Abstract: In order to solve the problems made by manual operation in video tracking algorithm, such as, approval difficulties, low accuracy and tracking failure, a novel method to calibrate the initial center of position and extract the size of the salient moving target based on human vision is proposed in this paper. This method utilizes the characteristics of the images brightness and the motion vector in forward and backward frames, which can adaptively obtain the optimal center point and the region of target. With the simulation results, the parameters of the target are acquired accurately by the proposed method. The initial localization method which has good performance even when the background and the target are both moving or the difference between them are small.
