/**
* \class BSplineCenteredResampleImageFilterBase
* \brief Evaluates the Centered B-Spline interpolation of an image. Spline order may be from 0 to 5.
*
* This class defines N-Dimension CenteredB-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: Spline order must be between 0 and 5.
* Spline order must be set before setting the image.
* Uses mirror boundary conditions.
* Requires the same order of Spline for each dimension.
