Detailed Description

template<unsigned int TDimension = 3>
class itk::NonUniformBSpline< TDimension >

BSpline with nonuniform knot spacing.

Warning
This class was taken from an earlier ITK version and slightly modified. The original itkNonUniformBSpline is deprecated in ITK 4.3. Currently, the mitkItkNonUniformBSpline is only used inside the virtual tracking device.

This class is a bspline with nonuniform knot spacing. The use can specify a set of points and a set of knots and the spline will attempt to find the control points which will cause the spline to interpolate the points.
