Grows dark areas into light areas, or vice versa, by creating a box of a user-defined size around each pixel, sorting all
of the pixels in that box into order of intensity, determining the minimum or maximum pixel, and replacing the initial pixel
with that color. Useful for shrinking masks; use a larger box size to create artistic effects. The Min Max Filter is a sub-set
of the Rank Filter.
