Embodiment Construction

[0025] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0026] On the one hand, the present invention provides a face authentication method, such as figure 1 shown, including:

[0027] Step S101: Obtain a face image sample pair;

[0028] Face image sample pair: In the process of face authentication, the face image detected in real time is usually compared with the face image in the existing database 1:1. This process is called authentication, and in the comparison The two face images processed in the process (that is, including a real-time image and a library image) are called a face sample pair.

[0029] In this step, according to different usage environments, the image sample pair can be composed of face images collected in real time and face images stored in the database, or can be composed of two face i...

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...
