/** \class ValuedRegionalMinimaImageFilter
* \brief Transforms the image so that any pixel that is not a
* regional minima is set to the maximum value for the pixel
* type. Pixels that are regional minima retain their value.
*
* Regional minima are flat zones surrounded by pixels of higher
* value. A completely flat image will be marked as a regional minima
* by this filter.
