Detailed Description

template<class TImageType, class TCoordRep = float>
class itk::BSplineInterpolateImageFunction< TImageType, TCoordRep >

Evaluates the B-Spline interpolation of an image. Spline order may be from 0 to 5.

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

The B spline coefficients are calculated through the BSplineDecompositionImageFilter

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. Spline is determined in all dimensions, cannot selectively pick dimension for calculating spline.

Member Function Documentation

template<class TImageType, class TCoordRep = float> virtual OutputType itk::BSplineInterpolateImageFunction< TImageType, TCoordRep >::EvaluateAtContinuousIndex (  const ContinuousIndexType &    index )  const [virtual]

Evaluate the function at a ContinuousIndex position. Returns the B-Spline interpolated image intensity at a specified point position. No bounds checking is done. The point is assume to lie within the image buffer. ImageFunction::IsInsideBuffer() can be used to check bounds before calling the method. Implements itk::InterpolateImageFunction< TImageType, TCoordRep >.
