Abstract

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. GLG method emphasizes the global layout structure analysis and has higher accuracy. It is robust for treating with the accidental direct adjacent relationship between two irrelated cells. In addition, a logical structure tree is proposed to represent the logical structure of a form document.
