HQ4X and Ours are the clear winners if you must resample like this; the downsides are that HQ4X occasionally has jaggies and Ours makes makes a lot of fine details look "blobby". The Vector Magic results reminded me a lot of this: http://www.cowboybooks.com.au/html/acidtrip1.html

This is a pretty old paper, but I hadn't seen the live demo. That's pretty cool. A problem with this algorithm is that it's pretty slow. It would be hard to use it for real time scaling. I think that it's pretty cool though for any precalculated conversion to vector format. It would also be pretty cool if there were software that allowed you to create a pixel art image with a live preview in this format and the abili…

A problem with this algorithm is that it's pretty slow. It would be hard to use it for real time scaling. Even if it's too slow for realtime on today's hardware, I'd love to see some prerendered sample videos.

Earlier quoted context omitted.

While something similar would probably be better, this is heavily optimized for pixel artwork. Lots of curves, shading, and most importantly - limited colors. UI is generally much straighter, less shaded, with far more colors. Here's an example of UI that's scaled with potrace (a similar algorithm): http://i.imgur.com/jDq4M7e.png (left side is the converted side, right side is nearest-neighbor. Top is 3x, bottom is 2…

1. That looks awful. 2. We just need vector-based icons already.
