Is w&h ratio in propasals a hyperparameter? #178

I found the wh is hard-coded and fixed by default in gen_encoder_output_proposals(). Have you tried the settings of different size ratios? I noticed there is an option for learned wh but no results were provided in the paper (since the original DeformableDETR). Maybe it is not sensitive?

We did not try it, but our method learns a box offset on the proposed boxes. I guess this has a similar effect as learned w and h.
