Biometrics: a look at face recognition / Loimih Ramidi

Biometrics are automated methods of recognizing a person based on a
physiological or behavioral characteristic. Biometric technologies are becoming
the foundation of an extensive array of highly secure identification and personal
verification solutions. Face authentication is a fairly young technology compared
to other biometrics. Research in this field has been going on for decades, but it
has been in the last 10 to 15 years that the greatest advances have taken place.
The analysis process over the years has moved away from using the simple
geometry of key facial points to the use of more complex mathematical
techniques.
