Why the fuck wasn't this posted here, you fucking redditor weebs?

It's a magical 2D art scaler/denoiser. Someone should give it one of those 320x420 dakimakura samples and post the results.

More comparisons I made: http://imgur.com/a/2AAYs
It does well over all. It was negligible with lewd Konata over bicubic, but over the photo of fig Konata it was by far the best. The weird one with Miu and Chiyo is also better than bicubic by a rther large margin in my opinion. It also is best on the photo of the gay nigger sucking on the candy cane. It is also the best on the doujin screencap, but the dots are now to big (still better than blurry dots though).

It does well.
