-% StatisticImage() makes each pixel the min / max / median / mode / etc. of
-% the neighborhood of the specified width and height.

-% The format of the StatisticImage method is:
-%
-% Image *StatisticImage(const Image *image,const StatisticType type,
-% const size_t width,const size_t height,ExceptionInfo *exception)
-%
-% A description of each parameter follows:
-%
-% o image: the image.
-%
-% o type: the statistic type (median, mode, etc.).
-%
-% o width: the width of the pixel neighborhood.
-%
-% o height: the height of the pixel neighborhood.
