The development of face recognition

Face recognition is a kind of biometric identification technology based on the facial feature information of a person for identity authentication, and it mainly adopts a non-contact method for identification. The entire development process of face recognition can be divided into mechanical recognition, semi-automatic recognition, non-contact recognition and Internet application stages.

In the 1960s, some researchers began to study face recognition, and entered the primary stage in the late 1990s; in 1991, the Eigenface algorithm was applied to face recognition, and the automatic detection of faces was realized for the first time; After 2000, the NIST Research Institute extended the FERET project, launching two new projects FRVT and FRGC successively; in 2010, with the addition of face recognition function by Facebook, face recognition began to move towards individuals; in 2017, Apple iPhone X released the face unlock function for the first time and detonated the market, and now face recognition has been applied in all aspects
