Principle and algorithm of face recognition

1. The principle of face recognition refers to judging whether there is a face image in a dynamic scene and a complex background, and separating this face image. Face recognition is a hot research field of computer technology, including face tracking detection, automatic adjustment of image magnification, infrared detection at night, automatic adjustment of exposure intensity and other technologies.

2. The core of face recognition technology is actually "local human feature analysis" and "graphic/neural recognition algorithm." This algorithm is a method of using various organs and characteristic parts of human face. Such as compare, judging and confirm that identification parameters formed by a plurality of data corresponding to geometric relation with all the original parameters in the database.

3. Face recognition is a software-level algorithm, which is used to verify or identify a person's identity by processing video frames or digital images, in which the person's face is visible.
