Embodiment 1

[0063] According to an embodiment of the present invention, a fast static living body detection method based on borders and flash points is provided, see figure 1 , including the following steps:

[0064] S1: Perform an edge extraction operation on the image to be detected to obtain an extracted edge image.

[0065] In this embodiment, the edge extraction operation is used to reflect significant changes in the image properties to be detected through important events and changes in the properties in the image, such as discontinuity in depth, discontinuity in surface direction, material property changes or scene Illumination changes, etc., can be understood as being used to identify points with obvious brightness changes in the image to be detected, so as to effectively eliminate irrelevant information in the image, and retain important structural attributes in the image, so as to achieve accurate positioning of points with obvious brightness changes in the image , that is, to ...

Embodiment 2

[0137] According to another embodiment of the present invention, a fast static living body detection device based on frame and flash points is provided, see Figure 5 ,include:

[0138] The edge extraction module 51 is used to perform an edge extraction operation on the image to be detected to obtain an extracted edge image;

[0139] In this embodiment, the edge extraction operation is used to reflect significant changes in the image properties to be detected through important events and changes in the properties in the image, such as discontinuity in depth, discontinuity in surface direction, material property changes or scene Illumination changes, etc., can be understood as being used to identify points with obvious brightness changes in the image to be detected, so as to effectively eliminate irrelevant information in the image, and retain important structural attributes in the image, so as to achieve accurate positioning of points with obvious brightness changes in the ima...

Abstract

The invention relates to the technical field of image recognition, in particular to a quick static living body detection method and device based on a frame and flash points. According to the method and the device, the method comprises the steps: carrying out the edge extraction operation on a to-be-detected image to obtain an extracted edge image; performing frame detection on the edge image to obtain a first detection result; if the first detection result is that the frame is detected, taking an object in the to-be-detected image as a non-living body; if the first detection result shows thatthe frame is not detected, carrying out flashing point contour detection on the to-be-detected image of which the frame is not detected to obtain a second detection result; if the second detection result shows that the flashing point is not detected, determining the object in the to-be-detected image as a living body; if the second detection result is that the flashing point is detected, determining the object corresponding to the flashing point as the living body. According to the quick static living body detection method and device based on the frame and the flashing point, the living body identification efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of image recognition, in particular to a fast static living body detection method and device based on frames and flash points. Background technique [0002] With the development of modern image processing technology, the space for image modification is also increasing. People are increasingly required to verify the authenticity of image data in daily business operations. However, most of the existing living body detection technologies are aimed at the human body, and have no impact on participants. Liveness detection personnel require a high degree of cooperation, such as blinking, nodding, reading verification codes, etc., need to go through a series of complicated and interactive liveness detection methods to make the accuracy of liveness detection higher, and some comparisons will still be made during the detection process. Complicated detection of obviously non-living images is complex, time-cons...
