Research and implementation of intrusion detection algorithm in video surveillance

A video surveillance intrusion detection system is designed in this paper, the main function modules of the system include target detection, automatic identification and automatic alarm. When the user star the program, the system will call the camera and open video surveillance and automatic alarm system. The three frame difference method and background subtraction method are used to detect intrusion behavior. Experimental results show that the system is practical, easy to operate and has higher working efficiency which can reach the user's expected goal.
