ABSTRACT:
Low cost, high-speed, optical character isolation and page reconstruction system, method and apparatus are presented which overcome problems caused by copied pages, noise, underlines, skewed and bowed text, forms features, logos and signatures. As characters or noise are isolated and recognized, their corresponding bit patterns in memory are deleted. Recognized characters are isolated within entire words at a time to form page image records which are then linked to form lines of words. The text on the original page is then reconstructed from lines of words to yield output signals suitable for input to a host word processor.
