/** \class RecursiveMultiResolutionPyramidImageFilter
* \brief Creates a multi-resolution pyramid using a recursive implementation.
*
* RecursiveMultiResolutionPyramidImageFilter creates an image pryamid
* according to a user defined multi-resolution schedule.
*
* If a schedule is downward divisible, a fast recursive implementation is
* used to generate the output images. If the schedule is not downward
* divisible the superclass (MultiResolutionPyramidImageFilter)
* implementation is used instead. A schedule is downward divisible if at
* every level, the shrink factors are divisible by the shrink factors at the
* next level for the same dimension.
*
* See documentation of MultiResolutionPyramidImageFilter
* for information on how to specify a multi-resolution schedule.
*
* This class is templated over the input image type and the output image type.
*
* This filter uses multithreaded filters to perform the smoothing and
* downsampling.
*
* This filter supports streaming.
*
* \sa MultiResolutionPyramidImageFilter
