| Abstract: | In CamShift algorithm,color information is used for tracking the moving target,which may lead to failed tracking if the speed of the target is too high or disturbance exists.Therefore,we proposed an algorithm combining Extended Kalman Filter(EFK) with CamShift algorithm for tracking moving target,in which EKF can predict the position and the velocity of the moving target.On the other hand,the weighted histogram is used to improve CamShift algorithm.The proposed tracking algorithm can effectively overcome th... |
