/**
 * \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
