#include <itkBSplineControlPointImageFunction.h>

Detailed Description

template<typename TInputImage, typename TCoordinate = double>
class itk::BSplineControlPointImageFunction< TInputImage, TCoordinate >

Evaluate a B-spline object given a grid of control points.

The output of the class itkBSplineScatteredDataPointSetToImageFilter: is a control point grid defining a B-spline object. This class is used to hold various routines meant to operate on that control point grid. In addition to specifying the control point grid as the input, the user must also supply the spline order and the parametric domain (i.e. size, domain, origin, spacing).

Operations include

Evaluation of the B-spline object at any point in the domain.
Evaluation of the gradient of the B-spline object at any point in the domain.
Evaluation of the Hessian of the B-spline object at any point in the domain.
