基于角点采样的多目标跟踪方法

为了跟踪互遮挡的多个目标,提出了一种基于角点采样的多目标跟踪方法。该方法以遮挡发生前的各目标区域中的Harris角点信息为样本,在遮挡发生情况下,采取K近邻分类器对目标区域中提取的角点信息进行分类,以有效区分遮挡在一起的多个目标。在角点特征提取过程中,还提出了双阈值Harris角点检测算法,用于自适应、准确地提取运动区域中角点信息。实验结果表明,该方法能有效区分遮挡在一起,且没有分裂之前的多个目标。

Tracking Multiple Objects Method Based on Harris Corner Sampling

To track multiple objects which were occluded each other,a multi-target tracking method based on the sampled corners was proposed,which extracted Harris corner information as the training sample before occluding and used K nearest neighborhood (KNN) classifier to classify the corners in the occluding region. And this method can effectively distinct multiple targets through occlusion. In the process of extracting corners,the dual-threshold Harris corner detection algorithm was proposed. It can adaptively and accurately extract corners. The experimental results show that the proposed method can effectively track multiple objects which were occluded and didn't split up.
