Face recognition method technology overview

Emerging - Face Recognition Face recognition technology in China is the most gorgeous debut of the 2008 Beijing Olympic Games. The opening and closing ceremonies of the Beijing Olympic Games will be subject to real-name management. Ticket holders are required to submit personal information and identity photographs in advance, and use face recognition technology for real-name authentication when the audience enters the venue to eliminate potential security loopholes. Improving the level of Olympics safety precautions and anti-terrorism technology, this is the first time in the history of the Olympics to use face recognition technology as an intelligent means of personal identification to introduce Olympic security.

After the face recognition system was formally used at the opening ceremony of the Beijing Olympics, the face recognition technology has received extensive attention in the country and has been promoted in applications such as access control and attendance.

Face Recognition Technology Overview Face recognition is based on human facial features. For the input face image or video stream, first identify the characteristics of each part of the face, the position information of each major facial organ, and based on these information, further extraction Biometrics contained in human faces are compared with stored face templates to identify people.

Facial recognition algorithm is widely used in face recognition technology. It integrates computer image processing technology and biostatistics principles. It uses computer image processing technology to extract portrait feature points from video and uses biometrics. The principle of learning is analyzed to establish a mathematical model, namely a face feature template. Using the established face feature template and the subject's face image for feature analysis, a similar value is given based on the results of the analysis. Through this value, it can be determined whether the same person.
