Bidirectional Matching

[lzl2040]

In forward matching, what is the dimesion of the points on the reference mask Pr? And what does the L means?

[Z-MU-Z]

In forward matching, the dimension of the points in Pr is 2D. That is, each point has x and y coordinates representing its position in the image space and corresponds to a patch-level feature. L represents the total number of points falling on the reference mask.

For forward matching, did you select point features from patch featrues of the reference image to calculate sim(Pr, Zt)?

@YHDang We use all points on the reference mask in the forward matching.
