The unsharp mask is a sharpening filter that works by comparing using the difference of the image and a blurred version of the image. It is commonly used on photographic images, and is provides a much more pleasing result than the standard sharpen filter.
Winston Chang; 1999

INT32	run_mode	Interactive, non-interactive
