Research On Key-Technology Of Face Recognition Theory

ID authentication is a common problem in our daily life. People have to prove their ID so often. As information technology develops fast nowadays, fields as electronic business, bank online, public security requires better reliability and approaches of ID authentication, so traditional ID authenticating approaches can no longer satisfy these requirements. Face features carried on person are not easy to falsify, and they won't change much by age. Compare with fingerprint, retina, iris, gene etc biologic recognition approaches, face recognition conforms to our habits, which is direct, friendly, and won't cause psychological obstacles.Face detection and recognition hardly brings any body damages and restrictions. Face detection and recognition consists of face detection and face identification. Face detection gets the location and size of faces in input image. Face identification analyzes and extracts features from the face image. Its purpose is to make use of features to authenticate the identity. Face identification technology involves psychology, physiology, AI, pattern recognition, computer vision, image analysis and processing fields. Especially, it's basic revealing of human intelligence. It's the most typical and difficult pattern recognition. The research and solving of this problem do benefits other object recognition problems. So face recognition of great theoretical research value becomes one of the important subjects of such basic research. Main work and contribution to face detection and recognition of this paper...
