Embodiment Construction

[0050] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

[0051] For various types of attacks such as print photo attacks, screen playback attacks, and high-definition 3D attacks, traditional face live detection methods based on artificial feature extraction or simple feature classification are often difficult to perform accurate face live detection, which will lead to face recognition The system cannot provide effective defense. Especially when it is "attacked" by an unknown medium, it is very easy to fail....

Abstract

The embodiment of the invention provides a human face living body detection method and device, computer equipment and a storage medium. The method comprises the steps: acquiring a human face image collected by shooting equipment; inputting the face image into a feature extraction network obtained by training in combination with a metric learning device for processing to obtain a first feature vector; inputting the first feature vector into a feature classification network obtained by training in combination with a classification learner for processing to obtain a second feature vector and a living body prediction value; and determining the living body detection result of the face image according to the second feature vector, the living body prediction value and the intra-class center position of the living body feature vector. Through the embodiment of the invention, the accuracy of human face living body detection can be effectively improved.

Description

Technical field [0001] This application relates to the field of artificial intelligence technology, and in particular to a method for detecting live human faces, a device for detecting live human faces, a computer device and a computer-readable storage medium. Background technique [0002] With the development of artificial intelligence technology, especially the development of biometric technology, face recognition technology has been widely used in people's daily life, for example, it can be used in scenarios such as gate-passing, payment, and verification. In various application scenarios of face recognition technology, computer vision tasks based on face images will encounter various "attacks". New types of attacks emerge in endlessly. Common attack methods include various printing photos (including color printing photos, black and white printing photos, infrared printing photos, etc.) attacks, screen (including mobile phone screens, tablet screens, computer screens, etc.) pl...
