For inpainting model, Mask

[ErwinKC]

For inpainting model, there's a 4 channels input, mask will be one of them and the output is 3 channels data. I'm wondering does this mask contribute to the network, or I can delete it and make input for 4 channels as well. Best regards, Thanks.

The four channel input contains masked image and mask. I just follow the LaMa and do not validate the contribution of mask.
