How far has image recognition software gone in development?
My friend, a photographer who mostly works in stock photo photography, has a bunch of images. Is there some software available which offers the options to "recognize" the number of people in the photos and to sort them according to that (he had some other wishes as well ... but I can't remember those now
I myself, do not know anything on the topic so it's hard to be specific on what I'm looking for. Or whether does something like that actually exists.
I'd appreciate any advice on the subject though.
