/** \class FastChamferDistanceImageFilter
* \brief This class compute the signed (positive and negative) chamfer distance in a narrow band
*
* \par OVERVIEW
* This filter computes a Signed Chamfer Distance Map of the input image
* specialy designed to work within the Level Set framework,
* in the Narrow Band Reinitialization (generally applied after
* IsoContourDistanceImageFilter ).
* It can however be used for other purposes.
*
* The input is assumed to contain voxels with values higher than
* the Maximal Computed Distance,
* or values between -1 and 1 for voxels close to the 0-isosurface
* from which we compute the distance.
*
* This filter is N-dimensional.
*
* \par REFERENCES
