KuwaharaFilter[image, r]
computes for each pixel p in image the variance of the values in the four 
×
squares that have p as a corner, and replaces p with the mean of the values of the square with least variance.
Details
- KuwaharaFilter is a non-linear local filter typically used for edge-preserving smoothing.
- KuwaharaFilter works with binary, grayscale, and color images. For multi-channel images, KuwaharaFilter computes the sum of the variances in each channel.
- At the edges of an image, KuwaharaFilter uses smaller neighborhoods.
- KuwaharaFilter works with 3D as well as 2D images, and also with data arrays of any rank.
- KuwaharaFilter[image, {rrow, rcol}] uses range
in height, and 
in width. - KuwaharaFilter[image, {rslice, rrow, rcol}] uses range
in height, 
in depth, and 
in width.
