| 摘 要： | 提出一种新的基于竞争聚类的离线签名验证算法。在注册阶段，通过样本特征的相关系数检查样本的一致性；在验证阶段，利用样本与待验签名的竞争聚类结果判断待验签名的真伪。实验结果表明，该算法不需用阈值来进行控制，能有效地降低误纳率。

| Abstract: | In this paper,a new off-line signature verification algorithm based on competitive cluster is presented.In the register phase,the correlation coefficient is calculated for checking the consistency of the data sets.In the verification phase,the questionable signature is verified by the competitive cluster which the questionable signature and the samples are involved in.No need for threshold controlling,the experiment shows minimization of false acceptance rate. |
