摘要: 针对运动人体跟踪的部分遮挡问题,提出了一种基于描述符交互的跟踪方法。该算法将运动人体用头部、躯干和下肢等运动blob描述符进行表达;然后通过投影blob描述符,更新、验证运动人体。算法利用投影描述符,有目的地选择目标和源数据样本,大大降低了核密度估计的计算代价。实验结果表明该方法处理简单,能够跟踪多个非刚性运动人体,较好地处理了部分遮挡问题,计算代价较小。

Abstract: In order to deal with part occlusion,a description interaction based moving human tracking approach is put forward.Firstly human is modeled as moving blobs descriptions.Then moving human is updated and verified by projecting these descriptions.The descriptions are used for choosing source and target samples to reduce compute cost of kernel density estimation.Moving objects can be tracked simply and part occlusion can be done well.

Key words: object tracking, description interaction, part occlusion, IFGT
