details about image denoising #19

Hi! Thanks for the great work! This paper mentioned that mganprior can also be used for image denoising. But I'm not sure how to achieve it. Could you give me more details about image denoising? Like this image Thanks again for your great work!

In practice, we assume that the noise mode / noise pattern is already known. In that case, we can only use the noise-free region to reconstruct the image. With the pre-trained GANs as prior, the noise-include region will be recovered automatically.

Is that means wo have the noise image and the "noise mask" to be the input, like the inpainting mask?

ShenYujun commented 3 years ago

Yes, it requires to pre-know the noise model.

Got it! Thanks for your reply!
