Rethinking the competition between detection and ReID in Multi-Object Tracking

Liang, Chao, Zhang, Zhipeng, Zhou, Xue et al.

Understand

Due to balanced accuracy and speed, one-shot models which jointly learn detection and identification embeddings, have drawn great attention in multi-object tracking (MOT).

  • However, the inherent differences and relations between detection and re-identification (ReID) are unconsciously overlooked because of treating them as two isolated tasks in the one-shot tracking paradigm.
  • This leads to inferior performance compared with existing two-stage methods.
  • In this paper, we first dissect the reasoning process for these two tasks, which reveals that the competition between them inevitably would destroy task-dependent representations learning.
