Embodiment Construction

[0058] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0059] A preferred embodiment of the present invention provides that according to one aspect of the present invention, an identification method based on finger vein features is provided. The method of this embodiment reads by extracting feature values ​​including: quality level, maximum curvature feature, and average curvature feature. The imported finger vein image is compared and matched with the image sample units stored in the database in advance. In the matching strategy, the weight and priority of the matching degree of the maximum curvature feature and the average curvature feature are set in combination with the quality level, which improves the finger vein. Accuracy and robustness of recognition. refer to figure 1 , the method of this embo...

Abstract

The invention discloses an identity recognition method and a system based on the finger vein characteristics. The method comprises the following steps of preprocessing a read-in finger vein image to obtain a corrected image sample unit; extracting characteristic values of the image sample unit, wherein the characteristic values comprise quality grade, maximum curvature characteristics and mean curvature characteristics, and the quality grade is divided into an excellent grade, an average grade and a poor grade; carrying out matching degree calculation on the characteristic values of the image sample unit and characteristic values of a registered image unit prestored in a database according to a matching strategy so as to carry out identity recognition, wherein the quality grade, the maximum curvature characteristics and the mean curvature characteristics corresponding to the registered image unit are prestored in the database, and the matching strategy is characterized in that the weight and the priority of the matching degree of the maximum curvature characteristics and the mean curvature characteristics are set according to the quality grades of the image sample unit and the registered image unit. According to the identity recognition method and the system based on the finger vein characteristics, the accuracy and the robustness of finger vein recognition are improved, and the finger vein recognition technology can be favorably popularized and applied.

Description

technical field [0001] The present invention relates to the field of biological feature identification, in particular to an identification method and system based on finger vein features. Background technique [0002] Biometric identification technology is the use of human physiological or behavioral characteristics to identify individuals. Because traditional identity authentication is extremely easy to forge and lose, it is becoming more and more difficult to meet the needs of the society. The most convenient and safe solution is biometric technology. Biometric technology is not only simple and fast, but also uses it for identity identification, which is safe, reliable and accurate. At the same time, it is easy to cooperate with the integration of computer and security, monitoring and management systems to realize automatic management. [0003] Each individual has unique biological characteristics that can be measured or automatically identified and verified, which can b...
