Introduction To Face Recognition Technology

- Sep 17, 2019-

Face recognition technology is based on human face features to input face image or video stream. Firstly, determine whether there is a face, and if there is a face, further provide the location, size of each face and the location information of each major facial organ. Based on this information, the identity features contained in each face are further extracted and compared with known faces to identify the identity of each face.

Generalized face recognition actually includes a series of related technologies to build a face recognition system, including face image acquisition, face positioning, face recognition preprocessing, identity confirmation and identity search, etc. In the narrow sense, face recognition refers to the technology or system of identity confirmation or identity search through face.

Biometric identification technology research of biological characteristics including hand face, fingerprint, palmprint, iris, retina, sound (voice), the bodily form, personal habits, such as the strength and frequency of the keyboard, signature), and so on, the corresponding recognition technology has the face recognition, fingerprint recognition, palmprint recognition, iris recognition, retina recognition, speech recognition (with speech recognition can be identification, also can undertake speech content recognition, only the former belongs to the biometric identification technology), shape recognition, keystrokes recognition, signature recognition, etc.
