Detailed Description

perform b-spline interpolation on images

vtkImageBSplineInterpolator can be used to perform b-spline interpolation on images that have been filtered with vtkImageBSplineCoefficients. The b-spline interpolants provide the maximum possible degree of continuity for a given kernel size, but require that the image data be pre-filtered to generate b-spline coefficients before the interpolation is performed. Interpolating data that has not been pre-filtered will give incorrect results.

If the data is going to be sampled on a regular grid, then the interpolation weights can be precomputed.

A matrix must be supplied that provides a transformation between the provided extent and the structured coordinates of the input.
