Research And Implementation Of The Technology Of Automatic Human Face Recognition

With the development of society and the degree of society information improving rapidly, in all aspects the demand for effective automatic identity verification is increasingly urgent. The biological characteristics are the human inherent attributes, which have very strong stability and individual difference, so it is the most ideal basis of identity verification. Make use of the human face characteristics to carry on the identity verification is the most natural and direct means, Comparing with other the human biological characteristics it has direct, friendly and convenient characteristics, therefore automatic human face recognition becomes the research focus of the identity verification.Human face recognition technology has extensive application backgrounds. Automatic human face recognition system can be applied for criminal identity verification of public security system, check certificate photo with holder , such as driving license and passport ,etc, and the Monitoring system of bank and the customs and the automatic entrance guard systems etc. In addition, human face recognition technology has enormous potential application value in the field of information safety. Human face recognition technology can carry on security log-in controlling, application program using safely, database visiting safely and file encryption of the computer. It can also protect the security of e-commerce, and search the picture storehouse, searching the same as or close face among large-scale human face storehouse. After American is attacked by terrorists, this technology causes more extensive concern. As an easy concealing recognition technology, human face recognition nowadaysbecomes international anti-terrorism and one of the most important means of safe precaution. The main goal of this subject is realization of the automatic human face recognition system.The automatic human face recognition system includes face detection, feature extraction and face recognition, face location and face detection at first find human face and the position from inputting picture in face storehouse, cut apart human face from the background; Then human face picture in normalization carry on feature extraction. Effectively extracting recognition feature is the key of human face recognition; finally, carrying on the face recognition. To givingthe introduction picture which includes the human faces human face recognition technology is compared with and match known human face model that stored in the face storehouse, confirming whether it is one person in the storehouse or not, if yes, providing the best matching person in the storehouse can realize the purpose of human face recognition automatically.
