Paper Abstract

A surveillance system that detects and tracks security breaches in airports is presented. The system consists of two subsystems with one overhead static and one Pan/Tilt/Zoom (PTZ) camera to first acquire and then follow an intruder who illegally walks into a crowded secure area of an airport. The overhead camera detects the intruder using a motion-based segmentation and an optical flow algorithm. Intruder handover from the overhead camera to the PTZ camera is then performed. A novel approach for intruder handover and feature extraction using color is presented for continuous tracking with the PTZ camera when the intruder moves out of the view of the overhead camera. We also use a mean shift filter with a newly designed non-rectangular search window which will be automatically updated to accurately localize the target. Real experimental results from a local airport are given and discussed.
