Abstract

The invention discloses a face recognition method and system based on a dynamic threshold, and a storage medium, and the method comprises the steps of obtaining a to-be-recognized face image, and calculating a feature vector of the to-be-recognized face image; enabling the feature vector of the face to approach to the direction of the feature center by utilizing an updating algorithm; and using the updated feature vector of the face recognition base library for face recognition. In the aspect of face recognition, on the premise that a face recognition model is not changed, the face recognitionbase library feature vector is updated by utilizing the face image acquired by the equipment end, and the face feature vector is gradually iterated towards the direction of the feature center, so that style migration of a field environment is realized, the face recognition rate is improved, and the false recognition rate is reduced.

Description

technical field [0001] The present invention relates to the technical field of face recognition, in particular to a face recognition method, system and storage medium based on a dynamic threshold. Background technique [0002] At present, face recognition technology has been widely used in people's production and life. The general workflow is to enter personnel information in the background, including the face base database. In order to ensure the recognition effect and security, the photos in the base database need to undergo strict quality evaluation and liveness detection, and are different from the images acquired by the terminal camera. source, which may produce a large difference in data distribution, which will lead to a decline in the recognition rate. Moreover, the terminal equipment cannot be well controlled due to the environment. For example, the equipment may be deployed in a dark or backlit environment, and the quality evaluation of the face will not be contro...
