Object Tracking Algorithm Based on Camshift Algorithm Combinating with Difference in Frame

Object tracking algorithm based on Camshift algorithm which is combinating with difference in frame is put forward to quickly and exactly track movement object. Firstly, we confirm the movement region of object by difference in frame, and we again confirm centroid of movement region which is centered to initialize tracking curve. Secondly, the feature is abstracted in the region and the target is tracked by Camshift algorithm. The method overcomes shortcoming of artificial orientation and divergence problem for traditional Camshift during tracking. We prove the validity of the algorithm by experiment at last.
