#include <itkMultiOrderBSplineDecompositionImageFilter.h>

Detailed Description

template<class TInputImage, class TOutputImage>
class itk::MultiOrderBSplineDecompositionImageFilter< TInputImage, TOutputImage >

Calculates the B-Spline coefficients of an image. Spline order may be per dimension from 0 to 5 per.

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: Spline order must be between 0 and 5. Spline order must be set before setting the image. Uses mirror boundary conditions. Can only process LargestPossibleRegion
