Hi Waltraut,

This filter will work in ND thanks to the internal
use of the FloodFillIterator.

You will find a 2D example in

     Insight/Examples/Segmentation

and a 3D application with FLTK GUI in

     Insight/Applications/RegionGrowingSegmentation

This filter is miss-leading since it is based in an
apparently simple concept. However, so far it has
proved to be the most cost-effective segmentation
algorithm in the toolkit and has been used succesfully
over a variety of different image modalities.

Note that you may improve the initial estimation of
statistics around the seed by using the method

       SetInitialNeighborhoodRadius()

Just make sure, as Jim said, that the entire initial
neighborhood is well inside the object and is has an
intensity distribution typical of the object.

The filter is discussed in the SoftwareGuide in the
section:

   Segmentation/
       Region Growing/
          Confidence Connected
