Abstract

The invention discloses a face recognition method based on the combination of local features and global features. The face recognition method comprises the steps that first, faces in an existing face database are extracted to train a training set; second, a grayscale image of an input face is extracted; third, main component features of the input face are extracted and recognized; fourth, local binary features of the input face are extracted and recognized; fifth, the main component features and the local binary features of the input face are weighted; sixth, the face matched with the input face is searched for in the existing face training set and output. The face recognition method improves the recognition rate of face recognition, combines two types of algorithms, and is wide in application prospect.

Description

technical field [0001] The present invention relates to a method for face image recognition, specifically a face recognition method based on the weighted fusion of principal component analysis (PCA) global features and local binary pattern (LBP) features. Background technique [0002] In 1888, Calton published a paper on the principle of human identification of faces in "Nature", thus proposing face recognition technology. In the following 80 years, the direction of technology development is mainly to process the gray scale and brightness of the face pictures, and then use the naked eyes to perform face recognition. So far, face recognition technology has been widely used in security, video tagging, image database retrieval, general identity verification and intelligent human-computer interaction technology. At the same time, with the advent of the Internet age, large-scale face recognition based on the Internet has become a new research topic and application direction. ...
