The Kuwahara filter is a noise-reduction filter that preserves edges.

 

It can also be used to create various artistic effects.

This plugin is based off the Public Domain Kuwahara filter for ImageJ.

The Radius option controls the size of the filter sample area.

The Use RGB channels option controls whether the plugin uses the RGB channels or the "brightness" (HSV Value) when calculating the output color.
