IOCR: An intelligent optical character reader

Abstract

An intelligent optical character reader (IOCR) for reading printed English text with alphanumeric symbols is presented. There are seven major functional units in the system: a self trainer, a graphic editor, a database manager, a token extractor, a pattern matcher, a spelling checker and a guess by feature analyzer. The first three units provide facilities for reference pattern manipulation, while the last four units are for character recognition. The spelling check and the feature analysis are based on some intelligent statistical rules, and together they enhance the recognition rate
