Logical Structure Extraction of Form Document Image
表格文件图象逻辑结构提取方法

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.
