Abstract

The invention discloses an improved Resnet-based human face in-vivo detection method and related equipment, and relates to the field of in-vivo detection, and the method comprises the steps: obtaininga to-be-detected single-frame image containing a human face image; for each face image in the to-be-detected single-frame image, based on an improved Resnet, obtaining a probability value of the faceimage directly coming from a living body; and judging whether the face image is directly from a living body based on a matching result of the probability value and a preset threshold value. Accordingto the method, the accuracy of human face in-vivo detection is improved.

Description

technical field [0001] The invention relates to the field of living body detection, in particular to a method for face living body detection based on an improved Resnet and related equipment. Background technique [0002] Today, with the rapid development of Internet technology, the application of face recognition is more and more closely related to life, such as: access control system, face payment, etc. In these scenarios, in addition to being able to recognize human faces, it is also necessary to judge the authenticity of human faces to prevent malicious people from using other people's photos and videos to carry out illegal activities. For the authenticity judgment of human faces, that is, liveness detection. [0003] In the existing living body detection technology, most rely on temperature sensing hardware, such as: infrared sensor. The temperature sensing hardware is used to determine whether the currently acquired video is directly from a living body. The disadvan...
