Why are hands difficult for ai images?
In: 250
There was a youtube video that explained it so well… can’t remember if it was steve Mold or Sabine or someone else. Anyways, AIs that have difficulty with hands are those that are only trained on 2D pictures and lack a model of how things are in the real world in 3D.
Those AIs recognize a human face whether it is a front picture (2 eyes, 2 ears) or profile (1 eye, 1 ear), BUT they don’t know that the difference between the two pictures is a rotation on the 3D space.
If you follow subs like r/confusingperspective you’ll soon realize that there is plenty of pictures where people seem to have 3 legs or 3 hands. But there is less confusing perspective pictures about heads, maybe because when we take picture we make sure that head and body are prominent in the shots we take.
So, a lot of confusing perspective around hands and feet… confusing to us, humans who have knowledge of the 3D world. Now imagine you are a software that only analyzes pixels in 2D.
