Bad human hand creation in AI

[Peter_Frommenwiler0327]

I tried to create a family scene in the Kitchen but always the hands are worse. There is obviously a wrong algorythm. More or less five fingers or no fingers. It is horrible no solution at all. is there any help?

It's not just Adobe's Generative AI. Here's one paragraph from Britannica that explains the issue pretty well.

https://www.britannica.com/topic/Why-does-AI-art-screw-up-hands-and-fingers-2230501

"Another issue is that AI doesn’t actually know what a hand is. In two-dimensional images, hands can appear in dozens of different positions: waving, flexing, holding an object, clenching a fist, or poking out of a pants pocket, partially hidden from view. Humans know that these visual discrepancies illustrate how a hand works. AI, without access to the three-dimensional world, knows only how a hand appears. Identifying a fist, thumbs-up, or peace sign as a hand is an impressive feat for AI, and we can hardly blame it for assuming a real hand could be a combination of the three."

You can use traditional methods in Photoshop to clean up Generative Fill.

If you google this, you'll see that this is nothing special for Firefly/Photoshop; they all do this. It's an excellent illustration of the deficiencies of AI in general. It has no "understanding" of what it's doing. It's just a machine.

EDIT Jane beat me with a more comprehensive explanation - but you get the idea.

MidJourney renders hands better. It's still rolling the dice but the odds are in your favor.

I am not sure Firefly will ever be able to fully »catch up« to the other generative AI image creating software because Adobe uses a fairly restrictive approach to training material because of legal considerations.

Yes, but this is all related to how AI basically works.

I heard something interesting on the radio the other day: Asking ChatGPT to tell jokes. It was hilarious - not because the jokes were funny, but because they were spectacularly not funny. In the discussion some explanations were offered, the most credible being that AI is built on prediction and probability - but a joke is breaking predictability, a 180 degree shift in context. AI can't do that.

AI can never surprise! It can only repeat. It can not learn from one situation and apply that to another situation, because that's breaking predictability, and AI can't do that. Hence the deformed hands.

It has also struck me how ridiculously easy it is to recognize AI-generated posts here in the forum. They jump out. Same with AI-generated images. They are boring and astonishingly unsurprising. It takes cliche to a new level.

If anyone still thinks AI is "creative", they don't understand the meaning of the word.

It also surprises me how many unedited AI images we see, complete with the usual defects such as strange hands, as raised in this thread, and sometimes worse such as extra, or misplaced, limbs. Few people would post an unedited photograph and yet it often seems to happen with AI generated images. Strange.

Yeah. It seems AI kills not only creativity, but also basic quality control.

Entropy seems to be the word that sums it all up. Luckly, the resistance movement is active and hasn't given up yet 😉

@Peter_Frommenwiler0327  that's nothing. My father-in-law passsed away last year, and I was doing his photo for the picture at the head of the casket. His head in the orginal photo was tilted, and I wanted to see if AI can quickly fixed it...as soon as I put a prompt in, and hit enter, my wife comes in, and soon after, my father-in-law head is now changed to a blond guy (fyi, my FIL is Chinese), so I quicky hit regenerate, and then it gave me woman's head, by then, I already knew...I was in the doghouse... I eventually did it by hand...
