Detailed Description

template<unsigned int VSplineOrder = 3>
class itk::BSplineSecondOrderDerivativeKernelFunction2< VSplineOrder >

Derivative of a B-spline kernel used for density estimation and nonparametric regression.

This class encapsulates the derivative of a B-spline kernel for density estimation or nonparametric regression. See documentation for KernelFunction for more details.

This class is templated over the spline order.

Warning

Evaluate is only implemented for spline order 1 to 4
