/** \class HuangThresholdCalculator
* \brief Computes the Huang's threshold for an image.
*
* This calculator computes the Huang's fuzzy threshold which separates an image
* into foreground and background components. Uses Shannon's entropy
* function (one can also use Yager's entropy function)
* Huang L.-K. and Wang M.-J.J. (1995) "Image Thresholding by Minimizing
* the Measures of Fuzziness" Pattern Recognition, 28(1): 41-51
* Reimplemented (to handle 16-bit efficiently) by Johannes Schindelin Jan 31, 2011
*
* This class is templated over the input histogram type.
* \warning This calculator assumes that the input histogram has only one dimension.
