Abstract

The invention relates to the technical field of biological feature recognition, in particular to a finger three-mode fusion recognition method, system and device and a storage medium, and the method comprises the steps of carrying out the normalization processing of a finger three-mode weighted graph through a parallel network, and obtaining the features of a finger three-mode graph; and fusing the finger three-mode graph features through a competition fusion method and a feature vector centrality fusion method to obtain fused features. According to the invention, the finger three-modal features are constructed into the graph features with consistent feature space based on the superpixel segmentation method, and meanwhile, the effective fusion of the finger three-modal graph features is realized by utilizing the node feature information and the structure information of the graph, so that the finger three-modal recognition precision is remarkably improved; in addition, the problem that effective fusion of finger three-mode features is affected due to inconsistent sizes of three-mode images is effectively solved through a parallel network.

Description

technical field [0001] The present invention relates to the technical field of biological feature recognition, in particular to a method, system, device and storage medium for three-modal fusion recognition of fingers based on a graph convolutional neural network. Background technique [0002] With the rapid development of the information age, intelligent identification systems can be seen everywhere in people's life and work, such as mobile phones, security inspection machines, access control machines and various online payment software, which promotes the development of identification technology; traditional The current identification technology can no longer meet people's needs for high-performance identification. Therefore, the identification technology based on biometrics has become the focus of researchers. [0003] At present, biometric recognition technology has become an important branch in the field of pattern recognition, and it is also one of the key development ...
