Analytical Study of Face Recognition Techniques

In today’s world face recognition, applications attain great popularity due to best application of image analysis and availability of feasible technologies. It has a wide scope of applications in different fields like pattern recognition and commercial market. A large number of researches have been done research within this field. The different area's Researchers, including computer science and neuroscientist are working within this field. Due to distinct variation in facial expression, occlusion and illumination, face recognition process becomes more challenging from last few decades. In this paper, we critically evaluate different state-of-the-art face recognition techniques. Strengths and weakness of different techniques are identified, which helps in the future research.
