Detailed Description

A 2D Kuwahara filter implementation.

Performs the Kuwahara Filter, a noise-reduction filter that preserves edges. In the case of a 5x5 sampling window, the mean brightness and the variance of each of the four 3x3 regions, are calculated and the value of the center pixel is set to the mean value of the region that with the smallest variance.
