Ranker is not used?

[ducha-aiki]

Hi,

I apologize for possible confusion, but it looks like the ranker is not used at all, when getting topk keypoints?
At least, that is what I see from the source code - the keypoints are sampled according to the point score, and the ranking score is only sampled for existing ones (within the number of selected keypoints)
https://github.com/cvg/RaCo/blob/main/raco/raco.py#L587C1-L616C54

To put is blunt, with current code user have to use, say 4000kpts and then sort and crop them by ranking manually, otherwise ranker is useless?

Best, Dmytro

Hi Dmytro, thank you for your interest in our work! We do not sample from the ranker's heatmap, but use it to reorder keypoints that the keypoint detector already selects as salient. Your example is accurate, you must first sample a larger number of keypoints from the detector and then select the top K based on the ranker score.
