Abstract

The invention is suitable for the technical field of computers, and provides a face recognition method and device, and the method comprises the steps: obtaining the target face information of a targetface of a to-be-recognized user; wherein the target face information comprises target face attribute information and target face feature information; determining a human face sub-database corresponding to the target human face based on the target human face attribute information, a preset human face database and a preset search strategy; and traversing the face sub-database based on the target face feature information, and when a similarity value between the face feature information of the first face and the target face feature information meets a preset condition, identifying the identity information corresponding to the first face as the identity information of the to-be-identified user. According to the scheme, the face recognition database is subdivided based on the face attribute information, and the target face is directly recognized in the sub-library, so that the search performance is greatly improved, the query range is reduced, the workload is reduced, and the recognition speed is increased.

Description

Technical field [0001] The invention belongs to the field of computer technology, and particularly relates to a face recognition method and equipment. Background technique [0002] Face recognition is a kind of biometric recognition technology based on human facial feature information. A series of related technologies that use a camera or camera to collect images or video streams containing human faces, and automatically detect and track human faces in the images, and then perform facial recognition on the detected faces, usually also called face recognition and facial recognition . The current face recognition method is mainly to compare one by one in the feature comparison library, and recognize the face to be recognized in the database. Once the database is too large, the recognition speed of this method will be very low. [0003] At present, in order to improve the speed of face recognition, clustering is usually used to classify a large amount of data in the database. Faces...
