About top-K highest quality score?

[aidevmin]

Thank you for your amazing paper. I have read your paper. You said that PGD keep top-K regions with highest quality score. As my understanding, for each ground-truth box, we will keep K feature pixels over all neck feature maps? Is that right?

@ChenhongyiYang Could you clarify this problem for me? I am confused about it. Thanks.

Hi. Yes, for each GT, the TopK is computed from all feature points across all feature levels, although in most cases those topk points will generated by the same feature level.
