ABSTRACT:
Page segmentation which scans a document to detect black and white run lengths along scanlines, finds grey intervals each defined as being between two long white or mostly white intervals of a scanline or between an end of the scanline and a long (mostly) white interval, links adjacent grey intervals into grey areas, and identifies such grey areas as text or halftone, prior to a larger process such as character recognition.
