/** \class ReconstructionByErosionImageFilter
* \brief grayscale reconstruction by erosion of an image
*
* Reconstruction by erosion operates on a "marker" image and a "mask"
* image, and is defined as the erosion of the marker image with
* respect to the mask image iterated until stability.
*
* 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 6.2 of Pierre Soille's
* book "Morphological Image Analysis: Principles and Applications",
* Second Edition, Springer, 2003.
*
* Algorithm implemented in this filter is based on algorithm described
* by Kevin Robinson and Paul F. Whelan in "Efficient Morphological
* Reconstruction: A Downhill Filter", Pattern Recognition Letters, Volume
* 25, Issue 15, November 2004, Pages 1759-1767.
*
* The algorithm, a description of the transform and some applications
* can be found in "Morphological Grayscale Reconstruction in Image Analysis:
* Applications and Efficient Algorithms", Luc Vincent, IEEE Transactions on
* image processing, Vol. 2, April 1993.
*
* \author Richard Beare. Department of Medicine, Monash University,
* Melbourne, Australia.
