Details about producing keypoint correspondences

[duducheng]

Hi,

I'm interested in the keypoint correspondences (Sec. 5.3 Correspondences).

I haven't found the code for keypoint transferring using dense correspondences. I'm curious how it is done.

BTW, it looks like finding a coordinate in the template space / source shape space into a target shape space is non-trivial problem. Following a concurrent study of DIT (https://arxiv.org/abs/2011.13650), they establish the correspondences using the nearest neighbors in the template space. Do you use the same strategy?

Thanks!
