Embodiment Construction

[0066] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0067] The invention provides a face recognition method.

[0068] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the face recognition method of the present invention.

[0069] In this embodiment, the face recognition method includes:

[0070] Step S10, acquiring a sample face image and a face image to be recognized, wherein there are at least two face images in the sample face image;

[0071] The terminal obtains a face image through a camera, and the face image obtained by the terminal includes a sample face image and a face image to be recognized, wherein there are at least two face images in the sample face image, and the face image to be recognized There is only one face image in the face image. In this embodiment, the sample face images include 11 face images. In order t...

Abstract

The invention discloses a face recognition method, comprising following steps: sample face images and face images to be recognized are obtained, wherein the sample face images contains at least two face images; circularly symmetrical Gabor transform, superposition, local energy extraction, and local binary pattern conversion are performed to the sample face images and the face images to be recognized to obtain sample histograms containing texture information of the sample face images and histograms to be recognized containing texture information of the face images to be recognized; the sample histograms are compared with the histograms to be recognized to obtain face images in the sample face images which are the same with the face images to be recognized. The invention also discloses a face recognition device. By use of the method and device, the calculation quantity in a face recognition process is reduced, the calculation time is shortened, and face recognition efficiency is increased.

Description

technical field [0001] The invention relates to the field of multimedia, in particular to a face recognition method and device. Background technique [0002] In the process of face recognition, it is necessary to extract face texture information from the face image. The traditional face texture information extraction method uses GT (GaborTransform, Gabor Transform) and LBP (LocalBinaryPattern, local binary pattern) transformation for superimposition, thereby extracting face texture information. The specific process is: firstly, the face image is filtered by Gabor, and then the filtered image is transformed by LBP histogram to represent the texture information of the face. Then, the face image needs to be transformed in 5 scales and 8 directions to generate 40 images. Filter the images, and then perform LBP transformation processing on the 40 filtered images, and finally perform face recognition. In the process of using the combination of Gabor transform and LBP transform t...
