Quantitative metrics of evaluation #19

Open smoreira00 opened 1 year ago

smoreira00 commented 1 year ago

When measuring PSNR, SSIM, and LIPIPS, does it take into account the pixels we previously masked? Or does it discard those pixels? For example, in my images I have a black border that I'm masking, but I'm not sure if in the evaluation those pixels are considered or if it only considers the pixels that are not masked.

Thanks for your question. Actually, there was a similar discussion in a previous issue. I've included my relevant reply below.

In my implementation, I also evaluated those black pixels in order to keep a coherent manner to computing other metrics, like SSIM. Since SSIM is calculated on image windows, it is inconvenient to left out those masked areas. Thus, I simply take the masked images for evaluation in all metrics.

For more discussion, please refer to #11.

Thank you so much! Left another doubt in #11.
