Method and means for enhancing optical character recognition of printed documents

摘要: A document marker, including first values dependent upon the layout and contents of assigned by generating or preprocessing software, is provided in machine-readable symbology on face a printed version document. The marker may include encoded information sequences original text, text-dependent decimation sequences, error correction codes check-sums. Upon optical character recognition scanning, other digitizing reproduction, also scanned. scanning computer, having corresponding assigns second reproduced comparison line errors can be detected some corrected, thereby re-aligned candidate sequences. Optional provide further correcting capabilities, as applied to sequences; and, an optional check-sum utilized verify accuracy are correct.
