Abstract

The invention discloses a face silence living body detection method and device, a computer readable storage medium and equipment, and belongs to the field of face recognition. The method comprises thefollowing steps: training a pre-constructed classification model; acquiring a face image to be subjected to living body detection and preprocessing the face image; and inputting the preprocessed faceimage into a classification model to obtain a living body detection result, wherein the classification model comprises a plurality of layers of convolutional neural networks; each convolutional neural network in the previous layer corresponds to two convolutional neural networks in the next layer; wherein the convolutional neural network of the previous layer can classify the face image into a living body type and a prosthesis type, and the convolutional neural network of the next layer further classifies the result (especially the result of wrong classification) of the convolutional neural network of the previous layer after classification. And so on, the classification result of the last layer of convolutional neural network is the living body detection result. The face silence living body detection method does not need user cooperation, and is good in user experience, high in speed and accurate in classification.

Description

technical field [0001] The present invention relates to the field of face recognition, in particular to a method, device, computer-readable storage medium and device for silent face detection. Background technique [0002] With the application of face recognition systems in finance, security and other fields, such as face payment, face unlocking, etc., more and more problems of face prosthesis attacks appear. The face prosthesis attack mainly refers to the use of a prosthetic face to attack the face recognition system, so as to deceive the system and obtain relevant permissions. There are three main types of prosthetic faces, namely printed prostheses, screen prostheses and 3D mask prostheses. The printed prosthesis refers to the result of reprinting the face after printing on paper, the screen prosthesis refers to the remake of the video image or picture displayed on the electronic screen to obtain the prosthesis image, and the 3D mask prosthesis refers to It is an image ...
