Abstract

A hierarchical data structure for the representation of document images in vector form is suggested, which allows to store in compact form all needed information about connected components, segments and feature points. The process steps for obtaining this data structure are described. A fast one-pass algorithm for the transformation of a large-size thinned image into the vector form is suggested. The defects which can exist in the vector representation are extracted and an algorithm for their reduction is shortly described. Experimental results are also shown.
