A face recognition system for security access control, developed by Institute of Automation of the Chinese Academy of Sciences (CASIA), is used at Expo 2010 Shanghai.
Visitors to the Expo have to pass through the face recognition system that is linked to electronic locks before entering any important Expo site.
Differing from the face recognition system for identity verification at the Beijing Olympics, the face recognition system for the Expo 2010 is a kind of near infrared face recognition, which is the world’s first illumination independent one and has obtained several international patents.
According to Prof Stan Z.Li, a developer of the face recognition system from CASIA, near infrared face recognition technology can overcome the effects of illumination change and distinguishes itself by its recognition performance which has surpassed that of 3D face recognition in accuracy, stability and speed. It can complete the procedure of face feature extraction, comparison and identification in just seconds, effectively identify people without any complementary means, and decide whether to grant or deny an access request and keep a record of the access, said Stan Z.Li.
As the most natural and visualizable biometric recognition method, face recognition fits in with people’s practices and may be widely accepted by people, it therefore enjoys a promising market worldwide.
