Systems for Video Detection and Tracking of Mobile Objects
RÉSUMÉ
Main techniques are considered for optimization of video camera operation and preliminary processing of images of mobile objects obtained under complicated conditions of video surveillance as well as the method of image synthesis of contrast objects. The results of morphological filtering application for improving the signal-to-noise ratio and obtaining contour preparations of objects are presented. The attributes allowing segmentation of objects at the complicated background, are provided. The methods of considering the motion of objects - optical flow and motion energy - are described. The algorithm for automatic defining of the motion detection threshold is suggested. The classification and comparison analysis of methods for tracking of mobile objects are given. The drawbacks of the methods based on correlation and motion energy are considered. The algorithm is suggested and the advantages of the method based on segmentation of objects into the motion layers are demonstrated.
