Description
Apply a median filter to an Image. This replaces the red,
green, and blue components of each pixel with the median values of
those components in a circle of radius r
centered on the pixel. The result is an image with less noise
than the original. The given radius is in
units of the pixel size. If radius=0, then an
optimal radius will be chosen automatically.
This routine comes from the ImageMagick library.
