多物体遮挡情况下的视觉跟踪算法

针对视频监控中多运动物体间的遮挡问题,提出一种结合全局特征匹配与局部特征匹配的目标跟踪算法.该算法采用基于直方图和基于分块的方法共同表达目标的灰度特征.遮挡发生前实时进行遮挡预判,遮挡时采用基于块分类的方法跟踪目标,遮挡结束后通过直方图匹配重新定位目标.实验结果表明了该方法的有效性和优越性.

Vision tracking algorithm under occlusion of multiple objects

To solve the occlusion problem of multiple moving objects in video surveillance,a target tracking algorithm based on combination of global feature matching and local feature matching is proposed. In this algorithm,the methods based on histogram and block segmentation are adopted to express gray features of the target. The occlusion is pre-judged before it happens. When there is occlusion,the gray features based on block segmentation are used to track target. After occlusion,the target is re-located by histg...
