Abstract: This paper proposes a video tracking system for moving vehicle based on region and several improved techniques of the system. The tracking quality based on region lies on the detecting results. A hybrid difference strategy is introduced to attain higher detecting quality than other methods. A stack searching and a discriminating rule are designed to optimize the vehicle recognition. Experimental results indicate the video tracking system is feasible and useful in application of intelligent transportation system.

Key words: tracking based on region, vehicle video tracking, hybrid difference, video incident detection
