Detailed Description

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

Uses the "l2" spline pyramid implementation of B-Spline Filters to up/down sample an image by a factor of 2.

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 for the l2 pyramid must be between 0 and 3. This code cannot be multi-threaded since the entire image must be traversed in the proper order. This code cannot be streamed and requires the all of the input image. Only up/down samples by a factor of 2. This is a base class and is not meant to be instantiated on its own. It requires one of the itkBSplineDownsampleImageFilter or itkBSplineUpsampleImageFilter classes.
