/** \class ClosingByReconstructionImageFilter
* \brief Closing by reconstruction of an image
*
* This filter is similar to the morphological closing, but contrary
* to the mophological closing, the closing by reconstruction
* preserves the shape of the components. The closing by
* reconstruction of an image "f" is defined as:
*
* ClosingByReconstruction(f) = ErosionByReconstruction(f, Dilation(f)).
*
* Closing by reconstruction not only preserves structures preserved by
* the dilation, but also levels raises the contrast of the darkest
* regions. If PreserveIntensities is on, a subsequent reconstruction
* by dilation using a marker image that is the original image for all
* unaffected pixels.
*
* Closing by reconstruction is described in Chapter 6.3.9 of Pierre
* Soille's book "Morphological Image Analysis: Principles and
* Applications", Second Edition, Springer, 2003.
