Can Best-Buddy Loss train without GAN and perceptual loss?

[Ken1256]

Will it better than L1 loss? Thanks

Thanks for the nice comments. We only incorporate our BBL into the adversarial training, outperforming than L1 loss. You can try your proposal.

get_flat_mask l_img = (0.2989 * r + 0.587 * g + 0.114 * b).unsqueeze(dim=1)

0.2989 0.587 0.114 where the RGB number come from?

It just converts a color image to a grey image...
