Comment on Epstein Files: X Users Are Asking Grok to 'Unblur' Photos of Children
Barracuda@lemmy.zip 16 hours agoA swirl is a distortion that is non-destructive. Am anonymity blur averages out pixels over a wide area in a repetitive manner, which destroys information. Would it be possible to reverse? Maybe a little bit. Maybe one pixel out of every %, but there wouldn’t be any way to prove the accuracy of that pixel and there would be massive gaps in information.

Swirl is destfuctive like almost everything in raster graphics with recompressing, but unswirling it back makes a good approximation in somehow reduced quality. If the program or a code of effect is known, e.g. they did it in Photoshop, you just drag a slider to the opposite side. Coming to think of it, it could be a nice puzzle in an adventure game or one another kind of captcha.

You’re right. I meant more by “non-destructive” that it is, depending on factors like intensity and known algorithm, reversible.
