How do you solve the noise/artefact problem ?

[JunbinWang]

Hi,

I am very interested about how you train the model to solve the image artifact problem caused by image compression (jpeg images) ?

I try some other SR models before, most of them can only handle png images and performs very bad in jpeg format image.

Best Regard, Even.

simply train jpeg denoising.

denoise: input image -> add jpeg noise -> CNN -> output image loss = MSE(input image, output image) SR+denoise: input image -> downsampling -> add jpeg noise -> CNN(upsampling) -> output image loss = MSE(input image, output image)
