+Anisotropic Kuwahara node
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The **Anisotropic Kuwahara** node applies a smoothing filter (while preserving the edges of the image)
+to its input. This can be used to create stylized images with effects similar to painted brushstrokes.

+Inputs
+++++++
+
+The **Anisotropic Kuwahara** node has a single input.
+
+Outputs
++++++++
+
+The **Anisotropic Kuwahara** node outputs the result of the smoothing filter.

+Parameters
+++++++++++
+
+See also `Kuwahara node <https://docs.blender.org/manual/en/4.0/compositing/types/filter/kuwahara.html>`_
+on Blender docs for more details on *Size*, *Uniformity*, *Sharpness* and *Eccentricity*.
+
+The **Anisotropic Kuwahara** node accepts the following parameters:
+
+*  **Resolution** used to sample the input image.
+
+*  **Size** of the filter. Higher values can produce more stylized results.
+
+*  **Unifomity** of the image edges' directions.
+
+*  **Sharpness** of the edges of the image.
+
+*  **Eccentricity** affects the directionality of the filter.
