Face anti-cheating method and device, computer equipment and storage medium

Abstract

The invention relates to the field of artificial intelligence, and discloses a face anti-cheating method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a plurality of infrared images and a plurality of color images of a to-be-recognized figure in the same time interval; extracting infrared image features of the to-be-recognized figure from the infrared image; extracting color image features of the to-be-recognized figure from the color image; calculating a plurality of inter-frame optical flow features of the plurality of color images; fusing the infrared image features, the color image features and the inter-frame optical flow features to obtain fused features; and inputting the fusion feature into a preset classifier for processing, and outputting a classification result that the face of the to-be-recognized figure is a living face or a cheating face. According to the invention, whether the face of the to-be-recognized figure is a living face or a cheating face can be comprehensively judged, the recognition accuracy is high, and the consumed time is short. In addition, the scheme can be applied to the fields of smart cities, smart education and the like, and the construction of the smart cities or the smart education is promoted.

Description

technical field [0001] The present invention relates to the field of artificial intelligence, in particular to a face anti-cheating method, device, computer equipment and storage medium. Background technique [0002] With the continuous development of Internet technology, video surveillance has been widely used in various fields. Numerous video surveillance applications urgently need a fast face recognition technology in the long-distance and non-cooperative state of the user, in order to quickly and accurately confirm the identity of the person at a long distance and realize intelligent early warning. In order to improve the accuracy and security of face recognition, face anti-cheating technology came into being. Face anti-cheating is a technology applied in face recognition scenarios to prevent impersonation of other people's faces. Usually, the act of impersonating someone else's face is to use a mobile phone, tablet, printed paper, etc., to show a photo or video of som...
