Abstract

The invention provides a face action matching type living body verification method for a real-time video stream, and the method comprises the following steps: selecting a target guide action, and obtaining a guide action preset process state and a guide action final state of the target guide action; starting a face detection and tracking process; and in the face detection and tracking process, judging the preset process state of the guide action and the final state of the guide action. The invention provides a real-time video stream face action matching type living body verification method, which comprises the following steps: on one hand, carrying out face detection and tracking; on the other hand, carrying out guiding action matching, fusing face detection and tracking with guiding action matching, and if the tracking process is interrupted, carrying out judgment again; besides, during guiding action matching, adding process judgment from an initial state to a target state of the guiding action, so that the purpose of living body verification cheating is achieved by comprehensively and effectively preventing a mode of switching a static picture and a static model, and the accuracy of living body verification is improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent video image processing, and in particular relates to a real-time video stream face-action-cooperating living body verification method. Background technique [0002] The camera cooperates with the face recognition system to realize personnel identity verification, such as for access control, registration and other scenarios. At present, in order to prevent deception caused by static photos and static character molds, the biometric verification method is adopted. The living body recognition verification method refers to: cooperate with the face recognition algorithm to guide the verified person to complete the preset actions such as blinking and opening the mouth. Image recognition is performed on multiple image frames, and it is judged whether the actions completed by the verified person match the preset actions, so as to determine whether the verified person is alive. [0003] The above meth...
