I would like to fit splines instead of using regression because I want to be sure that the curve goes through each point I have given the PointSet.  I have experimented with BSplineScatteredDataPointSetToImageFilter, but I am beginning to think that this class was not designed for this purpose.  Maybe I am wrong.
