<p><it>Abstract</it>—Many current optical character recognition (OCR) systems attempt to decompose printed pages into a set of zones, each containing a single column of text, before converting the characters into coded form. We present a methodology for automatically assessing the accuracy of such decompositions, and demonstrate its use in evaluating six OCR systems.</p>
