Face detection model generation and face detection method, device and equipment

Abstract

The embodiment of the invention provides a face detection method, device and equipment. The method comprises the following steps: determining an image group to be subjected to face detection; combining the extracted feature maps of the target images to obtain a first target feature map; performing feature extraction on the first target feature map to obtain a second target feature map, wherein thesecond feature map is composed of vectors of a plurality of preset dimensions; determining each anchor point area associated with the vector in a preset image group, and calculating an information group of each anchor point area according to the vector; determining a candidate face area of the image group according to the information group of each anchor point area associated with each vector inthe second feature map; and generating a face detection result (the face detection result comprises a face region in the image group and a living body detection result of the face region) of the imagegroup based on the feature region matched with the candidate face region in the first feature map, thereby achieving the purpose of realizing living body detection of the face while realizing face detection.

Description

technical field [0001] The present invention relates to the technical field of face detection, and more specifically, to a face detection model generation and face detection method, device and equipment. Background technique [0002] Biometric technology has come a long way since the last century. Technologies such as fingerprint recognition, iris recognition, voiceprint recognition, and face recognition are becoming more and more mature, and are gradually being applied to people's production and life. Among them, face recognition technology has become one of the most popular biometric recognition technologies due to its intuitive and easy-to-acquire data. [0003] For a long time, people have been concerned about the accuracy of face recognition technology, that is, whether it can recognize the same face in different shooting environments, and whether it can distinguish between two similar but different faces. different faces. However, in the process of practical applica...
