Method for human face recognition based on face geometrical features

Abstract

The invention provides a method for human face recognition based on face geometrical features. The method includes human face feature points detection, geometrical feature construction, human face database classification and human face recognition. According to the invention, the method, based on human face detection and human face recognition technology, improves geometrical features used in the human face feature point detection method and human face recognition, and guarantees in-time and accuracy of a human face recognition system based on feature point detection which combines an active shape model and the elastic bunch graph matching algorithm and also simple and accurate face geometrical feature technology. According to the invention, the method decomposes data in a large database into a plurality of sub-databases with labels which are determined by selected classification geometrical features. As for the input image to be tested, matching data can be reduced by simply comparing classification geometrical features of the image to be tested with each sub-database label in order to greatly increase efficiency of human face recognition.

Description

technical field [0001] The invention relates to a face recognition technology, in particular to a face recognition method based on facial geometric features. Background technique [0002] Face recognition technology is a pattern recognition technology that detects the face target object in the image and uses the face image feature information in the target object for identification. In recent years, with the attention and attention of government agencies, enterprises and personal information security , the application of face recognition technology has gradually entered the lives of ordinary people, and more and more technological innovation companies have also invested a lot of resources to participate in the research and development of face recognition. For example, the face recognition completed by Alibaba launched Payment verification. Compared with the traditional pattern recognition technology, face recognition has the advantages of non-contact and concealment, which ...
