Different approaches for human face detection leading to real time face analysis: A survey

Abstract: Now a day�s recognition of faces is very popular to identify or recognize a person. Face recognition plays a major role for security, surveillance and in forensics. Before recognizing the faces, first we need to detect the face and extract the vital features from the face image and then classification is performed on the face image for recognition process. Face detection is the initial step forface recognition. In this paper we discussed about some of the methods used for face detection and also face recognition. In addition to this, the advantages and disadvantages of the surveyed methods are also stated which will help for further development and improvement of the system leading to improved face analysis works.
