Towards Occlusion Handling in Visual Tracking-by-Detection Systems

Yao Yeboah, Zhuliang Yu, and Wei Wu
Abstract—Occlusion is a common problem encountered in various tracking applications. This paper addresses occlusion within the context of real-time tracking. Contributions of the paper are two-fold. Firstly, the paper studies the occlusion problem within the context of tracking-by-detection. Secondly, a 3D approach that allows for tracking-by-detection algorithms to be extended towards effective occlusion handling is put forward. The proposed approach achieves an efficient incorporation of depth features into the circulant tracking framework, thereby achieving rapid object detection, tracking and robustification. Finally, a patch-based modeling strategy for depth features, coupled with a robust occlusion estimator is proposed. The resulting scheme allows for the tracker to achieve occlusion detection, tracker recovery and a significant alleviation of the drift problem associated with tracking-by-detection state-of-the-art. Experimental results on benchmark sequences demonstrate the effectiveness and robustness of the proposed scheme. The superiority of the scheme is further established in comparison experiments with state-of-the-art.

Index Terms—Circulant tracking, occlusion-handling, robust tracking, 3D tracking.
