Principle of face recognition system:
1. The principle of mobile phone face recognition is to capture images or video streams containing faces with a camera, and automatically detect and track the faces in the images, so as to identify the detected faces.
2. The research of face recognition system began in 1960s. Since 1980s, with the development of computer technology and optical imaging technology, the face recognition system has been continuously improved. But it really entered the initial application stage in the late 1990s, mainly in the United States, Germany and Japan.
3. The key to the success of face recognition system lies in whether there is an advanced core algorithm to make the recognition result have actual recognition rate and speed; "Face recognition system" integrates artificial intelligence, machine recognition, machine learning and other professional technologies.
At the same time, it is necessary to combine the latest application of biometric identification-the theory and implementation of median processing, and the realization of its core technology reflects the transformation from weak artificial intelligence to strong artificial intelligence.
Extended data:
First, the advantages of face recognition:
It lies in its naturalness and the characteristics that are not perceived by the tested individuals. The so-called nature means that the identification method is the same as the biological characteristics used by human beings (even other creatures) in individual identification. For example, in face recognition, human beings also distinguish and confirm their identities by observing and comparing faces.
In addition, there are speech recognition, graphic recognition and so on. Fingerprint recognition and iris recognition are not innate, because humans or other creatures do not distinguish individuals through such biological characteristics.
Second, face recognition is difficult:
Face recognition is considered to be one of the most difficult research topics in the field of biometric identification and even artificial intelligence. The difficulty of face recognition is mainly caused by the characteristics of face as a biological feature.
