Disclosed is a segmentation algorithm of an optical character recognition system for segmenting or breaking up images of roughly printed characters into separate, distinct images of each character. The roughly printed character means a character printed by separate or discontinuous black dots. Run-end data representing the discontinuous black dots in the character is modified to recognize the roughly printed character as a character drawn by continuous black dots. The figure shows examples of the roughly printed characters, i.e., numerals 7 and 8, which are printed by discontinuous black dots. The roughly printed numerals 7 and 8 are segmented from each other in the following manner. The images of the numerals 7 and 8 are stored in an image memory, (not shown). The images are scanned from top to bottom.
