normalize trimap #13

Hi, thanks for sharing your work. Just wondering -- why do you normalize the alpha image but not the trimap when training?

I'm not sure about what do you mean by normalizing alpha image and trimap. If you mean this line: https://github.com/Yaoyi-Li/GCA-Matting/blob/5a999be4b00bb482658fa7013a74a2b8acddc78e/dataloader/data_generator.py#L487 Our network takes a 3-channel one-hot trimap as the input, so the trimap need not to be normalized.
