Abstract

The invention discloses a silent human face living detection method and device, a storage medium and a processor. The method comprises the following steps: training a preset face detection model and apreset overall face feature model according to a preset face picture data set; training the preset face region feature model according to the preset face picture data set and the preset face detection model reaching the convergence state; the preset face detection model, the preset global face feature model and the preset face region feature model are cascaded to obtain the living body detectionmodel; training the living body detection model according to the preset face picture data set; according to the convergent state of the living detection model to be detected face image detection, obtaining the detection results. The invention solves the technical problem that the detection efficiency of the human face living body detection in the prior art is low.

Description

technical field [0001] The present invention relates to the field of face recognition, in particular to a silent face detection method, device, storage medium and processor. Background technique [0002] In recent years, with the development of deep learning and computer vision technology, the performance of face recognition has surpassed the human level, and it has been widely used in actual scenarios with its ultra-high recognition accuracy, such as facial recognition-based payment, access control, etc. , face attendance machine, etc. Face recognition has the characteristics of non-contact, convenient and easy to use. However, forged faces such as photos, videos, masks, and 3D models have brought great security risks to face recognition. In order to prevent security attacks, live body detection technology has emerged as the times require. Through a variety of technical means, real faces can be distinguished from fake faces to ensure information security. [0003] Existin...
