Resampling

Vectorisation probably.

>Vectorisation
Is that specific software?
Ofcour I know what vectorisation is,just did not realize it is also name of some specific software.

The free vectorisation tools tend to be more work than hand-redrawing it.

>>60896023
Edge directed interpolation is a thing. I don't know about any FOSS tool beyond proof on concept but some of those methods should be fairly easy to implement.

>>60896023
write your own implementation in matlab, casual.

(ignore the homepage, I forgot to change that)

is https://research.googleblog.com/2016/11/enhance-raisr-sharp-images-with-machine.html a meme?

>>60896494
Is this using deep learning? I saw some examples before and it can have pretty great results, but I imagine that the performance would be rather impractical for everyday use.

>>60896528
ok after doing a bit of research, it's 100% a meme
pretty much a neural network trained to undo 1 downscaling algorithm by (((Google)))

>>60896636
Being a meme doesn't make it useless. I don't know about this particular thing, but I remember some anon linking to some neural network upscaling thing (I think it was even libre, but it used CUDA) which had pretty great results.

waifu2x is the same shit trained specifically on anime and manga images, and yes it's open source and has been around for ages
