This instantiation won't even work in C++.  Look at the documentation 
for ImageToHistogramGenerator:

/** \class ImageToHistogramGenerator
  *  \brief This class generates an histogram from an image.
  *
  *  The concept of Histogram in ITK is quite generic. It has been 
designed to
  *  manage multiple components data. This class facilitates the 
computation of
  *  an histogram from an image. Internally it creates a List that is 
feed into
  *  the ListSampleToHistogramGenerator.
  *
  */

It is meant only for multiple component data, not scalar images like 
image::US2.
