ABSTRACT:
A method of reducing errors in optical character recognition (OCR) procedures includes digitizing an image of an object, the image containing alpha-numeric characters, and storing a bitmap of the digitized image as a scanned document file (SDF). An OCR step is performed to obtain at least one candidate character, and an indication of the at least one candidate character is stored in a textural results file (TRF). The font of the digitized image is determined and the font is stored in a regeneration library file (RLF). A regenerated image file is generated using the TRF and the RLF. At least a portion of the regenerated image file is compared with a corresponding portion of the bitmap of the digitized image stored in the SDF. The TRF is outputted if the results of the comparison indicate a match of at least the portion of the regenerated image file with the corresponding portion of the bitmap. If a match is not found, further processing is performed to resolve the mismatch.
