Thanks for suggessting these methods. I can see them defined as virtual in
ImageToImageMetric class. Is the implementation done so that I can obtain
expected bahaviour, if I call the methods from subclasses of
HistogramToImageMetric, e.g., NMI? In the ITK-1.8.1 this was not possible so I
filed a request of this feature into the ITK bugtracker.

Thanks.
