| 摘 要： | 在采用CamShift算法进行移动目标跟踪时,如果目标快速移动或者有遮挡物干扰时,仅利用移动的颜色信息对进行跟踪时容易导致跟踪失败。为了解决该问题,提出了移动目标运动估计和CamShift算法相结合的目标跟踪算法。通过结合削弱背景中含有的目标颜色直方图信息和进行移动目标的运动估计,从而在存在干扰目标或目标部分被遮挡的情况下,仍能实现有效跟踪。最后通过实验验证该算法的有效性。

| Abstract: | When target move fast or there were interference,the target tracking algorithm based on CamShift was often tracking failure only using color information.In order to solve this problem,an improved CamShift target tracking algorithm which combined with mobile target estimation was precented.By weakening color histogram information of the target in the background and estimating target motion,this algorithm still can realize effective tracking in the occlusion or interference of the tracked target.The validity of the algorithm is proved by experiment. |
