Q1: YES. We apply HungarianMatcher to get the corresponding queries, and then use ground-truth boxes to extract RoI features.
Q2: NO. The target frames only take part in tracking head at training phase.
Q3: NO.

In the Dynamic Instance Embedding part, do the key frame share queries($q_{t-1}^{*}$ in formula(4) ) with the reference frame? Or another HungarianMatcher is needed to get the reference frame's exclusive queries?

from queryinst.

Yes, we inference querytrack on reference frame (with torch.no_grad()) and apply another HungarianMatcher to get the assignment between queries and ground-truths.

Thank you! And could you please tell me the weights of ClassificationCost, BBoxL1Cost and IoUCost when getting the assignment between queries and ground-truth bboxes of the reference frame? Thanks again.
