Face detection is a computer technology that determines the locations and sizes of human faces in arbitrary (digital) images. It detects facial features and ignores anything else, such as buildings, trees and bodies.
Now we have ability to implement this feature on client-side by using jQuery plugin which detects faces in pictures and returns theirs coords. This plugin uses an algorithm by Liu Liu.
