Latest Patents

John C Handley holds a patent for a method titled "Merging three optical character recognition outputs for improved accuracy." This patent involves the use of three OCR systems to convert text, with the results from each system being merged using an edit distance algorithm. This method estimates a correct common text ancestor, enhancing the accuracy of text recognition. To ensure computational feasibility for large strings, such as pages of documentation with 3,000 characters, the process is executed in two stages. The first stage considers each page as a string of lines, using edit distance to find optimal line alignments. In cases where choices must be made among three non-null lines, the procedure is invoked on those lines, utilizing character-level edit distance for optimal alignment. The method also incorporates heuristic techniques to reduce the number of computations required, determining an upper bound on the edit distance.
