FairMOT: On the Fairness of Detection and Re-Identification in Multiple Object Tracking

Zhang, Yifu, Wang, Chunyu, Wang, Xinggang et al.

Understand

Multi-object tracking (MOT) is an important problem in computer vision which has a wide range of applications.

  • Formulating MOT as multi-task learning of object detection and re-ID in a single network is appealing since it allows joint optimization of the two tasks and enjoys high computation efficiency.
  • However, we find that the two tasks tend to compete with each other which need to be carefully addressed.
  • In particular, previous works usually treat re-ID as a secondary task whose accuracy is heavily affected by the primary detection task.
