* \class BinaryMorphologicalOpeningImageFilter
* \brief binary morphological closing of an image.
*
* This filter removes small (i.e., smaller than the structuring
* element) structures in the interior or at the
* boundaries of the image. The morphological opening of an image
* "f" is defined as:
* Opening(f) = Dilatation(Erosion(f)).
*
* The structuring element is assumed to be composed of binary
* values (zero or one). Only elements of the structuring element
* having values > 0 are candidates for affecting the center pixel.
