Abstract

The invention relates to the technical field of image recognition, particularly provides a living body detection method, system and device and a medium, and aims to solve the problem of how to effectively carry out living body detection in a face recognition process so as to effectively defend attacks such as a living body injection attack and the like. In order to achieve the purpose, according to a coded face video which is subjected to color light coding and collected by image collection equipment, a face image is obtained, feature extraction is carried out on the face image, and video features of the coded face video are obtained, so that the probability that a face in the coded face video is a real face is obtained. According to the invention, whether the coded face video is a real face or not can be effectively detected according to the video features, various attack forms such as in-vivo injection attack and the like can be effectively defended, and the defending effect of in-vivo detection is improved.

Description

technical field [0001] The present invention relates to the technical field of image recognition, and in particular provides a method, system, device and medium for detecting a living body. Background technique [0002] In face recognition technology, liveness detection is a very important step, and liveness detection is the most common method to prevent face fraud. For the face picture captured by the camera, live detection can determine whether the face picture is a real face captured or a fake face (fake face includes face photos taken in advance, face videos, etc.). In the prior art, the most commonly used method of living body detection is 2D face living body detection, that is, it is judged by features such as moiré, screen reflection, face distortion, reflection, and screen paper frame to determine whether the face image captured by the current camera comes from It can also be judged by asking the user to do some cooperative actions, such as blinking, opening the mou...
