Abstract

The moving objectives detecting technology in video surveillance system was stu-died.On the base of analysis and comparison of several target detection algorithm,a way of using block processing method to establish the initial background model was proposed.The method had a good inhibitory effect on the noise in video sequences,and it can overcome the shortcomings of fuzzy and residual shadow caused by mean method;In order to meet the change of background,the three-frames differences method was used to find those pixels that had a significant difference,then these pixels were updated adaptively.Simulation experiment showed that,this method can be used in background subtraction algorithm.The moving targets can be detected rapidly,completely and accurately.
