基于生成码的手指静脉识别

Finger Vein Recognition by Generating Code

Zhongxia Zhang, Mingwen Wang

摘要:

手指静脉识别以其高度的识别能力、安全性和非侵入性等优点,成为当前最受关注和最有发展前途的生物特征识别技术之一。传统方法的主要思想是直接从手指静脉图像或模式中提取特征,然后比较特征以找到最佳匹配。然而,从图像中提取的特征包含大量的冗余数据,而从模式中提取的特征受图像分割方法的影响很大。针对这些问题,本文提出了一种新的基于代码生成的手指静脉识别方法.该方法不需要图像分割算法,计算简单,数据量小。首先对手指静脉图像进行分块计算均值;然后利用生成的特征矩阵进行中心对称编码。所获得的码字被连接作为图像的特征码字。静脉代码之间的相似性度量的最小汉明距离的码字长度的比值。在两个公共手指静脉数据库上的实验验证了该方法的有效性。结果表明,我们的方法优于国家的最先进的方法,并在执行匹配任务的竞争潜力。

英文摘要:

Finger vein recognition has drawn increasing attention as one of the most popular and promising biometrics due to its high distinguishes ability, security and non-invasive procedure. The main idea of traditional schemes is to directly extract features from finger vein images or patterns and then compare features to find the best match. However, the features extracted from images contain much redundant data, while the features extracted from patterns are greatly influenced by image segmentation methods. To tack these problems, this paper proposes a new finger vein recognition by generating code. The proposed method does not require an image segmentation algorithm, is simple to calculate and has a small amount of data. Firstly, the finger vein images were divided into blocks to calculate the mean value. Then the centrosymmetric coding is performed by using the generated eigenmatrix. The obtained codewords are concatenated as the feature codewords of the image. The similarity between vein codes is measured by the ratio of minimum Hamming distance to codeword length. Extensive experiments on two public finger vein databases verify the effectiveness of the proposed method. The results indicate that our method outperforms the state-of-theart methods and has competitive potential in performing the matching task.
