ABSTRACT:
A method of separating finely textured and solid regions in a binary image from other regions such as those containing text and line graphics. The image is subjected to a first set of operations (10) that eliminates OFF pixels that are near ON pixels, which tends to thicken text and lines and solidify textured regions. The image is then subjected to a second set of operations (12) that eliminates ON pixels that are near OFF pixels. This thins out and eliminates the previously thickened text and lines, but leaves the previously solidified textured regions substantially intact.
