Abstract
A system is provided for repairing a binary image image containing discontinuous segments of a character. The binary image comprises a two-dimensional array of pixels, and the system comprises a device for storing the binary image, and a processor for performing various steps, including (1) creating a morphological filter, (2) mapping the morphological filter onto a selected region of the binary image, wherein each element of the morphological filter corresponds to a pixel of the binary image, (3) for each of the elements of the morphological filter of the first filter type, determining whether the corresponding pixel of the binary image is set and any of the pixels of the binary image corresponding to the elements of the morphological filter of the second filter type are set, and (4) setting the pixel of the binary image corresponding to the center element of the morphological filter, responsive to the previous step.
