To your eyes, maybe. To a machine, you have an array of pixels, each with different values which, using an algorithm, could be adjusted into something your eyes can resolve into a unique face.

Seriously? Look at https://www.androidpolice.com/wp-content/uploads/2020/06/04/... — do you really think there's enough information in those two rectangles to reconstruct the faces even approximately?

Hard to tell, I'm not a computer; but it does look better than most. To be fair (to me), I was basing my critique on the picture in TFA, which seems to have far more detail in it.

That said, the whole point of my post was that humans are really bad at judging this. Many blur algorithms can be reversed because they just modify the color values of the pixels in a reversible way. You can't always tell by looking at a picture what data is still there, in much the same way you can't see the stars in an ISO 200 picture of the night sky. It's not until you open it in GIMP and crank the exposure up to max that you see just how much data is there that your eyes couldn't perceive.

I kinda hope there's not only enough information there to algorithmically reverse, but that when you do that - all the de-blurred faces end up being George Floyd.
