ABSTRACT:
A system, method and program product for cleaning a black white image. A system is disclosed that includes a filtering system that applies a filter to the black white image, wherein the filter examines a set of neighboring pixels of each black pixel and determines if a black pixel being examined should be converted to a white pixel; and a recursive application system that causes the filtering system to repeatedly re-filter the black white image until a determination is made that the black white image is sufficiently cleaned.
