Abstract

The invention discloses a face recognition method, device and system and a model training method and device, and belongs to the technical field of face recognition. The method comprises the steps of inputting a to-be-identified face image to a deep learning model; receiving face feature data output by the deep learning model; in the deep learning model, the input layer is used for carrying out data processing on a to-be-identified face image after receiving the to-be-identified face image so as to obtain high-dimensional feature data; the first output layer is used for performing data dimension reduction processing on the high-dimensional feature data to obtain low-dimensional feature data; the feature combination layer is used for preprocessing the low-dimensional feature data and carrying out merging processing on the low-dimensional feature data to obtain combined feature data; and the second output layer is used for carrying out feature fusion on the combined feature data to obtainface feature data. The problems that in the prior art, the face recognition efficiency is low, resource and time consumption is large when a deep learning model is trained, and the training flexibility is low are solved.

Description

technical field [0001] The present invention relates to the technical field of face recognition, in particular to a face recognition method, device and system, and a model training method and device. Background technique [0002] Face recognition technology is a technology that extracts facial features through computers and performs identity verification based on these facial features. Faces are born with other biological characteristics (such as fingerprints, irises, etc.) of the human body. Their uniqueness and good characteristics that are not easy to be copied provide the necessary conditions for identification. Compared with other biometric recognition technologies In contrast, face recognition technology has the characteristics of simple operation and intuitive results. At present, in order to improve the accuracy of face recognition, a trained deep learning model is usually used to extract face features. [0003] In related technologies, it is usually necessary to t...
