Joint tracking with event grouping and temporal constraints

Vision systems become more and more popular to be applied in monitoring tasks such as controlling traffic flows or for security issues. The analysis of target behavior is always based on its observed trajectory, which can be acquired by tracking approaches. Although the fashion of tracking-by-detection is favored by the research community, it still faces challenges like unexpected occlusion caused by background objects or other tracked targets, which can interfere the matching operation and result in tracking errors. In this paper, we propose a novel approach by aggregating prediction events within target groups and integrating a graph-modeling based stitching procedure to handle the above mentioned problems. The evaluation results on the UA-DETRAC benchmark demonstrated the state-of-the-art performance of our tracking approach.
