摘要
提出了一种单色表格的快速分析方法。其主要内容是:利用Radon变换检测表格的歪斜角度将其校正,用投影法找出表格线的位置,根据表格线的位置将待分割的栏目的图象提取出来。该方法具有较强的实用性,对表格设计和印刷的要求较低。
A rapid layout analysis method of single-color table is introduced in this paper.The skew angle of table image is detected and adjusted by Radon Transformation,then the positions of horizontal and vertical table-lines are found by projecting the table's image to the horizontal and vertical directions.We can segment the images of interested cells by the table-lines surrounding them.This method has good practicability with low demanding on the designing and printing of tables.
