An integrated system for automatic detection, handover and tracking of an intruder using one fixed camera and one Pan/Tilt/Zoom(PTZ) camera is presented. This system includes automatic detection using an overhead static camera of an intruder who walks into a crowded secure area, intruder handover from the static to the nearest PTZ camera, and tracking using the PTZ camera. The intruder is detected by applying optical flow algorithms to video from the overhead camera. A PTZ camera extracts the intruder detected by the overhead camera and builds a color histogram model of the target. A novel region segmentation based on the color histogram and the algorithm for tracking are presented with real experimental results.
