Abstract
Two complementary methods are proposed for characterizing the spatial structure of digitized technical documents and labelling various logical components without using optical character recognition. The top-down method segments and labels the page image simultaneously using publication-specific information in the form of a page-grammar. The bottom-up method naively segments the document into rectangles that contain individual connected components, combines blocks using knowledge about generic layout objects, and identifies logical objects using publication-specific knowledge. Both methods are based on the X-Y tree representation of a page image. The procedures are demonstrated on scanned and synthesized bit-maps of the title pages of technical articles.This publication has 0 references indexed in Scilit:
