ABSTRACT:
A page analysis system which analyzes image data of a document page includes analysis of image data of one of a plurality of portions of the page, identification of a block of image data which has an association to another separate block of image data, and determination of whether or not picture information in the image data is half-tone line-drawing, joint-line, or unknown.
