In this chapter, the authors propose two algorithms based on the device of attributes for tracking of the abnormal behavior of crowd in the visual systems of surveillance. Previous works were realized in the case of detection of behavior, which uses the analysis and the classification of behavior of crowds; this work explores the continuity in the same domain, but in the case of the automatic tracking based on the techniques of filtering one using the KALMAN filter and particles filter. The proposed algorithms he the technique of filter with particle is independent from the detection and from the segmentation human, so is strong with regard to (compared with) the filter of Kalman. In conclusion, the chapter applies the method for tracking of the abnormal behavior to several videos and shows the promising results.

A many of researches have been carried out in the field of the crowd behavior recognition system. Recognizing crowd behavior in videos is most challenging and occlusions because of irregular human movement. This paper gives an overview of optical flow model along with the SVM (Support Vector Machine) classification model. This proposed approach evaluates sudden changes in motion of an event and classifies that event to a category: Normal and Abnormal.  Geometric means of location, direction, and displacement of the feature points of each frame are estimated. Harris corner Detector is used in each frame for tracking a set of feature points. Proposed approach is very effective in real time scenario like public places where security is most important. After analyzing result ROC curve (receiver operating characteristics) is plotted which gives classification accuracy. We also presented frame level comparison with Ground truth and social force model (SFM) techniques. Our proposed approach is giving a promising result compare to all state of art methods.

Classification of target from a mixture of multiple target information is quite challenging. In This paper we have used supervised Machine learning algorithm namely Linear Regression to classify the received data which is a mixture of target-return with the noise and clutter. Target state is estimated from the classified data using Kalman filter. Linear Kalman filter with constant velocity model is used in this paper. Minimum Mean Square Error (MMSE) analysis is used to measure the performance of the estimated track at various Signal to Noise Ratio (SNR) levels. The results state that the error is high for Low SNR, for High SNR the error is Low

The classification of sleep disorders is essential both for correct diagnosis and for coding purposes. There are three major sleep disorder classifications in the USA: the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V), the American Academy of Sleep Medicine’s International Classification of Sleep Disorders (ICSD-3), and the International Classification of Diseases Modified Version (ICD-10-CM). This chapter discusses these classifications and their differences. DSM-V and ICSD-3 are used mainly for diagnostic information, whereas ICD-10-CM is used for coding. Sleep disorders can be regarded as falling into three main groups: those that cause difficulty with nighttime sleep, those that cause daytime sleepiness, and those that cause abnormal behavior during the night. The disorders, such as insomnia disorder, narcolepsy, circadian rhythm sleep disorders, obstructive sleep apnea syndrome, and the parasomnias, in these three groups are organized differently, depending upon the classification system. The most detailed diagnostic classification system is ICSD-3, whereas the DSM-V classification is a simplified version, predominantly for psychiatrists.
