I genuinely don't really understand what's trying to be proven here. I mean, it's just how our eye+brain work indeed. You can make it "better" by dezooming on the images, or "worst" by zooming in, which is just as expected. It doesn't really seem far from other techniques for image compression, just a less good version of those ?
