Real-Time Detection of Movement in Prohibited Direction for Video Surveillance System

Abstract Video surveillance systems are well established tools for monitoring important areas and detecting abnormal situations. In places such as one way road or tunnel, airport arrival gate, subway entry gate etc. it is important to monitor the direction of movement and to detect those which are prohibited. If the event is detected in the same time when the situation happens, a fast reaction can fix the problem (turning on the red light to prevent cars from entering the tunnel, sending security force to stop and search the suspect etc.). In the article a working system which is able to detect movement in prohibited direction is presented. The algorithm proved a very good detection rate for tested movie sequences. By optimizing various aspects of the algorithm a real-time efficiency (30fps) for 640×480 resolution frames is achieved.
