Abstract
A document to be processed is scanned into a machine readable image. The image is segmented into a plurality of fields. Predetermined characteristics are measured for each field and the set of characteristics is correlated with a predetermined set of characteristics derived from a reference image. The fields with the highest degree of correlation to the characteristics from the reference document are selected for further processing, e.g., optical character recognition.
