Not really. The images aren't pixelated as an effect - it's just a representation of the actual number of pixels taken from the ground truth.
You can just as well take these pixels and apply any kind of blur filter - you still wouldn't retain any more information. If you go from say 1k x 1k pixels down to 100 x 100 pixels, you end up with 1% of the original information, no matter what you do.
- contravariant 6y agoI think they may have been thinking of just blurring rather than actually lowering the amount of pixels. A Gaussian blur doesn't really remove as much information as you might expect. Although it's very sensitive to noise.
- qayxc 6y agoBut that's something else entirely then - the very idea of upsampling is based around taking a lowres picture and turning it into a hires version.
- contravariant 6y agoBoth pixelation and blurring are used to anonymize faces, which this very article is about, so I can see the relation.
