CHARACTER READER EXHIBITING ON-THE-FLY RECOGNITION TECHNIQUES

摘要

A character reader incorporates on-the-fly recognition techniques to recognize characters printed on documents. Recognition is dependent upon dividing the characters into a first plurality of horizontal zones as well as a pair of vertical zones to determine from which portion of a character certain selected features are derived. To eliminate ambiguities that may occur with such zoning techniques when poorly printed characters are read, the character reader also effectively divides each character into a second plurality of horizontal zones that overlay and are substantially broader than the first plurality of horizontal zones. Certain other selected features are read from the second plurality of horizontal zones.
