I'm a little bit skeptical of the process. How do you "improve" the image and still get the details back? When you downsample/blur, you lose information. Does he keep the original and splice parts of it back? If so, how does he decide which to splice where? And if it's just using pixel color statistics when you up sample, that would work on most of the single color textures in the video, but how would that work for the brick road with the drain? The seams between the bricks are directional, so there'd have to be some way to account for that. Anyone got a good guess? (or a paper for that matter?)
