Embodiment 1

[0034] like figure 1 Shown, a kind of embodiment one of the bimodal face authentication method with living body detection function, comprises the following steps:

[0035] A. Establish a database 101 storing visible light training images and near-infrared training images of faces with known identities;

[0036] B1. Simultaneously collect visible light images and near-infrared images of the head of the person to be authenticated through the image collection module 102;

[0037] B2. Judging whether the human face can be detected from the visible light image and the near-infrared image simultaneously by the human face detection module, if not, return to the step B1, and if it is possible, the human face area in the visible light image Intercept it as "visible light image of human face", and intercept the human face area in the near-infrared image as "near-infrared image of human face", and proceed to the next step;

[0038] C1. Perform histogram equalization on the human face v...

Embodiment 2

[0056] like image 3 As shown, a second embodiment of a dual-mode face authentication method with a living body detection function may further comprise the steps:

[0057] A. Establish a database 101 storing visible light training images and near-infrared training images of faces with known identities;

[0058] B1. Simultaneously collect visible light images and near-infrared images of the head of the person to be authenticated through the image collection module 102;

[0059] B2. Judging whether the human face can be detected from the visible light image and the near-infrared image simultaneously by the human face detection module, if not, return to the step B1, and if it is possible, the human face area in the visible light image Intercept it as "visible light image of human face", and intercept the human face area in the near-infrared image as "near-infrared image of human face", and proceed to the next step;

[0060] C1. Perform histogram equalization on the human face v...

Abstract

The invention relates to data identification, in particular to a bimodal face authentication method with a living body detection function and a system. The authentication method of the invention comprises the following steps: A. establishing a database of visible light training images and near-infrared training images of known faces; and B. simultaneously collecting visible light images and near-infrared images of the heads of people to be authenticated. The invention also provides a bimodal face authentication system with a living body detection function. The invention has the beneficial effects that combined identification with the bimodal characteristics of face near-infrared images and face visible light images is adopted, as a result, the identification and authentication accuracy is improved, identification failure in the case of major changes of faces is avoided; and in addition, a living body detection module is utilized to effectively prevent personators from using photos or models to deceive others.

Description

technical field [0001] The invention relates to data identification, in particular to a dual-mode face authentication method and system with a living body detection function in data identification. Background technique [0002] At present, the existing face authentication systems based on visible light are difficult to achieve good face authentication performance due to the influence of illumination changes. Although the near-infrared-based face authentication system proposed in recent years can partially overcome the influence of illumination changes, but when the recognition time is long from the face registration time, due to the large changes in the face (such as fat and thin faces) In the case of large changes), the system will generally fail to identify. In addition, since the existing face authentication system does not propose a living face detection scheme, it is vulnerable to being deceived by using a face model or photo, that is, stealing a registered face image ...
