In the days after the US Department of Justice (DOJ) published 3.5 million pages of documents related to the late sex offender Jeffrey Epstein, multiple users on X have asked Grok to “unblur” or remove the black boxes covering the faces of children and women in images that were meant to protect their privacy.

Put all these creepy bastards on a publicly viewable list.

[–] cley_faye@lemmy.world 7 points 2 days ago (1 children)

Didn't they already do that in their public posts or whatever? They don't care.

Won't work and if it does work, the resulting image has little to nothing to do with the original.

Source: I opened a badly taken .raw file a few thousand times and I know what focal length means, come at me.

[–] HereIAm@lemmy.world 2 points 2 days ago (1 children)

Do you have a good way to remember which way fast and slow f. stops go? I always have to trail and error when adjusting camera settings to go the right direction or especially listening to someone talk about aperture.

[–] Krauerking@lemy.lol 4 points 2 days ago (1 children)

Wider open you let in more light, and want faster shutter speed, more closed you get less light and want a longer shutter speed.

And f stops work backwards. Think of it as percent of sensor covered. The bigger the number the more covered it is and the smaller the hole/aperture.

[–] HereIAm@lemmy.world 3 points 2 days ago (2 children)

So Wide open = low coverage = small f stop -> lots of light -> "fast" shutter speed. And then the other way around. I think you finally worded it in a way it can stick in my brain! I like thinking about the f value as how much you're covering the lens.

[–] Zink@programming.dev 3 points 2 days ago

To add more specifics here for you, note that the f-stop is usually shown as a fraction, like f/2.8, f/4.0, etc.

So first of all, since the number is on the bottom of the fraction, there's where you get smaller numbers = more light.

It's also shown as a fraction because it's a ratio, between your lens's focal length (not focal distance to the subject) and the diameter of the aperture.

So if I'm taking a telephoto shot with my 70-200 @ 200 with the aperture wide open at f/2.8, that means the aperture should appear as 200/2.8 = 71.4mm. And that seems right to me! If you're the subject looking into the lens the opening looks huge.

I like trying to simplify stuff to basic language and I am happy it was helpful

unblur the face with 1000% accuracy

Or percentages

[–] ToTheGraveMyLove@sh.itjust.works 100 points 3 days ago* (last edited 3 days ago) (14 children)

Are these people fucking stupid? AI can't remove something hardcoded to the image. The only way for it to "remove" it is by placing a different image over it, but since it has no idea what's underneath, it would literally just be making up a new image that has nothing to do with the content of the original. Jfc, people are morons. I'm disappointed the article doesn't explicitly state that either.

[–] usualsuspect191@lemmy.ca 49 points 3 days ago* (last edited 3 days ago) (4 children)

The black boxes would be impossible, but there are some types of blur that keep enough of the original data they can be undone. There was a pedofile that used a swirl to cover his face in pictures and investigators were able to unswirl the images and identify him.

With how the rest of it has gone it wouldn't surprise me if someone was incompetent enough to use a reversible one, although I have doubts Grok would do it properly.

Edit: this technique only works for video, but maybe if there are several pictures of the same person all blurred it could be used there too?

Several years ago, authorities were searching the world for a guy who had been going around the world, molesting children, photographing them, and distributing them on the Internet. He was often in the photos, but he had chosen to use some sort of swirl blur on his face to hide it. The authorities just "unswirled" it, and there was his face, in all those photos of abused children.

They caught him soon after.

A 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.

[–] altkey@lemmy.dbzer0.com 12 points 3 days ago (1 children)

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.

Yeah, but this type of machine learning and diffusion models used in image genAI are almost completely disjoint

They think that the AI is smart enough to deduce from the pixels around it what the original face must have looked like, even though there's actually no reason why there should be a strict causal relationship between those things.

I am so glad I no longer interact with that dumpster fire of a social network. It's like the Elon takeover and the monetization program brought out every weirdo in the world out of the woodwork

late sex offender Jeffrey Epstein

I'm so done with all the whitewashing. "Sex offender" sounds like I behaved wrong in consensual sex. What this prick was is a pedophile. A child rapist. A kid-abuser and -rapist. But surely no "late financier" or whatever else media chose over the facts.

[–] pinball_wizard@lemmy.zip 17 points 2 days ago (2 children)

Also a slaver and child abductor.

[–] SaraTonin@lemmy.world 6 points 2 days ago

And, it seems, murderer

[–] Dyskolos@lemmy.zip 4 points 2 days ago

Oh right, my bad 😐

How do these AI models generate nude imagery of children without having been trained with data containing illegal images of nude children?

[–] AnarchistArtificer@slrpnk.net 58 points 3 days ago

The datasets they are trained on do in fact include CSAM. These datasets are so huge that it easily slips through the cracks. It's usually removed whenever it's found, but I don't know how this actually affects the AI models that have already been trained on that data — to my knowledge, it's not possible to selectively "untrain" models, and they would need to be retrained from scratch. Plus I occasionally see it crop up in the news about how new CSAM keeps being found in the training data.

It's one of the many, many problems with generative AI

[–] RedGreenBlue@lemmy.zip 15 points 3 days ago

Can't ask them to sort that out. Are you anti-ai? That's a crime! /s

Sounds about right for x users

[–] nymnympseudonym@piefed.social 20 points 3 days ago (1 children)

I doubt any of these people are accessing X over Tor. Their accounts and IPs are known.

In a sane world, they'd be prosecuted.
In MAGAMERICA, they are protected by the Spirit of Epstein

[–] clay_pidgin@sh.itjust.works 10 points 3 days ago

What crime do you imagine they would be committing?

I don't know what they hope to gain by seeing the kid's face, unless they think they can match it up with an Epstein family member or something (seems unlikely to be their goal).

[–] melsaskca@lemmy.ca 13 points 3 days ago (1 children)

Of course they are. Who's left on Twitter nowadays? Elon acolytes?
