The filter is used to reduce noise while preserving edges. It can be used to create a cartoon effect from photorealistic images. It offers two variations: 1) Classic aka isotropic kuwahara filter: simple and faster computation. Algorithm splits an area around a single pixel in four parts and computes the mean of the region with the lowest standard deviation. 2) Anisotropic Kuwahara filter: improves the classical approach by considering the direction of structures of regions This patch implements both approaches above as multi-threaded operations for the full-frame and tiled compositor.
