Three OCR systems are employed for text conversion and the results generated from each of the three are merged using a edit distance algorithm to estimate a correct common text ancestor. To make the process computationally feasible for large strings such as pages of documentation with 3,000 characters,...http://www.google.es/patents/US5459739?utm_source=gb-gplus-sharePatente US5459739 - Merging three optical character recognition outputs for improved precision using a minimum edit distance function
