I am at a hackathon, and I spent 8 hours on trying to implement Patch match for N channels of images.
I know this is very unreasonable, but I am sincerely frustrated, and hope somebody from this community can help me implement.
I want to implement this paper: http://gfx.cs.princeton.edu/pubs/Barnes_2009_PAR/patchmatch.pdf 17
but instead of 3 channels, I want it across N channels. This is a for a neural network, and I will be more than happy to collaborate with whoever helps me.
I would like to add this as a pytorch extension https://github.com/msracver/Deep-Image-Analogy/blob/master/windows/deep_image_analogy/source/GeneralizedPatchMatch.cuh 17
Help is greatly appreciated.
