Embodiment Construction

[0016] Combine below Figure 1 to Figure 3 Shown, the present invention is described in further detail.

[0017] Such as figure 1 As shown, the present embodiment discloses a face recognition method based on information fusion, the method includes the following steps S1 to S4:

[0018] S1. Obtain complex data information of the face image according to the depth information and grayscale information of the face image;

[0019] S2. Dimensionality reduction of the training set X composed of complex data information of human face images into a corresponding low-dimensional subspace training set, wherein there are m face images of people in the training set X, and each person has n face images ;

[0020] S3. Dimensionality reduction of complex data information of the face image to be tested to a low-dimensional subspace of the same dimension as the training set X;

[0021] S4. In the low-dimensional subspace, use the k-nearest neighbor method to identify the face image to be te...

Abstract

The invention discloses a method for recognizing human faces on the basis of information fusion, and belongs to the field of technologies for recognizing computer patterns. The method includes acquiring complex data information of human face images according to depth information and gray information of the human face images; representing training sets X in low-dimension subspaces; reducing dimensions for to-be-tested human face images until the to-be-tested human face images are in low-dimension subspaces identical to the low-dimension subspaces of the training sets X and then recognizing the human faces in the low-dimension subspaces by the aid of k nearest neighbor processes. The training sets X comprise the complex data information of the human face images, each training set comprises the corresponding human face images of m persons, and each person has n corresponding human face images. The method has the advantages that the depth information and the gray information of the human face images are fused to obtain the complex data information of the human faces, then the dimensions of the complex data information of the human faces are reduced until the complex data information can be represented in the low-dimension subspaces, the human faces are recognized in the low-dimension subspaces, and accordingly the human face recognition accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of computer pattern recognition, in particular to a face recognition method based on information fusion. Background technique [0002] With the rapid development of computer technology and biomedical engineering technology, the use of human biometrics for identity authentication and identification has become the preferred method of security verification. With its advantages of non-contact, non-infringement and non-exclusion, face recognition technology has become one of the most potential and most popular identification methods in biometric technology. [0003] Existing face recognition methods use image acquisition equipment to collect and recognize face information, but due to the limitations of image acquisition equipment, grayscale or color images are generally used for recognition processing. However, in the process of processing, since the brightness image is easily affected by factors such as light, ...
