Detailed Description

convert image to b-spline knots

vtkImageBSplineCoefficients prepares an image for b-spline interpolation by converting the image values into b-spline knot coefficients. It is a necessary pre-filtering step before applying b-spline interpolation with vtkImageReslice.

This class is based on code provided by Philippe Thevenaz of EPFL, Lausanne, Switzerland. Please acknowledge his contribution by citing the following paper: [1] P. Thevenaz, T. Blu, M. Unser, "Interpolation Revisited," IEEE Transactions on Medical Imaging 19(7):739-758, 2000.

The clamped boundary condition (which is the default) is taken from code presented in the following paper: [2] D. Ruijters, P. Thevenaz, "GPU Prefilter for Accurate Cubic B-spline Interpolation," The Computer Journal, doi: 10.1093/comjnl/bxq086, 2010.

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkThreadedImageAlgorithm.

virtual void vtkImageBSplineCoefficients::SetSplineDegree ( int )

virtual

Set the degree of the spline polynomial. The default value is 3, and the maximum is 9.

virtual int vtkImageBSplineCoefficients::GetSplineDegree ( )

virtual

Set the degree of the spline polynomial. The default value is 3, and the maximum is 9.

virtual void vtkImageBSplineCoefficients::SetBorderMode ( int )

virtual

Set the border mode. The filter that is used to create the coefficients must repeat the image somehow to make a theoritically infinite input. The default is to clamp values that are off the edge of the image, to the value at the closest point on the edge. The other ways of virtually extending the image are to produce mirrored copies, which results in optimal smoothness at the boundary, or to repeat the image, which results in a cyclic or periodic spline.

void vtkImageBSplineCoefficients::SetBorderModeToClamp ( )

inline

Set the border mode. The filter that is used to create the coefficients must repeat the image somehow to make a theoritically infinite input. The default is to clamp values that are off the edge of the image, to the value at the closest point on the edge.
