Suggestions for better numerical stability about monkey-net HOT 4 CLOSED

Hi, thank you for your suggestion. I also think about this. I believe that adding epsilon to the denomitar may not be appropriate since this epsilon can be order of magnitude higher than the value itself. Instead I tried to add epsilon to a heatmap:

Which should potentially aliviete the issue of zero singular value, if this is not the case you can try to increase the epsilon.

In any case I found this variances problematic to work with and in follow up work, I eliminate them completely.

Hi,

Thanks for your response!

Do you mean you only model the mean of the keypoints in this case?

Not only the mean. I also estimate affine
transformation matrix near each keypoint.

I see, thanks for your suggestions :)
