Face recognition is a biometric identification technology based on face feature information. A series of related technologies, usually called portrait recognition and face recognition, are used to collect images or video streams containing faces, automatically detect and track faces in images, and then recognize the detected faces.

Development history:

The research of face recognition system began in 1960s, and was improved with the development of computer technology and optical imaging technology after 1980s, but it really entered the primary application stage in the late 1990s, which was mainly realized by technologies from the United States, Germany and Japan.

The key to the success of face recognition system lies in whether it has the most advanced core algorithm and makes the recognition result have practical recognition rate and speed; "Face recognition system" integrates artificial intelligence, machine recognition, machine learning, model theory, expert system, video image processing and other professional technologies.

At the same time, it is necessary to combine the latest application of biometrics-the theory and implementation of median processing. The realization of its core technology shows the transformation from weak artificial intelligence to strong artificial intelligence.
