Finger vein recognition method, device, computer equipment and storage medium

Abstract

The present application relates to a finger vein recognition method, device, computer equipment and storage medium. The method includes: obtaining a finger vein image to be recognized, determining the translation information of the finger in the finger vein image to be recognized; extracting sensory information in the finger vein image to be recognized Area of ​​interest, feature extraction for the area of ​​interest, to obtain the finger vein feature map corresponding to the area of ​​interest; divide the finger vein feature map into multiple sub-areas, and set a corresponding weight value for each sub-area according to the pre-acquired empirical information ; If the finger deviates from the center line in the first direction in the finger vein image to be identified, the weight value of the preset sub-region in the first direction in the finger vein feature map is lower than the weight value in other sub-regions; The similarity between the finger vein image and multiple finger vein images in the preset database, and output the recognition result according to the similarity. The application can reduce the sensitivity to finger translation and improve the recognition rate.

Description

Technical field [0001] The present application relates to the field of identification technology, and more particularly to an intravenous identification method, a device, a computer device, and a storage medium. Background technique [0002] It is gradually widely used in the 21st century. The technique invented Japanese scientists in the 1990s. In the beginning of this century, it has been gradually applied to members, and South Korea has gradually applied to members. Bank ATM machine, access control Manage system, etc., you need to perform personal identity authentication. In recent years, intravenous identification technology is not only applied in traditional fields such as identification, attendance access control, but also has achieved great development in the field of medical border security and entertainment. The vein identification technology is to personal identify the intravenous pattern image obtained after infrared penetrating fingers, with the following advantages: ...

AI Technical Summary

Problems solved by technology

However, there are still some problems in the current finger vein recognition technology. For example, the finger vein recognition algorithm cannot overcome the influence of translation, resulting in a low recognition rate.
