/** \class DilateObjectMorphologyImageFilter
* \brief dilation of an object in an image
*
* Dilate an image using binary morphology.
* Pixel values matching the object value are considered the
* "foreground" and all other pixels are "background". This is useful
* in processing mask images containing only one object.
*
* If a pixel's value is equal to the object
* value and the pixel is adjacent to a non-object valued pixel, then
* the kernel is centered on the object-value pixel and neighboring
* pixels covered by the kernel are assigned the object value.
* The structuring element is assumed to be composed of binary values
* (zero or one).
