An automatic human motion tracking algorithm based the connection between the improved Snake model and optical flow arithmetic is proposed. The initial contour most close to human body is acquired by corner detection arithmetic, which decreases the iterations and reduces the probability of converging at local extreme value of Snake model. Because the tracking with Snake model is unstable and often loses the object, the good feature points are chosen from the contour points in current frame for optical flow estimation. Then the result is chosen as the initial contour in next frame. Experimental results show that improved Snake model can be deformed to the actual human body contour, and the automatic and real-time human tracking is implemented.
