Is there a library that can take an image...and do processing to determine things about it?

Question

Such as...is the image a person of female or male?

Is there such free tool out there, available?

Answer 1

if(person.hair.length > 10 && person.name != "richard stallman") { return female }

else { return male }

should work on most platforms

Answer 2

There are some. But most of them are extremely expensive (several 100k € - don't know if that is acceptable for you). One open source is here, but you can be happy if it can actually detect a face. It won't detect the sex of a person on the picture.

Answer 3

No, but version 3 when available will be able to tell you what the name of the main object in the picture is: seems easy but very complex.
