-A correlation-based tracking algorithm based on kalman prediction and adaptive reference template is discussed.

The target state in the next fr a me can be predicted using kalman prediction which can reduce the search area of the target

detection， and meet the target tracking in real time. Adaptive template update strategy which can adjust the reference template

based on the changes of the tracking target is used to improve the stability of target tracking. The simulation results indicate

that the algorithm can quickly adjust the reference template according to the changes of the shape size and position and the

target is tracked stably and real-time. The target also can be tracked efficaciously， when it is occluded.
