Arbitrary-Scale Super-Resolution with Neural Heat ...
hrm. on nature portrait photography 600x600 upscale, it has a LOT of artifacts. Perhaps too far out of distribution?
That said, your examples are promising, and thank you for posting a HF space to try it out!

Hi, author here :) It shouldn’t be OOD, unless its too noisy maybe? And what scaling factor did you use? Single image SR is a highly ill-posed problem, so at higher upscaling factors it just becomes really difficult…

Perhaps parent comment used a .jpg as input? The model seems to artifact a lot on existing compression artifacts.
