#include <itkBSplineResampleImageFunction.h>

Detailed Description

template<typename TImageType, typename TCoordRep = float>
class itk::BSplineResampleImageFunction< TImageType, TCoordRep >

Resample image intensity from a BSpline coefficient image.

This class resample the image intensity at a non-integer position from the input BSpline coefficient image.

Spline order may be from 0 to 5.

In ITK, BSpline coefficient can be generated using a BSplineDecompositionImageFilter. Using this image function in conjunction with ResampleImageFunction allows the reconstruction of the original image at different resolution and size.
