摘要:

本文提出了一种与作者相关的签名验证方法。两种不同类型的纹理特征,即小波和局部量化模式(LQP)的功能,提取两种基于变换和统计的信息签名图像。对于每个作家两个单独的一类支持向量机(SVM)对应的LQP和小波特征的每一个集合进行训练,以获得两个不同的真实性得分为一个给定的签名。最后,使用一种分数级分类器融合方法,将两个单类支持向量机的分数进行融合,得到验证分数。在所提出的方法中,只有真正的签名被用来训练的一类支持向量机。所提出的签名验证方法已经使用四个不同的公开可用的数据集进行了测试,结果表明所提出的方法的通用性。所提出的系统优于文献中的其他现有系统。

英文摘要:

In this paper, a writer-dependent signature verification method is proposed. Two different types of texture features, namely Wavelet and Local Quantized Patterns (LQP) features, are employed to extract two kinds of transform and statistical based information from signature images. For each writer two separate one-class support vector machines (SVMs) corresponding to each set of LQP and Wavelet features are trained to obtain two different authenticity scores for a given signature. Finally, a score level classifier fusion method is used to integrate the scores obtained from the two one-class SVMs to achieve the verification score. In the proposed method only genuine signatures are used to train the one-class SVMs. The proposed signature verification method has been tested using four different publicly available datasets and the results demonstrate the generality of the proposed method. The proposed system outperforms other existing systems in the literature.
