Abstract

The invention relates to a method for identifying a face of a living body. The method for identifying the face of the living body comprises the following steps of (1) collecting the face image information; (2) generating at least one group of face image sequences from the face image information; (3) extracting the human face local features from the at least one group of human face image sequences;(4) screening out a low-dimensional feature vector of the face image information from the face local features; (5) inputting the low-dimensional feature vector into a trained classifier to carry outliving body face image recognition; and (6) outputting an identification result. Correspondingly, the invention further relates to a system for identifying the face of the living body. According to the method and the system provided by the invention, the face of the living body can be quickly and accurately identified, and the high requirement of the embedded equipment for the real-time performance can be met.

Description

technical field [0001] The invention relates to the field of machine vision, in particular to the recognition of biological features by machine vision, especially the recognition of living human faces. Specifically, the present invention relates to a method and corresponding system for recognizing living human faces. It is obvious to those skilled in the art that the present invention can also be applied in other fields. Background technique [0002] Face recognition has always been a research hotspot in the field of biometrics. It has extensive research in computer, (applied) mathematics, electronics, automation, visualization, virtual reality, image processing and pattern recognition. , Criminal investigation, entry-exit gate management, airport inspection and other fields have important application value. In recent years, face recognition technology has developed rapidly and has been widely used in many fields. [0003] In the application of face recognition system, li...
