description: Erode or dilate input stream using a normalized power-weighted filter.
This gives a smoother result than the Erode or Dilate node.
See "Robust local max-min filters by normalized power-weighted filtering" by L.J. van Vliet, http://dx.doi.org/10.1109/ICPR.2004.1334273
Uses the 'vanvliet' and 'deriche' functions from the CImg library.

title: Size
description:
Size (diameter) of the filter kernel, in pixel units (>=0). The standard deviation of the corresponding Gaussian is size/2.4. No filter is applied if size < 1.2. Negative values correspond to dilation, positive valies to erosion. Both values should have the same sign.

title: Exponent
description:
Exponent of the normalized power-weighted filter. Lower values give a smoother result. Default is 5.

minimum: 1
maximum: 10
default: 5
title: Border Conditions
description:
Specifies how pixel values are computed out of the image domain. This mostly affects values at the boundary of the image. If the image represents intensities, Nearest (Neumann) conditions should be used. If the image represents gradients or derivatives, Black (Dirichlet) boundary conditions should be used.

title: Filter
description:
Bluring filter. The quasi-Gaussian filter should be appropriate in most cases. The Gaussian filter is more isotropic (its impulse response has rotational symmetry), but slower.

title: (Un)premult
description:
Divide the image by the alpha channel before processing, and re-multiply it afterwards. Use if the input images are premultiplied.
