单向准连通的表格线检测算法

A System of Table Line Processing that Base on the One—way and Quasi Connection

针对表格框线存在倾斜、破裂、断裂及字符与表线粘连等情况,对表格柜线的检测方法进行了深入研究。采用了表格框线检测与处理相结合的方法获取表线。在表格框线检测中,提出基于单向准连通的检测方法,有效地克服了框线的倾斜、破裂及粘连等情况；在表格框线的处理中,采用对检测线的连接和筛选的方法,有效解决了表格框线断裂的问题。通过大量的实验,表明该方法能取得较好的检测效果。

Aiming at the case that the table line may be sloping, breaking, rupturing, or conglutinating with the words, we study the method of the line detecting carefully. By using the method that combine lines detecting and processing together, we can delete the table lines effectively. In the process of line detecting, we propose a method that base on One -way and quasi connection, which can overcome the problem that the table line is sloping, breaking, conglutination, effectively. The problem that the line is rupturing can be solved effectively by the method of lines connection and lines selection when process the lines. And through these methods, we can detect and delete the table line effectively in different cases. Lots of experiences have shown that the system can make very good detecting result.
