Member Function Documentation

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

Run-time type information (and related methods). Reimplemented from itk::Object. Reimplemented in itk::ImageToImageMetric< TFixedImage, TMovingImage >, itk::MeanSquaresImageToImageMetric< TFixedImage, TMovingImage >, itk::MRIBiasEnergyFunction< TImage, TImageMask, TBiasField >, itk::MutualInformationImageToImageMetric< TFixedImage, TMovingImage >, itk::NormalizedCorrelationImageToImageMetric< TFixedImage, TMovingImage >, itk::PatternIntensityImageToImageMetric< TFixedImage, TMovingImage >, itk::MultipleValuedCostFunction, itk::SingleValuedCostFunction, and itk::Statistics::GoodnessOfFitMixtureModelCostFunction< TInputSample >.

virtual unsigned int itk::CostFunction::GetNumberOfParameters (  void    )  const [pure virtual]

Return the number of parameters required to compute this cost function. This method MUST be overloaded by derived classes. Implemented in itk::ImageToImageMetric< TFixedImage, TMovingImage >, itk::MRIBiasEnergyFunction< TImage, TImageMask, TBiasField >, and itk::Statistics::GoodnessOfFitMixtureModelCostFunction< TInputSample >.

void itk::CostFunction::PrintSelf (  std::ostream &    os, Indent    indent )  const [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::ImageToImageMetric< TFixedImage, TMovingImage >, itk::MutualInformationImageToImageMetric< TFixedImage, TMovingImage >, itk::PatternIntensityImageToImageMetric< TFixedImage, TMovingImage >, and itk::Statistics::GoodnessOfFitMixtureModelCostFunction< TInputSample >.
