Real-Time Video Surveillance System Using a Field programmable Gate Array

摘要

In this article, a stand-alone real-time video surveillance system is presented. This system monitors a scene through a fixed master camera with a wide field of view and then directs a slave camera to capture automatically high-resolution images of moving targets within the scene. Motion detection is achieved by means of background differencing using adaptive thresholding and a temporal filter to continually update the background. The user can set the system to respond to different types of targets on the basis of their size and shape.
