Abstract

The invention discloses a face recognition method. The method comprises: 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; The image and the face image to be recognized are respectively subjected to circular symmetric Gabor transformation, superposition, regional energy extraction, and local binary mode transformation, corresponding to obtain a sample histogram containing texture information of the sample face image and a sample histogram containing the to-be-recognized face image. Recognizing the histogram to be identified of the texture information of the face image; comparing the sample histogram with the histogram to be identified to obtain the same face in the sample face image as the face image to be identified image. The invention also discloses a face recognition device. The invention reduces the calculation amount in the process of face recognition, shortens the calculation time and improves the efficiency of face recognition.

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 (Gabor Transform, Gabor Transform) and LBP (Local Binary Pattern, 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 transfor...
