Since Mean-Shift algorithm has proposed,it is developed and applied widely.But the traditional algorithm is out of use to the target whose speed is rapid and size is changing.To solve the first problem,the algorithm which combines Kalman prediction and MS is proposed.But when the size of object is changing,due to unchangeable of the bandwidth,the error of the background leads to failure to object tarcking too.To sovle the above two problems,this paper proposes a new algorithm based on Kalman prediction and ...
