[ARTICLE] Depixelizing Pixel Art

Hi there,

I just found a great pixel-art scaling algorithm by Kopf and Lischinski, which can produce gorgeous results:

And please do not miss the paper (link is included).

I really like what I see. If anyone stumples upon a full implementation of that procedure I would be happy to hear about that.

well as a pixel art fan i don't see anything gorgeous about those horrid vector results..

if redone in vector such stuff should be handled by an proper artist and not an soulless algorithm who does not even understand what those few pixels wanted to represent..

and i think they shown something similar last year.. i recall some of the conversions..

anyway .. "rundgelutscht" is not better imho..

I personally hate those types of filters, you are better off spending more time adjusting them by hand then something which looks like it was drawn in adobe design or whatever uses vector lines.

Not to say it's wrong, just doesn't keep that sprite feel at all and turns said item into something of low flash quality in feeling.

Well, for those not wanting a pixel art look, this could be quite useful.

For instance someone could take old low res graphics and upgrade them to HD, in order to support retina or universal apps.

I personally would like to see this algorithm in action under real conditions. For example when scaling my graphics up to iPad-3-retina-resolution next year.

The shown examples are rather big-blow-up, if you know what I mean. Doubling resolution would be interesting.

This looks like a public research paper, so perhaps someone will code a tool from the algo so we can test it out? :P

I used to be real gung-ho about pixel art before. Didn't help that HQ filter results were often questionable. But recently, especially with the popular reception of Jetpack Joyride, I'm starting to understand the other side of the equation. Pixel art is seen as old-fashioned by many younger customers, and a fresh coat of HQ3x can help alleviate that problem without the need to invest limited resources.

Regardless of if it's desirable or not, that's pretty impressive tech, I really like what it does to the Space Invaders for example.
