Why are hands difficult for ai images?
In: 250
At the end of the day, computers are still just fancy calculators. AI is just mathematics, specifically statistics. You feed an AI a tonne of images, some are a single hand with 5 fingers, some are two hands together with 10 fingers, maybe some fingers are bent or hidden behind something, maybe there are multiple people’s hands in the image. The images are flat, technically the AI doesn’t even understand 3D geometry and camera angles, or how joints and rotation works, so you’ve confused the shit out of it. Computer says, well on average an image of a person has 7 of these pointy fleshy things going in this direction so I’ll draw that, even though physiologically it makes no sense.
And when it screws up, it’s really obvious, because we humans do understand 3D geometry, and the basic biology of having exactly 5 fingers per hand, and the different ways they can bend. Hands are one of those things that you can’t really think about statistically, which is the only way the AI knows how. Unlike say, eyes, which are more or less always the same shape and in the same position on a face, or a nose which can be big or small or anywhere in between without going into the uncanny valley.
You got the right answer already but your question reminds me of when people say “computers will never be like humans. Can a computer write a sonnet like Shakespeare?” and my answer would be “well, can you???”
Have you tried drawing a hand?
Our brain is very very picky when it assess important things that we know well.

Hands costed extra to paint in commissioned portraits because they were difficult. It’s reasonable to assume that 1) it’s also difficult for the pattern recognition software to get right 2) the examples it learns from are poor due to having few master works to learn from 3) there are fewer to reference from in total than other body parts
Speaking from an art perspective, humans are just very critical of hands. We have a very comprehensive idea of our hands (“to know something like the back of your hand”) and it’s a very complex weird shape compared to many other major features. Artists have a hard time emulating them as a result because they need to be perfect to be acceptable.
