I'm looking for a "binary morphology open" that is only performed within 
the areas of the marker image. If I get the description of 
ReconstructionByDilation right then this is not what I need.
Is DilationByRecontruction (as mentioned in 
http://www.itk.org/Doxygen/html/classitk_1_1OpeningByReconstructionImageFilter.html) 
the same as ReconstructionByDilation?

Thanks a lot for Your help
