Hello,

I've tried to run inference using the pre-trained model you provide on greyscale images and was expecting something along the lines the result attached on README, but what I get is just an enhancement (a good one) of quality of the image. How did you get the model to transform that greyscale portrait into a coloured one?

Thanks for your help and really great work!

Just to check - are you using the GFPGANv1.pth model or the GFPGANCleanv1-NoCE-C2.pth? The readme instructions use the latter, which has no colorisation (but also doesn't require CUDA.)

Hi @berry120 ,

I see, thanks a lot for the information. I'll try with the other model then :).

how about the whole image restoration. latter one only colorize the face part of the image, rest is still grayscale.
how can I colorize the whole image?
