An inborn quality in humans that they can recognize and distinguish between faces. But the computers have also proved their ability of recognizing and distinguishing faces. Scientist named Woody Bledsoe along with Helen Chan Wolf and Charles Bisson configured the computer to recognize and identify the human face in the mid-1960s and since then the facial recognition tech has come a long way.

A facial recognition system is nothing but a computer application which identifies and verifies an image created on the spot of a face, by matching it with a given set of different digital images or video frames in a storage one by one. Such technique is mostly used in security systems which usually compare with other biometrics techs such as in fingerprint or eye iris recognition systems
