Problems solved by technology

However, these methods either randomly select features, discard some features, and lose effective features. Moreover, PCA is a method based on data representation and is not designed for classification problems. In short, PCA dimensionality reduction The latter features are not the most effective features for classif

Abstract

The invention provides a face recognition method. The method includes the steps of dividing a pretreated face sample image in fixed size into a plurality of superposed sub-regions in different sizes, extracting texture characteristics of the sub-regions, selecting the effective texture characteristics according to the preset rules, obtaining projection characteristic values of the effective texture characteristics, and carrying out face recognition according to the projection characteristic values of the sub-regions. The invention can improve the processing speed and the recognizing effect offace recognition.

Description

technical field [0001] The invention relates to the technical field of pattern recognition, in particular to a face recognition method and a face recognition system. Background technique [0002] The identity authentication technology based on biometric features has an increasingly important position and role in social life. Among a variety of biometric authentication methods, recognition and authentication based on human facial features have received widespread attention and attention due to their advantages of non-invasiveness, low cost, good concealment, and no need for special cooperation from the subject, and have a wide range of applications. prospect. [0003] In terms of functions, face recognition can be divided into two types: face recognition (FaceIdentification) and face verification (FaceVerification). Face recognition refers to comparing one or more face images to be identified with the face images of all people stored in the database, determining the most si...
