WIP / Re: [FF7PC]FF7 SYW V3, Battle, world map and fields with ERSGAN (WIP)
« on: 2019-02-07 17:22:35 »Yeah, NNEDI3 (I meant that version) would be meant here for image doubling. At its time, it was the best scaler by far, and it yielded some very light denoising and great antialiasing as a side bonus. And it was developed with neural networks.
As for M(V)Degrain3, it's just the latest motion compensated denoiser I know of. It is quite slow (much more than, say, dfttest) and at its time struck a great balance between denoising and actual detail removal. Where can I read about KNLMeansCL and V-BM3D?

This is a really good (but sloooooow) artifact remover too: https://forum.doom9.org/showthread.php?t=173470
Doom9 has some good threads on all of em, and the vapoursynth fatpack supports all those filters right out of the box. You can also enhance those filters by using cutting edge masks to further preserve detail, like retinex.
Someones working on a GPU BM3D, but it doesn't support temporal denoising yet, which means it really doesn't have an advantage over the ML-based image denoisers that are out there.

Also, if you think MVDegrain3 is slow, just wait until you try BM3D or Oyster on the CPU
