Detailed Description

template<class TImageType, class TCoordRep = double, class TCoefficientType = double>
class itk::BSplineInterpolateImageFunction< TImageType, TCoordRep, TCoefficientType >

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&ndash;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&ndash;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.

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.

The following methods take working space (evaluateIndex, weights, weightsDerivative) that is managed by the caller. If threadID is known, the working variables are looked up in the thread indexed arrays. If threadID is not known, working variables are made on the stack and passed to these methods. The stack allocation should be ok since these methods do not store the working variables, i.e. they are not expected to be available beyond the scope of the function call.

This was done to allow for two types of re-entrancy. The first is when a threaded filter, e.g. InterpolateImagePointsFilter calls EvaluateAtContinuousIndex from multiple threads without passing a threadID. So, EvaluateAtContinuousIndex must be thread safe. This is handled with the stack-based allocation of the working space.

The second form of re-entrancy involves methods that call EvaluateAtContinuousIndex from multiple threads, but pass a threadID. In this case, we can gain a little efficiency (hopefully) by looking up pre-allocated working space in arrays that are indexed by thread. The efficiency gain is likely dependent on the size of the working variables, which are in-turn dependent on the dimensionality of the image and the order of the spline.

The UseImageDirection flag determines whether image derivatives are computed with respect to the image grid or with respect to the physical space. When this flag is ON the derivatives are computed with respect to the coodinate system of physical space. The difference is whether we take into account the image Direction or not. The flag ON will take into account the image direction and will result in an extra matrix multiplication compared to the amount of computation performed when the flag is OFF. The default value of this flag is On.

void itk::BSplineInterpolateImageFunction< TImageType, TCoordRep, TCoefficientType >::SetSplineOrder ( unsigned int  SplineOrder)

Get/Sets the Spline Order, supports 0th - 5th order splines. The default is a 3rd order spline.

virtual void itk::BSplineInterpolateImageFunction< TImageType, TCoordRep, TCoefficientType >::SetUseImageDirection ( bool  _arg)
virtual

The UseImageDirection flag determines whether image derivatives are computed with respect to the image grid or with respect to the physical space. When this flag is ON the derivatives are computed with respect to the coodinate system of physical space. The difference is whether we take into account the image Direction or not. The flag ON will take into account the image direction and will result in an extra matrix multiplication compared to the amount of computation performed when the flag is OFF. The default value of this flag is On.
