Show quality of upscaling in comparison #38

Open LuminescentMoon opened 5 years ago

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?
