ABSTRACT:
The invention provides a method of processing an image containing written information include the steps of (a) scanning a surface of an object to obtain an image of the surface represented by first image data, (b) creating second image data from the first image data, the second image data having a lower data density than the first image data, (c) analyzing the second image data with first image analysis logic to decode the written information, and (d) if the written information cannot be decoded to a desired extent from the second image data, analyzing the first image data with second image analysis logic different from the first image analysis logic to decode the written information. Steps (a) and (b) preferably use a single scanning device to create the high data density image (e.g., color or grayscale) from which the lower data density image (e.g., binary or black and white) can then be created. The resulting two-stage image analysis provides a significant improvement in OCR results. Further, when a pre-printed bar code is present but does not result in a destination bar code, using the methods of step7,determining the destination address zip code using OCR techniques, printing the resultant ZIP Code and sorting the mail based on the new OCR derived data.
