Question about 2D conf for query generation #26

Thanks for sharing the great work!

Could you also share the idea or the reason why you choose 2D confs to generate the query embedding?

Looking forward to your reply.

We want to supply the MOTR tracker with the proposal confidence information. Actually, even a shared embedding across all anchors could also work suggested by Anchor DETR and DEB-DETR.
