataset. Our proposed system works efficiently with limited hardware resource and provides satisfactory activity identification with trivial time duration as opposed to neural network.

Gestural Flick Input-Based Nontouch Interface for Character Input
The Visual Computer (TVCJ)
SCIE | Impact Factor: 1.415
Abstract
A non-touch character input is a modern system for communication between humans and computers that can help the user to interact with a computer, a machine, or a robot in unavoidable circumstances or industrial life. There have been many studies in the field of touch and non-touch character input systems (i.e., hand gesture languages), such as aerial handwriting, sign languages, and the finger alphabet. However, many previously developed systems require substantial effort in terms of learning and overhead processing for character recognition. To address this issue, this paper proposes a gesture flick input system that offers a quick and easy input method using a hygienic and safe non-touch character input system. In the proposed model, the position and state of the hands (i.e., open or closed) are recognized to enable flick input and to relocate and resize the on-screen virtual keyboard for the user. In addition, this system recognizes hand gestures that perform certain motion functions, such as delete, add a space, insert a new line, and select language, an approach which reduces the need for recognition of a large number of overhead gestures for the characters. To reduce the image-processing overhead and eliminate the surrounding noise and light effects, body index skeleton information from the Kinect sensor is used. The proposed system is evaluated based on the following factors: (a) character selection, recognition and speed of character input (in Japanese hiragana, English, and numerals); and (b) accuracy of gestures for the motion functions. The system is then compared to state-of-the-art algorithms. A questionnaire survey was also conducted to measure the user acceptance and usability of this system. The experimental results show that the average recognition rates for characters and motion functions were 98.61% and 97.5%, respectively, thus demonstrating the superiority of the proposed model compared to the state-of-the-art algorithms.

Non-Touch Sign Word Recognition Based on Dynamic Hand Gesture Using Hybrid Segmentation and CNN Feature Fusion
Applied Science, 2019, 9(18), 3790
SCIE | Impact Factor: 2.217
Abstract
Hand gesture-based sign language recognition is a prosperous application of human– computer interaction (HCI), where the deaf community, hard of hearing, and deaf family members communicate with the help of a computer device. To help the deaf community, this paper presents a non-touch sign word recognition system that translates the gesture of a sign word into text. However, the uncontrolled environment, perspective light diversity, and partial occlusion may greatly affect the reliability of hand gesture recognition. From this point of view, a hybrid segmentation technique including YCbCr and SkinMask segmentation is developed to identify the hand and extract the feature using the feature fusion of the convolutional neural network (CNN). YCbCr performs image conversion, binarization, erosion, and eventually filling the hole to obtain the segmented images. SkinMask images are obtained by matching the color of the hand. Finally, a multiclass SVM classifier is used to classify the hand gestures of a sign word. As a result, the sign of twenty common words is evaluated in real time, and the test results confirm that this system can not only obtain better-segmented images but also has a higher recognition rate than the conventional ones

Genetic Algorithm Based Optimal Feature Selection Extracted by Time-Frequency Analysis for Enhanced Sleep Disorder Diagnosis Using EEG Signal
Intelligent Systems Conference (IntelliSys), Advances in Intelligent Systems and Computing, vol. 1038, pp. 881-894 2019, London
SCOPUS
Abstract
Sleep disorders have a significant effect on psychological depression and many other human diseases. Nowadays, technology, as well as innovation, has become an essential and analytical part of the world. Detection of sleep disorders by brain waves has become a dynamic study. From this point of view, this paper proposed a model for detecting sleep disorders using time-frequency analysis based feature extraction model based on EEG (Electroencephalogram) signal. In this proposed method, Empirical mode decomposition (EMD) and wavelet packet transform (WPT) time-frequency analysis techniques are used for extracting effective features, because those techniques are very effective for analyzing the non-stationary signal like EEG. In this research, the EMD and WPT are used to decompose the input signal. In EMD decomposition, up to 9th IMFs (Intrinsic Mode Functions) are decomposed. In WPT decomposition, the EEG signal is decomposed up to third level wavelet coefficient. After the decomposition process, different statistical features are extracted, i.e., Shannon entropy, energy, standard deviation, skewness, and kurtosis. However, identifying the optimal sub-band of time-frequency analysis is very challenging. Thus, the genetic algorithm (GA) is used to select the effective subset of the feature. In the detection process, SVM classifier is used and sleep disorders are classified based on trained knowledge. As a result, the performance of the proposed method is evaluated for various statistical features and to find the optimal features for detecting sleep disorder. According to the experimental results, the proposed model shows improved performance by 4.88% improved classification accuracy.

Detecting and Learning Unknown Fault States by Automatically Finding the Optimal Number of Clusters for Online Bearing Fault Diagnosis
Applied Science 2019, 9(11), 2326
SCIE | Impact Factor: 2.217
Abstract
This paper proposes an online fault diagnosis system for bearings that detect emerging fault modes and then updates the diagnostic system knowledge (DSK) to incorporate information about the newly detected fault modes. New fault modes are detected using k-means clustering along with a new cluster evaluation method, i.e., multivariate probability density function’s cluster distribution factor (MPDFCDF). In this proposed model, a heterogeneous pool of features is constructed from the signal. A hybrid feature selection model is adopted for selecting optimal feature for learning the model with existing fault mode. The proposed online fault diagnosis system detects new fault modes from unknown signals using k-means clustering with the help of proposed MPDFCDF cluster evaluation method. The DSK is updated whenever new fault modes are detected and updated DSK is used to classify faults using the k-nearest neighbor (k-NN) classifier. The proposed model is evaluated using acoustic emission signals acquired from low-speed rolling element bearings with different fault modes and severities under different rotational speeds. Experimental results present that the MPDFCDF cluster evaluation method can detect the optimal number of fault clusters, and the proposed online diagnosis model can detect newly emerged faults and update the DSK effectively, which improves the diagnosis performance in terms of the average classification performance

Arm Movement Activity Based User Authentication in P2P Systems
Peer-to-Peer Networking and Applications (Accepted)
SCIE | Impact Factor: 2.239
Abstract
User authentication has become an essential security element that enables a wide range of applications in P2P systems for higher security and safety requirements. In previous, many researchers worked on user authentication based on certificates, passwords, and feature-based authentication (e.g. face recognition, fingerprint detection, iris recognition, voice recognition). However, authentication using those technologies may fail because this information can be easily shared among users or synthesized. Also, there are several cyber and cryptography attacks. With the progress of the latest sensor technology, wearable as Microsoft Bands, Fitbit, and Garmin has provided for more information collecting opportunities. From those above point of views, this paper presents a novel user identification system based on the bio signal analysis of arm movement (3-axis accelerometer & 3-axis gyroscope) and electromyography (EMG) signal using Myo armband as a wearable user authentication system in P2P system that identifies users based on the bio-signal of movement of a person's arm. In this study, the gesture and EMG signals are obtained from the sensor and denoised using wavelet denoising algorithm. The denoised signals are analyzed using the envelope and cepstrum analysis for extracting the potential feature vector. Finally, the feature vector is used to train and identify a user using multi-class support vector machine (MC-SVM) with different kernel function for user authentication. For validating the proposed authentication model, signals are obtained from the arm movements, i.e., directions and hand gesture data using acceleration, gyroscope and EMG sensors of several subjects. According to the experimental results, the proposed model shows satisfactory performance. To evaluate the efficiency of the proposed systems, we measure and compare its classification accuracy with state-of-the-art algorithms. And the proposed algorithm outperforms with others.

Histogram alternation based digital image compression using base-2 coding
2018 Digital Image Computing: Techniques and Applications (DICTA), Canberra, Australia,
Abstract
The goal of data compression algorithms is to promote the storage and delivery of big images with excellent compression ratio and least distortion. As the number of internet user is growing day by day, the transfer of data is being another significant concern. The storage and the use of an uncompressed picture are very costly and time-consuming. There are many techniques such as Arithmetic coding, Run-length coding, Huffman coding, Shannon-Fano coding used to compress an image. Compression of a picture using the state-of-the-art techniques has a high impact. However, The compression ratio and transfer speed do not satisfy the current demand. This article proposes a new histogram alternation based lossy image compression using Base-2 coding. It increases the probabilities of an image by doing a little bit of change to its pixels level which helps to reduce code-word. This algorithm uses less storage space and works at high-speed to encode and decode an image. Average code length, compression ratio, mean square error and pick signal to noise ratio are used to estimate this method. The proposed method demonstrates better performance than the state-of-theart techniques.

PCA and ICA Based Hybrid Dimension Reduction Model for Cardiac Arrhythmia Disease Diagnosis
IEEE 10th International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment, and Management, Baguio, Philippines
Abstract
Abstract—An arrhythmia is a fluctuation in the continuous beat of the heart (i.e., anomalous rhythm). Arrhythmia is considered a hazardous disease causing genuine medical problems in patients, when left untreated. For saving lives, early diagnosis of arrhythmias would be very conducive. The P-QRS-T wave of the Electrocardiogram (ECG) signal illustrates the cardiac function. However, it is a tough task to extract the discriminant information from a large number of data of ECG signal. In this perspective, this study exhibits a novel approach for diagnosing diseases related to cardiac arrhythmia. In this proposed model, a hybrid dimension reduction model including Independent and Principal Component Analysis (ICA, PCA) are introduced and machine learning features are extracted for disease diagnosis. The original ECG data are splitted into several windows and consider as input of dimension reduction process. After completing the ICA and PCA process, the different components of ICA and PCA are used for feature extraction. Finally, the Multi-Class Support Vector Machine (MCSVM) is used for training and identifying the disease. For evaluating the proposed method, MIT-BIH dataset is used. According to the experiment, the proposed model shows better classification accuracy using the first components of ICA and PCA algorithms, which is 98.67%.

Optimal IMF Selection of EMD for Sleep Disorder Diagnosis using EEG Signals
In The 3rd International Conference on Applications in Information Technology (ICAIT’18)
Abstract
Sleep disorders has a vital effect on mental depression and many other diseases of human body. Diagnosing the sleep disorder in an early curable stage may help to provide better treatment and save the life. The EEG (Electroencephalogram) signal is one of the most uses bio signal for capturing brain activities to detect and diagnosis the sleep disorders. Empirical mode decomposition (EMD) is an efficient time-frequency data analysis technique for diagnosing disease by analyzing EEG signal. However, it is a challenging issue to select the optimal intrinsic mode functions (IMFs) of Empirical mode decomposition (EMD) for extracting discriminant properties of EEG signals to diagnosis the sleep disorder. From this point of view, this paper presents a model to select optimal IMF of EMD for diagnosing the sleep disorder using EEG brain signal. In this proposed model, EMD is applied to decompose and analyze EEG signal for extracting biomarker/feature of sleep disorders. During the EMD decomposition process, different levels of IMF are extracted and features, i.e., Shannon Entropy, Spectral Entropy, Standard deviation, Skewness and Kurtosis are calculated from those IMFs for detecting the sleep disorders. In identification process, the multiclass support vector machine (MC-SVM) classification algorithm is used and sleep disorders are classified based on trained knowledge. Finally, the performance of proposed model is evaluated for different IMFs of EMD and find the optimal IMF for sleep disorder diagnosis. For evaluating the proposed model, a benchmark dataset including 4 types of data such as Apnea, REM, PLM and healthy subjects are used in experiment. According to the experimental result, the proposed model achieves the optimal classification performance for IMF 8, i.e., 93.24% average classification accuracy.

Human Machine Interaction based on Hand Gesture Recognition using Skeleton Information of Kinect Sensor
In The 3rd International Conference on Applications in Information Technology (ICAIT’18) (ACM), Aizu-Wakamatsu, Japan
Abstract
The hand gesture provides a natural and intuitive communication medium for the human and machine interaction. Because, it can use in virtual reality, language detection, computer games, and other human-computer or human-machine instruction applications. Currently, the sensor and camera-based application is a field of interest for many researchers. This paper proposes a new hand gesture recognition system using the Kinect sensor's skeleton data, which works in an environment where people do not touch devices or communicate verbally. The proposed model focuses on mainly two modules, namely, hand area and fingertip detection, and hand gesture recognition. The hand area and fingertip are detected by positioning the palm point and find extreme of contour. And, the hand gesture is recognized by measuring the distance between different body indexes of skeleton information. Here, six gestures instructions are considered such as move right to left, move left to right, move up to down, move down to up, open and closed, and also recognize the numeric number using the fingertip. This system is able to detect the presence of hand area and fingers and to recognize different hand gestures. As a result, the average recognition accuracy of different hand gestures and stretched fingers numbers are 95.91% and 96%, respectively.

Histogram modification based lossy image compression scheme using Huffman coding
4th International Conference on Electrical Engineering and Information & Communication Technology (iCEEiCT 2018)
Abstract
Medical images produce massive volumes of data, and consequently, suitable image compression procedures require to save expense and time of storage and transportation sequentially. The requirement of transferring or storing satellite images is increasing quickly with the evolution of advanced communications and imaging systems. In the digital world, the size of pictures is a major problem when dealing with the storage and transportation necessities. Compression is one of the most primary procedures to address this difficulty. The intention of data compression is to promote the storage and delivery of big images with excellent compression ratio and least distortion. Moreover, the number of internet user is growing day by day speedily. So, transferring of data is being an another significant concern. This article introduces histogram modification based lossy image compression using Huffman coding. A little bit change of pixel’s value is done which is why the number of probabilities of an original image is decreased and the value of probabilities are increased. As a result, Huffman coding uses very few bits in case of encoding and decoding than that of previous. This process provides higher compression ratio and less average code length keeping the same quality of the corresponding original image. Keywords: Lossy compression, Lossless compression, Huffman Coding, PSNR, Compression ratio, SVD coding.

Abstract
Advanced imaging technology produces a vast amount of data, particularly from the computed tomography modality. Store the imaging data and/or transfer the data through internet is a significant challenge in terms of cost and time. From this point of view, it is obligatory to compress the imaging data effectively. There are many state of the art coding techniques used to compress data such as Huffman coding. This paper proposes a new coding technique for loss-less imaging data compression. In this proposed method, the probability of image data has been assigned by binary sequence with fewer number of bits which provides an improved result than the state of art techniques in terms of compression ratio and average code length.

Texture Analysis Based Feature Extraction Using Gabor Filter and SVD for Reliable Fault diagnosis of an Induction Motor
International Journal of Information Technology and Management
SCOPUS
Abstract
This paper presents a texture analysis based feature extraction method using a Gabor filter and singular value decomposition (SVD) for reliable fault diagnosis of an induction motor. This method first converts one-dimensional (1D) vibration signal to a two-dimensional (2D) grey-level texture image for each fault signal. Then, the 2D Gabor filter with optimal frequency and orientation values is used to extract a filtered image with distinctive texture information, and SVD is utilised to decompose the Gabor filtered image and select finer singular values of SVD as discriminative features for multi-fault diagnosis. Finally, one-against-all multiclass support vector machines (OAA-MCSVMs) are used as classifiers. In this study, multiple induction motor faults with different noisy conditions are used to validate the proposed fault diagnosis methodology. The experimental results indicate that the proposed method achieves an average classification accuracy of 99.86% and outperforms conventional fault diagnosis algorithms in the fault classification accuracy.

A video-based smoke detection using smoke flow pattern and spatial-temporal energy analyses for alarm systems
Information Sciences, Volumes 418-419, Pages 91-101, ISSN 0020-0255.
SCI | Impact Factor: 4.832
Abstract
Detecting smoke during the initial stages is vital for preventing fire events. This study proposes a video-based approach for alarm systems that detects smoke based on temporal features extracted from optical smoke flow pattern analysis and spatial-temporal energy analysis. To do this, it considers various optical characteristics such as the diffusion, color, and semi-transparency of smoke. In the proposed model, smoke-colored pixels are identified via masking in the HSV color space and a temporal frame difference is applied. To extract the temporal feature vectors, we propose a new method that determines the optical flow of smoke by using distinguished texture information by applying a Gabor filter bank with preferred orientations. In addition, when applied to an image that has been temporal-differenced, the energy of the spatial frequencies is fed as another feature into the feature vector. Finally, these features are fed to a support vector machine (SVM) to discriminate our data more thoroughly and provide accurate detection of smoke. Experiments are carried out with benchmark datasets, which show that the proposed approach can work effectively without false alarms.

Reduction of Gesture Feature Dimension for Improving the Hand Gesture Recognition Performance of Numerical Sign Language
20th International Conference On Computer and Information Technology (ICCIT 2017)
Abstract
A major form of non-touch human-computer interaction (HCI) is hand gesture recognition. This is one of the appealing ways to interact with computers and a natural part of how we communicate. However, as a part of HCI, human hand gesture recognition is a challenging issue. From this point of view, this paper presents an effective hand gesture recognition system with hand feature selection for low cost video acquisition device. In this proposed model, hand features are extracted from video frame using discrete wavelet transformation and singular value decomposition. A genetic algorithm with effective fitness function is used to select optimal hand features by eliminating redundant and irrelevant features for improving the recognition performance. Finally, support vector machine is used to recognize the hand gestures for numerical hand gesture accuracy of American Sign Language. The proposed model is validated using a constructed hand gesture dataset. The proposed model is compared with non-feature selection based models, where the feature selection-embedded model outperforms the traditional hand recognition process.

Faster Convergence and Reduction of Overfitting in Numerical Hand Sign Recognition using DCNN
5th IEEE Region 10 Humanitarian Technology conference 2017
Abstract
Hand signs and signals are the staple form of expression for the hearing and speech impaired people. Human Computer Interaction technology enable people to interact with computer machine using hand gestures. Common sign languages use separate hand signals to communicate different decimals. Recent developments in Deep Convolutional Neural Networks (DCNN) have opened the door to recognize and classify this visual form of gestures more accurately. In this paper, a layer-wise optimized neural network architecture is proposed where batch normalization contributes to faster convergence of training, and introduction of dropout technique mitigates data overfitting. Batch normalization forces each training batch toward zero mean and unit variance, leading to improved flow of gradients through the model and convergence in shorter time. Dropout forces neurons of neural network to regularize, resulting in reduced overfitting. A constructed numerical hand gesture data set is used for validating the claims based on American Sign Language system. The proposed model is shown to surpass other methods in classifying these numerical hand signs successfully.

2017 International Conference on Networking, Systems and Security (NSysS 2017), Dhaka, Bangladesh
Abstract
The relationship between nurse and patient is vital as well as vulnerable on which a significant portion of well-being of patient depends. The recent growth of Internet of Things provides the opportunity to maintain this relationship in a more secure and efficient way. From this point of view, this paper presents a system of real-time nurse calling with focus centered on nurse feedback based on patient condition. The system also includes a robust archive monitoring system for review and trend analysis. In the proposed system, patients are able to call for assistance in time of emergency by pressing a designated button. After this, the device will send a real-time message containing information about the patients bed, room, and floor number to the appropriate nurse station. Nurse will respond as soon as the message is delivered, and optionally call for help by pressing designated buttons in the device. The proposed system reduces the delay in response of nurse. Additionally, the interactions are stored in Raspberry Pi database for future analysis to improve the quality of services. The proposed system uses low-cost hardware like ATMEGA328P microcontroller and ENC28J60 Ethernet controller, and Arduino Uno.

Abstract
YouTube is one of the comprehensive video information source on the web where video is uploading continuously in real time. It is one of the most popular site in social media, where users interact with sharing, commenting and rating (like/views) videos. Generally the quality, relevancy and popularity of the video is maintained based on this rating. Sometimes irrelevant and low quality videos ranked higher in the search result due to the number of views or likes, which seems untenable. To minimize this issue, we present a Natural Language processing (NLP) based sentiment analysis approach on user comments. This analysis helps to find out the most relevant and popular video of YouTube according to the search. The effectiveness of the proposed scheme has been proved by a data driven experiment in terms of accuracy of finding relevant, popular and high quality video.

Genetic Algorithm Based Discriminant Feature Selection for Improved Fault Diagnosis of Induction Motor
The 19th Int. Conf on Artificial Intelligence ICAI-17 (CSREA Press), Las Vegas, Nevada, USA
Abstract
In this paper, we present an efficient model for reliable fault diagnosis of the induction motor. This is now a growing demand for high classification accuracy in fault diagnosis. However, the system performance is highly dependable on superior feature analysis. But, it’s still crucial and computational complex to select discernment features, thus, a new genetic algorithm (GA) with optimum class separability criteria is utilized to find most discriminate features from a hybrid feature vector. For this approach, wavelet packet decomposition (WPD) is applied on Acoustic Emission (AE) fault signal and hybrid statistical features are extracted from a decomposed wavelet packet coefficient, which has maximum energy. GA and Euclidean distance based novel, optimum class separability (OCS) are used to select the optimal low-dimensional feature set from high dimensional feature set. The efficacy of this proposed model, in terms of classification accuracy, is validated by the knearest neighbor (k-NN) classifier. Experimental results show that the proposed model has a superior classification, yielding an average classification accuracy above 98%.

Efficient Bearing Fault Diagnosis by Extracting Intrinsic Fault Information using Envelope Power Spectrum
2017 IEEE International Conference on Imaging, Vision &Pattern Recognition , Dhaka
Abstract
Early and efficient fault diagnosis of bearing of industrial motor is a modern demand for reducing unexpected breakdown of industrial process. Extracting the intrinsic fault signature in very early stage is important. In this point of view, this paper proposes a fault diagnosis model of industrial bearing including efficient fault signature extraction technique based on narrow band frequency domain analysis of acoustic emission (AE) signal using envelope power spectrum. To do that, AE signals are collected from defective and non-defective bearings under different rotational speeds from industrial-like experimental environment. Envelope power spectrum is calculated from the AE signal and narrow band root mean square (NBRMS) fault features are extracted from defect frequency ranges of the envelope power spectrum. Finally, the k-nearest neighbor (k-NN) classification algorithm is used for identifying the fault of unknown signal and validating the efficiency of the proposed feature extraction model. The experimental result shows that the proposed model outperforms state-of-art algorithms in terms of classification accuracy.

Abstract
This paper proposes a hybrid feature selection scheme for identifying the most discriminant fault signatures using an improved class separability criteria—the local compactness and global separability (LCGS)—of distribution in feature dimension to diagnose bearing faults. The hybrid model consists of filter based selection and wrapper based selection. In the filter phase, a sequential forward floating selection (SFFS) algorithm is employed to yield a series of suboptimal feature subset candidates using LCGS based feature subset evaluation metric. In the wrapper phase, the most discriminant feature subset is then selected from suboptimal feature subsets based on maximum average classification accuracy estimation of support vector machine (SVM) classifier using them. The effectiveness of the proposed hybrid feature selection method is verified with fault diagnosis application for low speed rolling element bearings under various conditions. Experimental results indicate that the proposed method outperforms the state-of-the-art algorithm when selecting the most discriminate fault feature subset, yielding 1.4% to 17.74% diagnostic performance improvement in average classification accuracy.

Reliable Fault Diagnosis of Bearings Using Distance and Density Similarity on an Enhanced k-NN
Artificial Life and Computational Intelligence,Volume 10142 of the series Lecture Notes in Computer Science (LNCS) pp 193-203
LNCS
Abstract
The k-nearest neighbor (k-NN) method is a simple and highly effective classifier, but the classification accuracy of k-NN is degraded and becomes highly sensitive to the neighborhood size k in multi-classification problems, where the density of data samples varies across different classes. This is mainly due to the method using only a distance-based measure of similarity between different samples. In this paper, we propose a density-weighted distance similarity metric, which considers the relative densities of samples in addition to the distances between samples to improve the classification accuracy of standard k-NN. The performance of the proposed k-NN approach is not affected by the neighborhood size k. Experimental results show that the proposed approach yields better classification accuracy than traditional k-NN for fault diagnosis of rolling element bearings.

Abstract
Increased accuracy in predictive models for handwritten character recognition will open up new frontiers for optical character recognition. Major drawbacks of predictive machine learning models are headed by the elongated training time taken by some models, and the requirement that training and test data be in the same feature space and consist of the same distribution. In this study, these obstacles are minimized by presenting a model for transferring knowledge from one task to another. This model is presented for the recognition of handwritten numerals in Indic languages. The model utilizes convolutional neural networks with backpropagation for error reduction and dropout for data overfitting. The output performance of the proposed neural network is shown to have closely matched other state-of-the-art methods using only a fraction of time used by the state-of-the-arts.

Abstract
Reliable and ef cient fault diagnosis of induction motors is an important issue in industrial environments. This paper proposes a method for reli- able fault diagnosis of induction motors using signal processing of acous- tic emission (AE) data, including Gabor ltering and the use of multiclass support vector machines (MCSVMs), where a ZigBee based wireless sensor network (WSN) model is used for ef ciently transmitting AE sig- nals to a diagnosis server. In the proposed fault diagnosis approach, the induction motor’s different state signals are acquired through proper placement of AE sensors. The AE data are sent to a server through the wireless sensor network and decomposed using discrete wavelet transfor- mation (DWT). An appropriate band is then selected using the maximum energy ratio, and a one-dimensional (1D) Gabor lter with various fre- quencies and orientation angles is applied to reduce abnormalities and extract various statistical parameters for generating features. In addition, principal component analysis (PCA) is applied to the extracted features to select the most dominant feature dimensions. Finally, one-against-one multiclass support vector machines (OAA-MCSVMs) are used to classify multiple fault types of an induction motor, where each SVM individually trains with its own features to increase the fault classi cation accuracy of the induction motor. In experiments, the proposed approach achieved an average classi cation accuracy of 99.80%, outperforming conventional fault diagnosis models.

Abstract
Features selection (FS) techniques have an apparent need in many complex engineering applications especially the bearing fault diagnosis of low-speed industrial motor. The main goal of an FS algorithm is to select the most discriminant features subset from a high-dimension features vector that increases the model performance by reducing the redundant and irrelevant fault features. This paper proposes an efficient fault diagnosis model of bearing by incorporating the optimal feature selection approach for increasing the reliability of fault diagnosis of bearing. Also, this paper investigates the feature selection approaches including sequential forward selection (SFS), sequential floating forward selection (SFFS), and genetic algorithm (GA) for identifying the most discriminant subset. The effectiveness of this discriminant features subset is verified with a low-speed bearing fault diagnosis application for identifying bearing failures. The experimental shows up-to-mark diagnosis performance using GA based optimal feature selection method.

Distance and Density Similarity Based Enhanced k-NN Classifier for Improving Fault Diagnosis Performance of Bearings

SCIE | Impact Factor: 1.857
Abstract
An enhanced -nearest neighbor (-NN) classification algorithm is presented, which uses a density based similarity measure in addition to a distance based similarity measure to improve the diagnostic performance in bearing fault diagnosis. Due to its use of distance based similarity measure alone, the classification accuracy of traditional -NN deteriorates in case of overlapping samples and outliers and is highly susceptible to the neighborhood size, . This study addresses these limitations by proposing the use of both distance and density based measures of similarity between training and test samples. The proposed -NN classifier is used to enhance the diagnostic performance of a bearing fault diagnosis scheme, which classifies different fault conditions based upon hybrid feature vectors extracted from acoustic emission (AE) signals. Experimental results demonstrate that the proposed scheme, which uses the enhanced -NN classifier, yields better diagnostic performance and is more robust to variations in the neighborhood size, .

SCI | Impact Factor: 7.05
Abstract
In practice, outliers, defined as data points that are distant from the other agglomerated data points in the same class, can seriously degrade diagnostic performance. To reduce diagnostic performance deterioration caused by outliers in data-driven diagnostics, an outlier-insensitive hybrid feature selection (OIHFS) methodology is developed to assess feature subset quality. In addition, a new feature evaluation metric is created as the ratio of the intraclass compactness to the interclass separability estimated by understanding the relationship between data points and outliers. The efficacy of the developed methodology is verified with a fault diagnosis application by identifying defect-free and defective rolling element bearings under various conditions.

A Two Dimensional Fault Diagnosis Model of Induction Motors using Gabor Filter on Segmented Images

Abstract
Image segmentation has received extensive attention due to the use of high-level descriptions of image content. This paper proposes a fault diagnosis model using a Gabor filter on segmented two-dimensional (2D) gray-level images. The proposed approach first converts time domain AE signals into 2D gray-level images to exploit texture information from the converted images. 2D discrete wavelet transform (DWT) is then applied to select appropriate (vertical) texture information and reconstructed it into an image. The reconstructed image is segmented into a number of sub-images depending on the segment size and a Gabor filter is applied on each sub-image. Finally, feature vectors are extracted from the Gabor-filtered sub-images and utilized as inputs in a one-against-all multiclass support vector (OAA-MCSVM) to identify each fault in an induction motor. In this study, multiple bearing defects under various segment sizes are utilized to validate the effectiveness of the proposed method. Experimental results indicate that the proposed model outperforms conventional Gabor-filter-based 2D fault diagnosis algorithms in classification accuracy, exhibiting a 97 % average classification accuracy for 64×64 segmented images.

Discriminant feature distribution analysis-based hybrid feature selection for online bearing fault diagnosis in induction motors
Journal of Sensors
SCIE | Impact Factor: 2.057
Abstract
Optimal feature distribution and feature selection are of paramount importance for reliable fault diagnosis in induction motors. This paper proposes a hybrid feature selection model with a novel discriminant feature distribution analysis-based feature evaluation method. The hybrid feature selection employs a genetic algorithm- (GA-) based filter analysis to select optimal features and a -NN average classification accuracy-based wrapper analysis approach that selects the most optimal features. The proposed feature selection model is applied through an offline process, where a high-dimensional hybrid feature vector is extracted from acquired acoustic emission (AE) signals, which represents a discriminative fault signature. The feature selection determines the optimal features for different types and sizes of single and combined bearing faults under different speed conditions. The effectiveness of the proposed feature selection scheme is verified through an online process that diagnoses faults in an unknown AE fault signal by extracting only the selected features and using the -NN classification algorithm to classify the fault condition manifested in the unknown signal. The classification performance of the proposed approach is compared with those of existing state-of-the-art average distance-based approaches. Our experimental results indicate that the proposed approach outperforms the existing methods with regard to classification accuracy.

First, a set of statistical, time-domain, and frequency domain features are extraction from AE signal. Of these features, some features having more informative data to distinguish faults are selected. Finally, a classifier based on local outlier factor (LOF) is used to detect faults of bearing.

Abstract
This paper proposes a centroid global positioning system (GPS) model to improve the positioning accuracy of low-cost GPS receivers of a sensitive location-based system. The proposed model estimates the precise movement position by a centroid sum of the individual improved positions of three GPS receivers. Each GPS receiver’s position is improved by using a direction and velocity averaging technique based on combining the vehicle movement direction, velocity averaging, and distance between the waypoints of each GPS receiver using coordinate data (latitude, longitude, time, and velocity). Finally, the precise position is estimated by calculating a triangular centroid sum with distance threshold of the improved positions of three GPS receivers. In order to evaluate the performance of the proposed approach, we used three GARMIN GPS 19x HVS receivers attached to a car and plotted the processed data in Google map. The proposed approach resulted in an improved accuracy of about 2–12 m compared to the original GPS receivers. In addition, we compared the proposed approach to two other state-of-the-art methods. The experimental results show that the proposed approach outperforms the conventional methods in terms of positioning accuracy.

Maximum class separability-based discriminant feature selection using a GA for reliable fault diagnosis of induction motors
Lecture Notes in Artificial Intelligence LNAI
SCOPUS
Abstract
Reliable fault diagnosis in bearing elements of induction motors, with high classification performance, is of paramount importance for ensuring steady manufacturing. The performance of any fault diagnosis system largely depends on the selection of a feature vector that represents the most distinctive fault attributes. This paper proposes a maximum class separability (MCS) feature distribution analysis-based feature selection method using a genetic algorithm (GA). The MCS distribution analysis model analyzes and selects an optimal feature vector, which consists of the most distinguishing features from a high dimensional feature space, for reliable multi-fault diagnosis in bearings. The high dimensional feature space is an ensemble of hybrid statistical features calculated from time domain analysis, frequency domain analysis, and envelope spectrum analysis of the acoustic emission (AE) signal. The proposed maximum class separability-based objective function using the GA is used to select the optimal feature set. Finally, k-nearest neighbor (k-NN) algorithm is used to validate our proposed approach in terms of the classification performance. The experimental results validate the superior performance of our proposed model for different datasets under different motor rotational speeds as compared to conventional models that utilize (1) the original feature vector and (2) a state-of-the-art average distance-based feature selection method.

Sound synthesis is recently indispensable with sophisticated audio effects for mimicking rich and natural sounds of the musical instruments, and thus sound synthesis acceleration has been an urgent issue. The formant synthesis is employed to produce the various single notes of the haegeum, a representative traditional Korean bowed string instrument. In this study, the formant synthesis process using multiple pairs of digital resonators and band-pass filters is accelerated with the power of a general-purpose graphics processing unit (GPGPU). This paper compares the performance of the proposed GPGPU-based parallel approach with the CPU-based sequential approach in order to validate the effectiveness of the proposed massively parallel method. Experimental results indicate that the proposed parallel approach achieves at least 79 times speedup over the CPU-based approach by exploiting the massive parallelism inherent in the formant sound synthesis algorithm.

Abstract
This paper presents three texture feature extraction techniques: gray level co-occurrence matrix (GLCM), Gabor filter, and global neighborhood structure (GNS) map, for the fault diagnosis of induction motors. The texture of two- dimensional (2D) gray level images is converted from acoustic emission (AE) fault signals and used for feature extraction of the fault signals. The extracted texture features are used as inputs to a multi-class support vector machine (MCSVM) to classify each fault. The Gaussian radial basis function kernel is used with MCSVM to handle non-linear fault features of acoustic emission (AE) signals. Experimental results with one-second AE signals sampled at 1 MHz showed that the GLCM-based feature extraction method outperformed the Gabor filter and the GNS map in terms of classification accuracy because of its ability to capture the spatial dependence of gray-level texture values.

Abstract
Positioning accuracy is a challenging issue for location-based applications using a low-cost global positioning system (GPS). This paper presents an effective approach to improving the positioning accuracy of a low-cost GPS receiver for real-time navigation. The proposed method precisely estimates position by combining vehicle movement direction, velocity averaging, and distance between waypoints using coordinate data (latitude, longitude, time, and velocity) of the GPS receiver. The previously estimated precious reference point, coordinate translation, and invalid data check also improve accuracy. In order to evaluate the performance of the proposed method, we conducted an experiment using a GARMIN GPS 19xHVS receiver attached to a car and used Google Maps to plot the processed data. The proposed method achieved improvement of 4–10 meters in several experiments. In addition, we compared the proposed approach with two other state-of-the-art methods: recursive averaging and ARMA interpolation. The experimental results show that the proposed approach outperforms other state-of-the-art methods in terms of positioning accuracy.

International Conference on Informatics, Electronics & Vision (ICIEV)
Abstract
This paper proposes a reliable RGB color image watermarking which uses discrete wavelet transform (DWT) and singular value decomposition (SVD) for embedding and extracting watermark. The DWT and SVD applied on the watermark image increase information hiding capacity and perceptual similarity of the watermarked image. In the watermarking embedded stage, the processed watermark information using the proposed method is embedded into three color components (R, G and B) with an optimum watermarking scaling factor (α). In the extraction stage, the resultant watermark is calculated by averaging the three extracted watermarks from R, G and B components. The experimental results show that the proposed method achieves high normalized correlation (NC) of the extracted watermark and high peak signal to noise ratio (PSNR) of the watermarked image after several image processing attacks. In addition, the proposed method outperforms other conventional methods in terms of perceptual similarity, robustness, and detection rate.

This paper presents an effective approach to improving the positioning accuracy of a low-cost GPS receiver for real-time navigation. The proposed method precisely estimates position by combining vehicle movement direction, velocity averaging, and distance between waypoints using coordinate data (latitude, longitude, time, and velocity) of the GPS receiver. The previously estimated precious reference point, coordinate translation, and invalid data check also improve accuracy. In order to evaluate the performance of the proposed method, we conducted an experiment using a GARMIN GPS 19xHVS receiver attached to a car and used Google Maps to plot the processed data. The proposed method achieved improvement of 4–10 meters in several experiments. In addition, we compared the proposed approach with two other state-of-the-art methods: recursive averaging and ARMA interpolation. The experimental results show that the proposed approach outperforms other state-of-the-art methods in terms of positioning accuracy.

Spectral Modeling Synthesis of Haegeum Using GPU
Winter Conference of the Korea Society of Computer and Information No. 22, Issue 1, 2014
Abstract
This paper presents a parallel approach of formant synthesis method for haegeum on graphics processing units (GPU) using spectral modeling. Spectral modeling synthesis (SMS) is a technique that models time-varying spectra as a combination of sinusoids and a time-varying filtered noise component. A second-order digital resonator by the impulse-invariant transform (IIT) is applied to generate deterministic components and the results are band-pass filtered to adjust magnitude. The noise is calculated by first generating the sinusoids with formant synthesis, subtracting them from the original sound, and then removing some harmonics remained. The synthesized sounds are consequently by adding sinusoids, which are shown to be similar to the original Haegeum sounds. Furthermore, GPU accelerates the synthesis process enabling-real time music synthesis system development, supporting more sound effect, and multiple musical sound compositions.

Determination of the Traveling Speed of a Moving Object of a Video Using Background Extraction and Region Based Segmentation
International Journal of Computer Science and Information Security(IJCSIS)
Abstract
This paper is concerned with the determination of thetraveling speed of a moving object of a video clip based onsubsequent object detection techniques. After preprocessing of the original image sequence, which is sampled from the videocamera, the target moving object is detected with the improvedalgorithm in which the moving object region can be extractedcompletely through several processing of background extractionand region based segmentation such as region-connection, region-merging, and region-clustering methods. Among the multiplemoving objects of the video, the target object has been detectedbased on particular criteria of region that it occupies. Then theresults of these processing can be used to determine the travelingspeed of the target moving object from changes of its coordinateposition from the video frames. Among the different video fileformat, Audio Video Interleaved (AVI) format has been used toexamine our experiments

EMG Signal Decomposition Using Wavelet Transformation with Respect to Different Wavelet and a Comparative Study
2nd International Conference on Interaction Sciences: Information Technology, Culture and Human, Korea, ACM New York, NY, USA ©2009
Abstract
Electromyography (EMG) signals can be used for clinical/biomedical applications, Evolvable Hardware Chip (EHW) development and modern Human Computer Interaction. EMG signals acquired from muscles require advanced methods for detection, decomposition, processing, and classification. For properly analyze EMG signal there need good quality of decomposition so that it can reveal the total characteristics of EMG signals. Because EMG signal is Non-Stationary signal so it needs such a method that can decompose non-stationary signal thus wavelet decomposition is a good choice for this type. There are different types of wavelet available. Henceforth, it is necessary that proper attempt should be taken to choice the best one. Here analyses of EMG Signals were made by Various Wavelet Decomposition method with different types of wavelet and it illustrates the comparative study on best possible energy localization in the time-scale plane in order to show the performance. Thus we can choice the right one. The EMG signals used for this analysis - were found both from locally collected as well as from www.emglab.net[5] which provides EMG signal related raw data and other facilities.
