Dense Scene Multiple Object Tracking with Box-Plane Matching
This addresses occlusion challenges in MOT for dense scenes, representing an incremental improvement over existing tracking-by-detection frameworks.
The paper tackles the occlusion problem in Multiple Object Tracking (MOT) for dense scenes by proposing a Box-Plane Matching method, achieving first place on the Track-1 leaderboard in the ACM MM Grand Challenge HiEve 2020.
Multiple Object Tracking (MOT) is an important task in computer vision. MOT is still challenging due to the occlusion problem, especially in dense scenes. Following the tracking-by-detection framework, we propose the Box-Plane Matching (BPM) method to improve the MOT performacne in dense scenes. First, we design the Layer-wise Aggregation Discriminative Model (LADM) to filter the noisy detections. Then, to associate remaining detections correctly, we introduce the Global Attention Feature Model (GAFM) to extract appearance feature and use it to calculate the appearance similarity between history tracklets and current detections. Finally, we propose the Box-Plane Matching strategy to achieve data association according to the motion similarity and appearance similarity between tracklets and detections. With the effectiveness of the three modules, our team achieves the 1st place on the Track-1 leaderboard in the ACM MM Grand Challenge HiEve 2020.
