Show quality of upscaling in comparison

Open LuminescentMoon opened this issue 4 years ago • 3 comments

Show difference quality as a numerical value between original (full size) image and upscaled image in the waif2x implementation comparison chart.

Probably using SSIM. Would be a informative comparison.

@f11894 This is a good start. Interesting note, caffe is a miniscule amount better at magnifying than ncnn. You mind plotting SSIM for denoise only with all models?
