GBU based face recognition techniques: A review

A large number of face recognition algorithms have been developed in last decades. Over the past four decades, performance of Face Recognition on frontal faces in controlled environment has improved significantly but frontal faces with uncontrolled environment and expression remains a challenge. The GBU Based Face Recognition Techniques focuses on the attention of the fundamental problem of comparing single frontal face images across changes in appearance. This paper introduces many of the recent success and future challenges that are faced by the researchers in GBU Based Face recognition as well as techniques used so far.
