Abstract

The present invention discloses a human face identifying method and apparatus for solving the problems in the prior art that redundant information can be easily brought about in the characteristic extraction of a plurality of different characteristics through a parallel manner. The human face identifying method comprises: obtaining a human face image; conducting Gabor transform to the human face image to obtain a Gabor characteristic image; using the LBP algorithm to process the obtained Gabor characteristic image to obtain the first LBP histogram characteristics; using the LPQ algorithm to process the human face image to obtain the first LPQ histogram characteristics; and fusing the first LBP histogram characteristics and the first LPQ histogram characteristics according to a preset order as the obtained human face characteristics through identification. Compared with the prior art, in the human face identifying method featuring Gabor-LBP and LPQ serial-parallel fusion, complementary information is fully utilized and redundant information is reduced.

Description

technical field [0001] The invention relates to the technical fields of pattern recognition and digital image processing, in particular to a face recognition method and device. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information. [0003] At present, the processing process of a typical face recognition system is: obtain the face position in the image to be processed, and perform illumination processing, geometric normalization and other operations on the obtained face; Different feature extraction methods are used to extract a variety of different types of face feature vectors, and then dimensionality reduction is performed on the extracted different types of face feature vectors; various different types of face feature vectors after dimensionality reduction are calculated separately and the similarity between the face feature vectors to be compared, and then fuse the obtained similarities cor...
