    These guys developed a new algorithm to upscale pixel graphics. On most source material it's much better than existing upscalers.

    Here is the document with lots of images: http://imgur.com/a/gRXPJ

    There is a sample video with a snippet of Super Mario gameplay processed with their upscaler/vectorizer:

    The original source is kinda down...maybe a case of too much traffic.

    Edit: Better source with PDF, more pics, videos.

    Wow, that was an awesome read. Thanks! The effect definitely varies, but in a lot of instances, their method certainly looks better in the upscaling. A lot of the time though, it looks kind of like a sloppy paint/blur job. (As in, actual paint, no MS paint.) Still though, it's very interesting. It'd be interesting to see a full game use this algorithm. Maybe as a filter?

    Here's hoping this goes into the next build of snes9x or ZSNES.

    I'd love to see this as an application for desktop PCs.
    habbo hotel would look awesome

    It depends a bit on the type of source.. not all pixel graphics are suited.

    The new look it creates has it's own charm and alters the feeling of the original pixel art a lot. It's different, but not necessarily inferior.

    Another thing is, an algorithm can never know how a 1-2 pixel detail has to look like exactly, if it was intended to look sharp or rounded, so it will never be accurate on everything.

    But I guess it will work quite nice on a lot of NES & SNES games. I hope it will be implemented in an emulator soon.

    Oh, how would this look with 3d-games like Golden Sun DS? That'd be awesome!

    I hope this makes it into some retro emulators. It's a bit crude in some areas, but it would be fun to mess around with.

    I don't get it, what's wrong with pixels?

    This would be a cool option in emulators as long as it can be turned off. (retro purist)

    I got nothing to say about that but the depixeled Yoshi sprite in the link looks really really disturbing. Pixeled Yoshi is better.

    Also, I'd love to see a depixelized Doom [​IMG]

    A lot of people seem to have a polygon fetish these days.

    You lot should all be ashamed of yourselves. Pixel art is a dying talent and here you all are trying to give it that final kick off the roof. If you need to play old games on a huge TV, then do a pixel perfect resize, those pixels were designed to be seen, blurring and smoothing and stretching is not how these gfx should be viewed. There is no reason at all to ruin nice pixel art like that, if you don't like how it looks then don't play those games, simple.

    Nothing is wrong with pixels. I love pixel art.

    But this is impressive.

    Let's all take a page from the book of Porygon, or rather 3.

    Sharp edges aren't always a bad thing.

    What I'm particularly impressed with is how the algorithm successfully interpreted how the mouth should be displayed. I want to double-check this against other upscalers like SuperEagle now.

    I don't understand how that makes Porygon any less epic or the other 2 any less fail.

    This.
    Plus add some nice looking-non intrusive fake scanlines ( yes, the pixel artist took TVs scanlines into account when drawing their sprites and backgrounds ) and there you go with a true representation of the art !
