9 * \brief Resample image intensity from a VectorBSpline coefficient image using a LUT.
11 * This class resample the image intensity at a non-integer position
12 * from the input VectorBSpline coefficient image using a LUT.
14 * Spline order may be from 0 to 5.
16 * In ITK, VectorBSpline coefficient can be generated using a
17 * VectorBSplineDecompositionImageFilter. Using this image function in
18 * conjunction with ResampleImageFunction allows the reconstruction
19 * of the original image at different resolution and size.
