highlights but might introduce halos. Lower values reduce the size of halos but may lead to an artificial look. • Compress: This slider controls how strong the effect extends to mid-tones; high values radius for each, and subtracting them to yield the result. This algorithm is very widely used in artificial vision (maybe in biological vision as well!), and is pretty fast because there are very efficient them more easy to be treated in many domains (computer vision, pattern recognition and machine intelligence). GIMP’s aim is more humble: create a posterization effect. k-means clustering is one of the most

much as the Sharpen filter does, the resulting image will look much more natural than the somewhat artificial look that Sharpen will produce. Unsharp Mask can also be used to prepare images for Web and professional Values between 0.5 (50%) and 2.50 (250%) will produce a stronger sharpening. If you want to create artificial-looking images, high values over 4.5 (450%) will do. The given values assume that you have a Radius

In case you decide to design your own plug-in, another useful page can be found at http://www2.ai-lab.fh-furtwangen.de/~bless/the-gimp.html. This site, maintained by Marc Bless, has pointers to the
