A Detailed Study on Face Recognition Techniques

Face recognition has received considerable attention recently, as a promising approach for security and surveillance. Face recognition have the challenges of the light illumination and variations in the poses in various fields. The main aim of this work is to find out the optimum approach which can be used against these challenges and to study various approaches. The problems comes in the various algorithms are also defined and how these problems are resolved by using the new approaches. In this paper the different types of face recognition approaches and the various performance matrices for face recognition on the basis of different parameters have been discussed.
