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:

GCA-Matting/dataloader/data_generator.py

Line 487 in 5a999be

alpha = cv2.imread(self.alpha[idx % self.fg_num], 0).astype(np.float32)/255

Our network takes a 3-channel one-hot trimap as the input, so the trimap need not to be normalized.
