  • Method of processing of a single raster element of a skeletonized binary image through the use of tiles
    Patent number: 6754396
    Abstract: A process for producing a skeleton from a raster image by overlaying a plurality of tiles on the raster image, wherein each of the tiles identifies a sub-region of the raster image comprised of a plurality of pixels. The sub-regions are selectively skeletonized and then cached for subsequent access. Some or all of the cache is invalidated when one or more of the sub-regions are modified. Only those sub-regions that have been modified are re-skeletonized, on an “as needed” basis.
