Abstract

The invention discloses a face authentication method and device and belongs to the field of image processing and mode identification. The method comprises the steps of: obtaining face image sample pairs; carrying out blocking on the obtained face image sample pairs; calculating local gray scale characteristic vectors and local direction gradient histogram HOG vectors of obtained blocks; and according to the calculated local gray scale characteristic vectors and local direction gradient histogram HOG vectors, calculating and judging whether the face image sample pairs belong to one person. By adopting the face authentication method and device, the interference of factors such as illumination, expression and age is effectively avoided, and simultaneously, the accuracy of face authentication is substantially improved.

Description

technical field

[0001] The invention relates to the field of image processing and pattern recognition, in particular to a face authentication method and device. Background technique

[0002] As people pay more attention to the security and concealment of information, identity authentication technology becomes more and more important. Traditional identity authentication methods, such as ID cards and passwords, are cumbersome to use, and the biggest shortcoming is that they cannot distinguish between the owner and the imposter. Biological characteristics are inherent to human beings, and are unique and difficult to replicate. Therefore, research on biometric recognition is of great significance. Among them, the advantages of face recognition include: no need for user cooperation; non-contact characteristics; simple implementation of equipment; and traceability. Due to the above advantages of face recognition, this technology has a wide range of application scenarios. In soci...
