A Geometric Approach to Video Surveillance


Intrusion detection is one of the important functions for smart video surveillance. Presented in this paper is a geometric approach to intrusion detection. Our approach consists of a geometric flow and an image flow. Given a 3D global boundary for a wide area requiring multi-CCTVs, it is transformed into the 2D local boundary for each camera in the geometric flow. The bounding box for a moving one is computed in the image flow. Finally, whether one intrudes a guard zone can be decided by calculating their intersection. By experiments, we could find our approach is robust and adaptive in multiCCTVs environment where cameras are replaceable.
