3D Face Feature Processing and Recognition Technology

Abstract Nowadays, we frequently use a lot of biometric identification technology means, such as: iris recognition, voice recognition and face but compared with other human features, information is easier to collect more easily accepted by the public. According survey, in interpersonal contact, most people get based on first impression, even if there are changes external conditions as age, expression, makeup, etc., brain can still recognize these information, this phenomenon shows that does have feature information. From person's facial effectively distinguish each person. Face analyzes data then uses it an authentication mechanism. Generally, cameras used track faces, model theory analyze collected binary stream extract relevant data. The research began middle 1960s. After 1980s, due development computer improvement optical image processing technology, gradually matured. real stage late 1990s, Germany, Japan United States main technologies.
