I sometimes feel I can tell a lot about a person just from their appearance. Especially a face seems to hold a lot of information abot a person. When you add how he or she speaks, dresses, gestures, and how their facial expressions look, a lot of information is being revealed I think.

I don't claim to be better than average at getting to know a person from their appearance and it makes me wonder how much information is really there. Would an AI app, and in the future, a robot be able to tell a LOT about a person just from a photo of their face?
