在简要分析表格结构的基础上，提出了一种利用变尺度连通 特征提取表格字符的方法.为此，给出了连通区域搜索算法，定义了用于区分表格与图形的 行程位置转化函数.并介绍了实验的情况.
On the base of the analysis of form's structure, a method with scale-changed connected area feature is put forward used for table extraction. So a researching algorithm of connected area is given, a function o f routing change position is defined for the distinguish of table and graph. And the results of experiment is introduced.
