摘要: 给出一种对签名特殊点的提取方法, 并以此特殊点作为签名的分割点, 获取每段中的重要特征进行分析. 在此基础上, 提出一种基于隐马尔可夫模型(HMM)的在线手写签名认证算法, 并利用第一届国际手写签名认证竞赛(SVC 2004)的测试数据库检验了算法的有效性.

关键词: 在线手写签名认证, 隐马尔可夫模型, 模式识别

Abstract: The extracting method of special points in signature is presented, which are used as signature segment points, and the extraction and selection of the features of each segment are analyzed on the basis of which the algorithm of online handwritten signature verification using hidden markov model (HMM) is presented. The algorithm was examined by signature data from SVC 2004 (The First International Signature Veri fication Competition).

Key words: online handwritten signature verification, hidden markov model (HMM), pattern recognition
