Table Layout Analysis Based on Optimal Coordinates System
Chen Ji-rong · Jisuanji fangzhen · 2007
Table documents are frequently used in daily life. Automatically handling this kind of documents by computer can not only save time but also offer high accuracy. The layout structure extraction of the table documents is the kernel of the automatic processing of table information. Because the images of table documents always consist of printed and handwritten characters, images, defiles, noises and tilts, it is difficult to extract the layout structure correctly. After summarizing the existing methods of layout structure extraction, this paper presents a new method based on optimal coordinates system to get the layout structure. The new method outperforms the traditional ones in noise-resisting and layout definition.
