Embodiment Construction

[0042] The present invention will be further described below in conjunction with accompanying drawing.

[0043] The present invention is a vein recognition method based on texture features, as attached figure 1 shown, including the following steps:

[0044] Step 1. Establishing an image library of the back of the hand: In this embodiment, an image library of the back of the hand of 102 people with left and right hands is established. Due to the difference in the distribution of the left and right hand veins of each individual, this library can be considered as the back of the hand images of 204 samples. This paper collects 10 pictures for each back of the hand, randomly selects 5 pictures in each category as the training set, and the other 5 pictures as the test set, so the total test set is 1020 pictures, where the picture format is bmp, and the gray scale is 256 levels, the size is 640*480 pixels, and the horizontal and vertical resolutions are both 96dpi.

Abstract

The invention discloses a vein recognition method based on texture features. The method includes the steps of firstly, creating a hand vein image library, images in each category being randomly divided into a training set and a testing set, and the number of images in the training set being the same as the number of images in the testing set; secondly, acquiring and pre-processing hand vein images; and thirdly, recognizing the vein images based on the texture features. The method of the invention is capable of targeted extraction based on the characteristics of vein directivity, has strong robustness and rotation invariance, and can achieve multi-resolution and multi-directional analysis. Meanwhile, the problem of feature dimension is solved and excellent effects are gained in an actual test.

Description

technical field [0001] The invention relates to a recognition method, in particular to a vein recognition method based on texture features. Background technique [0002] With the continuous development of communication equipment and Internet technology, information has spread in every corner of people's lives. Related to it, the importance of information security has been raised to an unprecedented height. Security inspection, justice, finance, mobile network, e-commerce, human-computer interaction and many other occasions require a complete authentication system to ensure information security, and the first prerequisite for ensuring security is to know who a person is. Therefore, the application of identification technology will become more and more important. [0003] Traditional identification methods include IC cards, keys, certificates, passwords, etc. Although these methods are practical, they also have obvious disadvantages. For example, certificates are easy to be ...
