Abstract

The invention discloses a human face vivo detection method and device, a storage medium and a processor. The method comprises the steps of establishing a preset human face detection model, a preset human face recognition model and a preset vivo detection model; respectively training the preset human face detection model, the preset human face recognition model and the preset vivo detection model according to a human face vivo detection data set; respectively inputting a to-be-detected human face picture to the preset human face detection model which reaches the convergence state and the presethuman face recognition model which reaches the convergence state, so that a to-be-detected human face area picture, a human face identity feature corresponding to the to-be-detected human face area picture and a preset human face area picture corresponding to the human face identity feature are obtained; and respectively inputting the to-be-detected human face area picture and the preset human face area picture into two feature extraction branches of the preset vivo detection model which reaches the convergence state, so as to obtain a detection result of the to-be-detected human face picture. The technical problem of low detection precision in human face vivo detection in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of human face detection, in particular to a human face liveness detection method, device, storage medium and processor. Background technique [0002] With its strong advantages of non-contact, convenient and easy to use, and high precision, face detection has been widely used in finance, security and other fields. In order to ensure the safety of face detection, liveness detection technology uses video analysis, image data processing and other means to distinguish real faces from fake faces, effectively resisting malicious attacks of fake faces such as photos, videos, 3D models, and masks. [0003] According to the different input data, the existing living body detection technology can be divided into two categories: one is based on multi-frame pictures or video sequences to calculate, using interactive or non-interactive detection mode, by analyzing the actions in continuous multi-frame images information to...
