/**
* \class LocalHistogramImageFunction
* \brief Calculate a local histogram over a specified circular neighborhood
*
* This image function computes the local histogram of the pixels lying
* in a circular neighborhood around the given position.
*
* Pixel count can be optionnaly weighted by a gaussian kernel with
* \f$ \sigma = 0.5 radius \f$ so that pixel far from the center position
* account less in the histogram than pixel near the center position.
* This option can be deactivated using the GaussianSmoothing flag.
*
* Histogram mininimum value, maximum value and number of bins can be
* set using the Setters/Getters.
*
* This class is templated over the input image type and the
* coordinate representation type (e.g. float or double).
*
* \ingroup ImageFunctions
*
* \ingroup OTBStatistics
