Discriminator Architecture #60

Open Neerajj9 opened 4 years ago

Neerajj9 commented 4 years ago

Hello, First of all great work ! I had a doubt. The code for the discriminator has a MultiscaleDiscriminator while the paper does not mention anything regarding the same. Why is it so ? Were multiple discriminators used in training ? Or was a single discriminator sufficient ? Also what is the reason behind a Multi scale discriminator ?

The MultiscaleDiscriminator code was taken from original CycleGAN paper. But for this paper only 1 scale was used, i.e. the original 70x70 patchGAN. For matting, higher level context is not so important but individual patches make more sense.
