Problems solved by technology

[0014] ① Most of the face recognition software in the existing technology can also pass the verification by using the photos of the registrants, and cannot distinguish whether it is a living person or a photo, which greatly reduces the security of face recognition
In low light, the positioning effect of ASM on the human eye and the edge detection effect of Canny on the human eye are not good.
[0016] ③Unable to recognize faces well under low-light conditions
[0017] ④ Existing algorithms do not have high face matching in different lighting environments

Abstract

The invention provides a human face recognition method based on blink detection. The method comprises the steps: taking a picture of a user through a camera, and detecting a human face image from the picture of the user through a human face detector; carrying out the matching of the human face image with a pre-stored registered human face image through a human face matching algorithm, and determining that the human face is registered when the similarity of the matching result is greater than a set matching threshold value; detecting whether a plurality of user images have the blink phenomenon or not through a blink detection algorithm, and determining that the user images are the images of a living body if the user images have the blink phenomenon. The method can detect whether the detected object is a picture, a sculpture or a living body well through blink detection. Compared with an ASM+Canny blind detection method which is higher in requirements for light, the method carries out the differential processing of the image through the morphology, and can be well suitable for a weak light detection condition.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a face recognition method based on blink detection. Background technique [0002] Face recognition technology is a popular computer application research technology, which belongs to biometric identification technology, and distinguishes individual organisms through the biological characteristics of the organism itself. Face recognition is the most natural and visual biological identification method, which is in line with human's own physiological visual habits. With the development of face recognition technology, the accuracy and reliability will be greatly improved. Now it has a very wide range of applications, including public security, security, customs, finance, military, airport, security and other important industries and fields, as well as civilian markets such as smart access control and time attendance. The market application prospect is very broad. [0003] F...
