Face recognition is a biometric technology to identify or verify one or more persons from still or video images of a scene using stored database of face images. It has many advantages over other biometrics like finger-print and iris recognition.This paper gives an overview of the current research work in face recognition and gives the direction to develop a robust face recognition method that can be useful for many commercial applications. This paper reviews the approaches in 2D and 3D face recognitions, databases available for face recognition and recognition accuracies in detail. Examples given in this paper are taken from the published work of the researchers in face recognition with references.
