/** \class BSplineResampleImageFunction
* \brief Resample image intensity from a BSpline coefficient image.
*
* This class resample the image intensity at a non-integer position
* from the input BSpline coefficient image.
*
* Spline order may be from 0 to 5.
*
* In ITK, BSpline coefficient can be generated using a
* BSplineDecompositionImageFilter. Using this image function in
* conjunction with ResampleImageFunction allows the reconstruction
* of the original image at different resolution and size.
