Problems solved by technology

However, due to the large number of bands in this technology and the inevitable correlation between adjacent bands, there is a certain degree of redundancy in the hyperspectral image data, and the large amount of data increases the pressure on the post-processing of the image.

Embodiment Construction

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the connection can be used for both fixing and circuit communication.

[0042] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", ...

Abstract

The invention discloses a living body face detection method and system. The method comprises the steps that S1, acquiring a depth image and a hyperspectral image of a target area; S2, analyzing the depth image, and detecting a face area in the depth image; if the human face is detected, positioning key feature points of the human face in a human face area in the depth image to obtain position information of the key feature points of the human face; and S3, according to the position information of the face key feature points in the depth image, extracting spectral information corresponding to the face key feature points in the hyperspectral image, performing living body detection, and judging whether the face key feature points are living bodies or not. The depth image and the hyperspectralimage are combined, living body detection can be completed without the need for a user to cooperatively execute corresponding actions, the experience effect is good, the detection time is saved, theimage processing calculation amount is reduced, and the living body face detection efficiency and accuracy are improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and system for detecting living human faces. Background technique [0002] With the development of e-commerce and other technologies, face-based identity verification has been widely used, such as face-swiping payment, face recognition unlocking and other functions have been widely used in people's daily life, greatly improving the convenience of people's lives sex. However, while face recognition technology has greatly improved the convenience of people's lives, its security issues have gradually been exposed, especially with the emergence of high-simulation masks, many criminals have caused visual deception through realistic camouflage to carry out A series of criminal acts have also caused attacks on ordinary face recognition systems. Therefore, the live face anti-counterfeiting technology has aroused widespread concern. [0003] In the relevant li...
