Abstract

The invention provides a finger vein recognition method and system fusing basic features and deformation features. The recognition method mainly comprises the steps of image preprocessing, basic feature extraction, objective function construction and optimization and matching, deformation information extraction and basic feature and deformation feature fusion. According to the method, in the recognition process, deformation information is utilized, basic characteristics, matching scores and other information needed when the deformation characteristics are obtained are considered, and a fingervein recognition framework integrating the basic characteristics and the deformation characteristics is constructed. According to the method, the problem that when a single feature is used, the feature representation ability is insufficient is solved, the accuracy and robustness of finger vein recognition are improved, and the recognition efficiency is ensured.

Description

Technical field

[0001] The present disclosure relates to the technical field related to biometric recognition, and specifically, to a finger vein recognition method and system that integrates basic features and deformation features. Background technique

[0002] The statements in this section merely provide background information related to the present disclosure, and do not necessarily constitute prior art.

[0003] Among the many biometric recognition technologies, finger vein recognition has received extensive attention from researchers because of its convenience and safety. It uses the vein distribution image in the finger for identity recognition, and compares the obtained finger vein feature information with the pre-registered finger vein feature to confirm the identity of the registrant. Finger veins refer to the veins and blood vessels distributed inside the fingers, which can be imaged by the absorption of near-infrared light by hemoglobin. The finger is a three-dimensio...
