Mosaic of Subcultures

A quick search led me to a discussion on watercolor filters. The original poster put up something that I thought was pretty impressive, but replies argued otherwise.

One poster in particular pointed the group to a Kurahawa Filter as a potential replacement algorithm. Apparently it is a non-linear class of image filters if you read through his links. Interesting stuffs.

Here is a processing applet that approximates a Kurahawa 5x5 Filter.
