Facial Recognition Using Theory of Biometrics

While people have had the inborn ability to identify and compare different faces for millions of years, computers are just now captivating this. In this paper, the techniques of how computers are shaping your face into computer code are compared to millions of other faces are illustrated. How facial recognition software is being used in criminal investigations, elections and to protect your personal computer.

A facial recognition system is a computer application for automatically recognizing or verifying a human from a digital image or a video frame from videos. This can be done by distinguishing selected facial features from the image and a facial database. It is widely used in security systems and can be compared to other biometrics such as fingerprint or eye iris recognition systems.

3-D facial recognition system and biometric facial recognition system is focussed. This paper also illustrates future scope of enhancement of facial recognition system in India.
