表格文件图象逻辑结构提取方法

近几年来，国内外已提出了许多关于表格文件图象分析的方法，但其中关于表格逻辑结构提取物方法却很少，为此，提出了一种关于表格文件逻辑结构撮的方法，此方法主要分为整表的全局划分、局部的逻辑结构分析和整表的再次全局划分３个步骤，该方法强调对文件全局和局部布局结构的综合分析，与以往的仅仅从局部上对表格逻辑结构进行了确定的方法相比，它具有较高的识别正确率，并可以识别结构更为复杂的表格文件。

Logical Structure Extraction of Form Document Image

Many methods on form document image analysis have been proposed, but few have treated the extraction of logical structure. A new method for the logical structure extraction of form document is proposed in this paper. The algorithm of it consists of three phases: global division of the whole document, local logical structure analysis and global re division of the whole document. This method emphasizes the synthetic analysis of the global and local layout structure of a form document. Compared with other local layout structure analysis methods, it has higher accuracy and can treat with more complex form documents.
