I think that object recognition is hard because humans have much more data than computers. People see with two eyes which can focus on different distances, so our brain has 3D data to learn from. We later learn to recognise the same objects on pictures.

Computers usually start from flat pictures, and that trips the learning process.

I have zero data to back it up. Just my hunch :D

So children that's blind on one eye take longer to learn to recognize objects?

No but they cannot see depth very well because they can't use stereoscopic vision (triangulate). However, there are other cues that are used to infer for depth such as covered edges(if one object partially covers another then it is closer to you), perspective (if two objects that you know are similar in size but one appears smaller then it is farther) etc.

A friend of mine who cannot see with one eye and yet he is a painter. One thing I know he cannot do is drive a car.

Not necessarily longer but it would probably have an effect on precision.
