The Shortcomings of Face Recognition Technology —— Face Recognition Rate

Face recognition technology belongs to biometric identification technology, which distinguishes biological individuals through their own biological characteristics. Face recognition technology refers to the use of computer technology to recognize faces.

"The existing face recognition system can achieve satisfactory results with the cooperation of users and ideal acquisition conditions. However, in the case of uncooperative users and unsatisfactory acquisition conditions, the recognition rate of the existing system will drop sharply. Face recognition technology is far from being practical, and there are still many challenging problems to be solved. " Tan Xiaoyang introduced this in an interview with Beijing Youth Daily.

For example, when comparing faces, it is different from the faces stored in the system. For example, shaving the beard, changing the hairstyle, adding more glasses and changing the expression may all lead to the failure of comparison. In other words, if the person changes slightly, the system may fail to authenticate. Today, it is conservatively estimated that the accuracy of face recognition technology can reach 95%, but it has not reached 100%. At the same time, for twins, face recognition is basically impossible because of too many similar features.

Zhang Xiaobo, Ph.D., Institute of Automation, Chinese Academy of Sciences, also believes that lighting, posture and decoration have an impact on face recognition by machines. At present, the United States has the most advanced face recognition system in the world, and the misreading rate during the test is also 1%.
