】手掌可以用于疾病诊断．掌纹线所组成的不同形状(结构)在疾病诊断中占有极其重要的地位，

准确识别这些掌纹线的不同结构，对于提高自动掌纹诊病系统的正确率有非常重要的意义．要进行有效的掌纹线

结构识别，首先必须将掌纹线结构准确地表示出来．本文提：B一种基于无向图的掌纹线结构表示方法，实验结果

表明该方法可以较为完整地表示出掌纹线的结构，这为进一步进行自动掌纹诊病研究打下了必要的基础．-】 Palm can be used for disease diagnosis. Palmprint line up of different shapes (structures) in the diagnosis of diseases occupy an important position, accurate identification of the different structures of these palm lines, automatic Palmprint Diagnosis System for improving the accuracy of very important significance. To carry out effective palmprint line structure identification, the first palm line structure must be accurately represent them. This article mentioned: B based on palm lines undirected graph structure representation, experimental results show that the method can be expressed more completely the structure of palm lines, which automatically palm medical consultation for further research to lay the necessary foundation .
