HIERARCHICAL REPRESENTATION OF OPTICALLY SCANNED DOCUMENTS

Abstract

The objective of the research to be pursued is to develop a schema for representing raster-digitized (scanned) documents, The representation is to retain not only the spatial structure of a printed document, but should also facilitate automatic labeling of various components, such as text, figures, subtitles, and figure captions, and allow the extraction of important relationships (such as reading order) among them. Intended applications include (1) data compression for document transmission and archival, and (2) document entry, with out rekeying, into editing, formatting, and information retrieval systems.
