MOTRv2: Bootstrapping End-to-End Multi-Object Tracking by Pretrained Object Detectors. (arXiv:2211.09791v1 [cs.CV])

In this paper, we propose MOTRv2, a simple yet effective pipeline to
bootstrap end-to-end multi-object tracking with a pretrained object detector.
Existing end-to-end methods, e.g. MOTR and TrackFormer, are inferior to their
tracking-by-detection counterparts mainly due to their poor detection
performance. We aim to improve MOTR by elegantly incorporating an extra object
detector. We first adopt the anchor formulation of queries and then use an
extra object detector to generate proposals as anchors, providing detection
prior to MOTR. The simple …
