Vector Depixelization

by Anapan Mon Mar 03, 2014 2:12 am

I've been searching for real-time implementations of the Vector Magic and Kopf/Lischinski "Ours" pixel scaling algorithms shown here: ... /pixelart/

I found some videos of them prerendered!

Vector Magic
Kopf/Lischinski "Ours"

Too bad they didn't render them in 1080p, still, this just makes me want a realtime Vectormagic filter even more. All the pre-SNES/Genesis games would be hilarious!

It seems that currently they are too slow and no source-code is available so they're not implemented in any emulator and the newer Xbr filter (mentioned at the bottom) is rivaling the "ours" filter realtime already. There are a couple people working to implement the "Ours" one into GIMP as Libdepixelize and standalone as Depixel however.

I hope that a vector-based one that can be applied to each sprite/background layer separately with adjustment of the curves, corners, gradient implementation and solid-guessing/splines does get implemented as a loadable filter for emulators one day. Not that I don't prefer a good NTSC scanline filter, but being able to make changes to the filter would make for some interesting visuals.

Just think, it if guesses well enough the Asteroids ship could be a triangle again in a 2600 emulator. :lol:
