Abstract

The invention provides a face recognition method and face recognition equipment. The method comprises the following steps of: performing down-sampling on an original face image to obtain down-sampled images with different sizes; blocking the down-sampled images and the original face image; performing characteristic extraction on each image block obtained by blocking; performing similarity matching on characteristics of each extracted image block and characteristics of the corresponding image block of a pre-registered face image to obtain the similarity of each image block; and obtaining a recognition result of the face image according to the obtained similarities of all the image blocks. According to the face recognition method and the face recognition equipment, the original face image is subjected to down-sampling to obtain the down-sampled images with different sizes for multi-size face image characteristic extraction, so that the capability of the characteristics of the face image in the description of the image face is improved; and the down-sampled images and the original face image are blocked, and the recognition result of the face image is obtained according to the obtained similarities of all the image blocks, so that the recognition accuracy of the face image is improved.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a face recognition method and device. Background technique [0002] Today, with the rapid development of electronic information technology, e-commerce, online banking, public security and other fields have put forward new requirements for the reliability and methods of identity authentication. Biometrics is an inherent attribute of human beings, which has strong self-stability and individual differences. Therefore, the use of biometrics for identity authentication has attracted more and more attention. Among them, the use of face features for identity authentication is the most natural and direct means. Therefore, in-depth research on face recognition technology has important application value. Feature extraction is the core issue of face recognition technology, which is directly related to the accuracy of final face recognition. [0003] In the prior art, a number...
