| 摘 要： | 针对摄像机运动情况下的多目标跟踪问题,提出了基于粒子滤波的跟踪算法.在粒子滤波算法基础上,将二阶自回归过程作为系统状态转移模型,HSV颜色直方图作为观测模型,对视频中多个目标的位置、大小进行跟踪.实验结果表明,该算法能实时正确地跟踪多个目标,并对局部遮挡有较好的鲁棒性,也能在目标短暂消失导致跟踪失败后,在目标重新出现后及时捕获并继续进行跟踪.

| Abstract: | A tracking algorithm based on particle filter is proposed to deal with multi-target tracking in a camera motion situation.In the proposed algorithm,the position and scale of targets in the video are tracked by using a second-order auto-regressive process as the tran-sition model and an HSV histogram as the observation model.Experimental results show that the proposed algorithm can track multi-target correctly in real-time and is robust to the partial occlusion.In addition,it can recover from tracking failur... |
