+% KuwaharaImage() is an edge perserving blur.
+%
+% The format of the KuwaharaImage method is:
+%
+% Image *KuwaharaImage(const Image *image,const double radius,
+% const double sigma,ExceptionInfo *exception)
+%
+% A description of each parameter follows:
+%
+% o image: the image.
+%
+% o radius: the radius of the Gaussian, in pixels, not counting the center
+% pixel.
+%
+% o sigma: the standard deviation of the Gaussian, in pixels.
+%
+% o exception: return any errors or warnings in this structure.
