Design and Implementation of Distributed Automated Test System about Violence in Public Places

According to the actual need, this paper firstly designs the security monitoring system based on distributed network video. Then it particularly describes the working principle and flow of video camera with functions of image analysis, and improves the violence testing system in public places. Finally, violence is judged according to the changes in the optical flow field and the aggregated state of moving objects. The experimental results show that the embedded system has good accuracy, real- time performance and high reliability for recognition
