Detailed Description

Kernel used for density estimation and nonparameteric regression.

This class encapsulates the smoothing kernel used for statistical density estimation and nonparameteric regression. The basic idea of the kernel approach is to weight observations by a smooth function (the kernel) to created a smoothed approximation.

Member Function Documentation

virtual double itk::KernelFunction::Evaluate (  const double &    u )  const [pure virtual]

Evaluate the function. Subclasses must implement this. Implemented in itk::BSplineDerivativeKernelFunction< VSplineOrder >, itk::BSplineKernelFunction< VSplineOrder >, and itk::GaussianKernelFunction.

virtual const char* itk::KernelFunction::GetClassName (    )  const [virtual]

Run-time type information (and related methods). Reimplemented from itk::FunctionBase< double, double >. Reimplemented in itk::BSplineDerivativeKernelFunction< VSplineOrder >, itk::BSplineKernelFunction< VSplineOrder >, and itk::GaussianKernelFunction.

void itk::KernelFunction::PrintSelf (  std::ostream &    os, Indent    indent )  const [inline, protected, virtual]

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from itk::Object. Reimplemented in itk::BSplineDerivativeKernelFunction< VSplineOrder >, itk::BSplineKernelFunction< VSplineOrder >, and itk::GaussianKernelFunction. Definition at line 57 of file itkKernelFunction.h.
