A method, related device, equipment and storage medium for face liveness detection

Abstract

The present application discloses a method for face liveness detection, which is applied in the field of artificial intelligence. The method provided by the present application includes acquiring an initial face image and a set of face images corresponding to N illumination directions; face image collection, obtain N differential images; generate normal map and reflectivity map according to N differential images and the N illumination directions; determine face liveness detection according to N differential images, normal map and reflectivity map result. The present application also discloses a related apparatus, equipment and storage medium. Since the present application simultaneously considers the three-dimensional geometric information and surface material information of the face image, the authenticity of the face image can be identified, and different face living body attack methods can be effectively resisted.

Description

technical field

[0001] The present application relates to the field of artificial intelligence, and in particular, to a method, related apparatus, equipment and storage medium for face liveness detection. Background technique

[0002] The main purpose of face liveness detection is to determine whether the current face is a real living person, so as to resist the attack of fake faces. Face liveness detection is an important step before face recognition. With the application of face recognition in many important fields such as face payment and face access control, the problem of using counterfeit faces to attack face recognition has become increasingly prominent. Face liveness detection is the main technical path to resist counterfeit face attacks.

[0003] At present, multiple face images are mainly used as the basis for face living detection. For example, if the face in the face image meets the action characteristics such as blinking or opening the mouth, the face in the im...

Examples

Embodiment Construction

[0099] The embodiments of the present application provide a method, related apparatus, equipment, and storage medium for face liveness detection, which can use incident light in different directions to illuminate the face, calculate the normal map and reflection map of the face image, and consider the human face at the same time. The three-dimensional geometric information and surface material information of the face image can be used to identify the authenticity of the face image and effectively resist different face living attack methods.

[0100] The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It is to be understood that data so used may be interchanged under appropriate circumstances such that the embodiments of the application described herein can, for example, be pra...
