This creates 'nice looking believable' images, but why do they also not show a comparison of the AI generated result with the hi-res original?

- nulbyte 5y agoI wondered the same. To me, there seems something slightly off about the supposedly upscaled images. I really want to see a legitimate comparison.

- hn_throwaway_99 5y agoThank you very much for posting the original. I agree with some of the other comments, while the generated faces look highly photo-realistic, in some cases they also look quite different from the actual person. Not that different mind you, but humans are obviously super sensitive to tiny changes on faces - it doesn't take that much to make it look like a different person altogether. For the non-face images it was much harder for me to really detect many differences, and they certainly didn't bother me.
- stedaniels 5y agoThank you for this link. The differences between the original and the upscaled SR3 model are highlighted mostly for me on the picture of the leopard. The facial markings are clearly different.
