This would be awesome if it was available as a scaler for high-DPI screens and old apps. Or even bundled into televisions for upscaling.

The paper does note that it is designed for hand-edited pixel art, where every different coloured pixel is treated as significant. So I wonder how it behaves when scaling photos?

(Edit: the paper does note that it doesn't do well on anti-aliased graphics...)

Televisions have upscale algorithms. But nothing like this. But they don't need anything like this because they don't scale pixle art with sharp borders and very low resolution. They scale video footage (which one could say is "anti-aliased") with about 640x480 resolution.
