ABSTRACT:
An optical character recognition system cuts between touching characters. A first cut is made between touching characters based on white spaces, and the cut characters are subjected to character recognition processing. All characters not recognized are then cut again. A pair of adjacent vertical bars is detected in a vertical histogram of character image data of unrecognized characters, the vertical bars having a vertical component in the histogram that exceeds a predetermined vertical threshold. Horizontal crossings are detected in each of three discrete horizontal bands between the vertical bars. The vertical bars are classified according to the detected horizontal crossings, and, based on the classification, a decision is made whether or not to cut between the vertical bars, and where to cut between the vertical bars.
