/** \class GrayscaleGeodesicDilateImageFilter
* \brief geodesic gray scale dilation of an image
*
* Geodesic dilation operates on a "marker" image and a "mask"
* image. The marker image is dilated using an elementary structuring
* element (neighborhood of radius one using only the face connected
* neighbors). The resulting image is then compared with the mask
* image. The output image is the pixelwise minimum of the dilated
* marker image and the mask image.
*
* Geodesic dilation is run either one iteration or until
* convergence. In the convergence case, the filter is equivalent to
* "reconstruction by dilation". This filter is implemented to handle
* both scenarios. The one iteration case is multi-threaded. The
* convergence case is delegated to another instance of the same
* filter (but configured to run a single iteration).
*
* The marker image must be less than or equal to the mask image
* (on a pixel by pixel basis).
*
* Geodesic morphology is described in Chapter 6 of Pierre Soille's
* book "Morphological Image Analysis: Principles and Applications",
* Second Edition, Springer, 2003.
*
* A noniterative version of this algorithm can be found in the
* ReconstructionByDilationImageFilter. This noniterative solution is
* much faster than the implementation provided here. All ITK filters
* that previously used GrayscaleGeodesicDiliateImageFilter as part of
* their implementation have been converted to use the
* ReconstructionByDilationImageFilter. The
* GrayscaleGeodesicDilateImageFilter is maintained for backward
* compatibility.
