/** \class IntermodesThresholdCalculator
* \brief Computes the Intermodes's threshold for an image.
*
* J. M. S. Prewitt and M. L. Mendelsohn, "The analysis of cell images," in
* Annals of the New York Academy of Sciences, vol. 128, pp. 1035-1053, 1966.
* *
* Assumes a bimodal histogram. The histogram needs is smoothed (using a
* running average of size 3, iteratively) until there are only two local maxima.
* j and k
* Threshold t is (j+k)/2.
* Images with histograms having extremely unequal peaks or a broad and
* flat valley are unsuitable for this method.
*
* This class is templated over the input histogram type.
* \warning This calculator assumes that the input histogram has only one dimension.
