Please see the explanations about inverse warping here:

this should help you understand!

Also your paper said that "A keypoint is considered to be matched correctly if its predicted location is within a distance of α · max(h, w) of the target keypoint position". So i don't know why you code compare with source points instead of target points.

Thank for you reply :)
So, it means that, i just replace "source points" and "target point" in the code and got the natural result ?.
But it too weird for me...
Because in the code: You warped source images -> target images, and using theta result to get inverse warping...
So, could you tell me, how to get target point from source points and theta result ?
Thank you !

so do you understand his means? I'm also confused this opinions.

@lixiaolusunshine yes, i understood him. Clearly that, the paper said that source points to target points, but in the source code is totally inverse.
from cnngeometric_pytorch.
so in his paper he got the estimated inverse affine parameters from the featuregression layer, then use this inverse mapping to warp the source image into the target image?
from cnngeometric_pytorch.
@lixiaolusunshine sorry, i cannot catch up your mean. In his paper, very clear that, use GMM, find a list of parameters, from parameters => warp => loss.
The only difference is when he compare the result. He compare the target points, but in code, we never get target points for the parameters, instead of is source points.

@binhmuc
Thanks for your issue.
Link about inverse points method is broken.
If you know how to do the inverse points, I would like to know.
The owner of this source code does not appear to be replying at this time.
