About the reg_branch in MaptrV2Head

[gaosanyuan]

In MaptrV2Head, I found that reg_branch is used in two aspects. firstly, it is used to refine referece points in the transformer decoder; another term, it is used to predict points. How to understand that the reg_branch is capable of the two tasks. Thanks.

in maptr, inter_references and outputs_pts_coords and exactly the same. in maptrv2, inter_references and outputs_pts_coords_one2one are exactly the same.
