/** \class MeanShiftImageFilter
*
*
* Mean shift is a data clustering algorithm often used in image processing and segmentation.
* For a given pixel, the mean shift will build a set of neighboring pixels within a given spatial
* radius (can be set using SetSpatialRadius()) and a color range (can be set using SetRangeRadius()).
* The spatial and color center of this set is then computed and the algorithm iterates with this new spatial
* and color center.
*
* Mean shift can be used for edge-preserving smoothing, or for clustering. The GetOutput() method will allow
* you to get the smoothed image, whereas the
* GetClusteredOutput() methods returns the clustered output. The GetLabeledClusteredOutput() returns
* a labeled clustered image, and the GetClusterBoundariesOutput()
* an image of the cluster boundaries.
*
* The MinimumRegionSize parameter allows you to prune small clustered regions.
*
* This filter uses the Edison mean shift algorithm implementation. Please note that data whose precision
* is more than float are casted to float before processing.
*
* The Scale parameter allows you to stretch the data dynamic
*
* For more information on mean shift techniques, one might consider reading the following article:
