Definition: face recognition


Distinguishing the identity of people by their facial characteristics. The most advanced technology is based on the Eigenface algorithm, which maps the characteristics of a person's face into a multidimensional face space. Computers can conduct facial database searches and/or perform live, one-to-one or one-to-many verifications with unprecedented accuracy and split-second processing. Users can be granted secure access to their computer, mobile devices, or for online e-commerce, simply by looking into their Web camera.

Even With a Change of Appearance
The computer can distinguish the same person with or without glasses, change of hair style and seasonal skin color changes. Neural networks were used for earlier face recognition systems, but with Eigenface, the computer cannot be easily fooled by photographs or by someone else who looks similar. See iris recognition, information security and biometrics.

A face is digitized and matched against the face database to determine if the person is authorized to enter a facility or use a system. (Image courtesy of Miros, Inc.)






Face Surveillance
Cognitec's FaceVACS-VideoScan software tracks multiple faces simultaneously as they walk by. The system provides essential statistics such as people flow, visitor demographics and behavior. It even determines each person's approximate age.
