/** \class BSplineUpsampleImageFilter
* \brief Uses B-Spline interpolation to upsample an image by a factor of 2.
* This class is the public interface for spline upsampling as defined by the
* ResamplerType.
*
* Requires the use of a resampler type. If in doubt, the basic itkBSplineResampleImageFilterBase
* should work fine for most applications.
*
* This class defines N-Dimension B-Spline transformation.
* It is based on:
* [1] M. Unser,
* "Splines: A Perfect Fit for Signal and Image Processing,"
* IEEE Signal Processing Magazine, vol. 16, no. 6, pp. 22-38,
* November 1999.
* [2] M. Unser, A. Aldroubi and M. Eden,
* "B-Spline Signal Processing: Part I--Theory,"
* IEEE Transactions on Signal Processing, vol. 41, no. 2, pp. 821-832,
* February 1993.
* [3] M. Unser, A. Aldroubi and M. Eden,
* "B-Spline Signal Processing: Part II--Efficient Design and Applications,"
* IEEE Transactions on Signal Processing, vol. 41, no. 2, pp. 834-848,
* February 1993.
* And code obtained from bigwww.epfl.ch by Philippe Thevenaz
*
* Limitations: This class requires specification of a resampler type which may
* be one of:
* BSplineResampleImageFilterBase,
* BSplineL2ResampleImageFilterBase
* BSplineSplineCenteredResampleImageFilterBase,
* BSplineCenteredL2ResampleImageFilterBase
* The limitations of these resampler types will apply to this filter.
* Upsamples only by a factor of 2.
