Questions about the paper

[mosquitobite]

Hi~Interesting work! I have a question about Figure 6 while reading your paper. I write it down here so that anyone confused by the same problem can find this.

What does CDF of PSNR/SSIM mean? How is it calculated? How to use this analysis for evaluating different methods?

These questions may seem to be naive, but I have never met CDF of PSNR/SSIM before. Hope you can give some instructions. Thanks!
