Abstract

The invention discloses a feature progressive finger vein image accurate matching method based on a ULBP (Uniform Local Binary Pattern) and SURF. The method comprises the following steps: S1, preprocessing a finger vein image; S2, carrying out image enhancement on the preprocessed image; S3, matching the extracted features with feature information in a database, and outputting a matching result. A coarse-to-fine finger vein recognition algorithm is realized; the problems that a single ULBP algorithm is small in gray scale range and low in recognition precision, and time consumption is too long when matching is conducted through SURF feature points are solved.

Description

technical field [0001] The invention relates to the field of recognition algorithms, in particular to an accurate matching method of finger vein images based on ULBP and SURF feature progression. Background technique [0002] With the gradual acceleration of information construction, this society is becoming more and more intelligent, and the ways people use for identification tend to be diversified. Identification technology is more and more used in people's daily life, but identification technology with low security level may cause greater property or item loss. Therefore, people have higher requirements for the security performance of identification, and they all hope to avoid the misfortune caused by wrong identification. At present, traditional identification methods mainly rely on distinguishable information such as keys, ID cards, passwords, tokens, etc., but these information need to be carried with you, so there are disadvantages such as easy to leak, easy to lose,...
