The Research Of Moving And Change Detection Algorithm In Intelligent Video Surveillance And Realization On System

With the application of video surveillance system widely, it's necessary to intelligentize surveillance system. This thesis brings forward an integrated design and solution of intelligent video surveillance system based on moving and change detection technologys, studys some key technologys of intelligent video surveillance system, and implement the archetypal system.The purpose of introducing moving and change detection technologys is to detect moving objects. By picking up moving objects, we can get the details of moving objects, and save the video and picture as the evidence of crime.This thesis brings forward a new algorithm of moving and change detection: The algorithm introduces partitioning method based on the frame difference algorithm with changeless image; decides limit range according to the character of gauss distributing of CCD noise; adds brightness adaptive adjustability and updating referenced image. Compared with other algorithm, it's more accurate and more credible.This thesis designs an integrated solution of intelligent video surveillance system based on the moving and change detection algorithm, and implements exercisable archetypal system. The algorithm in this dissertation is verified by experiments and gets good results.
