Abstract

Embodiments of the present disclosure disclose methods and devices for detecting a living body. A specific embodiment of the method includes: extracting adjacent video frames from the video frame sequence corresponding to the target human face video as the first human face image and the second human face image; determining the human face from the first human face image The key point is used as the first key point of human face; the key point of human face corresponding to the key point of the first human face is determined as the key point of the second human face from the second human face image; based on the key point of the first human face and the second key point of human face The distance of the key points of the human face is used to generate a detection result indicating whether the human face corresponding to the target human face video is a live human face. This embodiment can improve the efficiency of living body detection; moreover, the living body detection based on the key points of human face helps to reduce the consumption of CPU in the process of living body detection.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of computer technology, and in particular to methods and devices for detecting living bodies. Background technique [0002] With the development of face recognition technology, people can already realize account login, payment, unlocking, etc. by "swiping face". This brings convenience to people's lives, but at the same time there are risks. Since the machine can recognize faces, of course it can also recognize face images. Therefore, there may be a risk that criminals use other people's face images to disguise their identities. [0003] At present, in order to reduce the above-mentioned risks, liveness detection is usually performed on the target face object. Contents of the invention [0004] Embodiments of the present disclosure propose methods and devices for detecting a living body. [0005] In the first aspect, the embodiment of the present disclosure provides a method for detecting ...
