Detailed Description

This class is an Adaptor that allows to pass itk::ObjectToObjectMetricBase objects to vnl_optimizers expecting a vnl_cost_function. For use in the ITKv4 registration framework.

This class returns a single value.

Member Function Documentation

unsigned long itk::SingleValuedVnlCostFunctionAdaptorv4::AddObserver	(	const EventObject &	event,
		Command *
	)		const

This AddObserver method allows to simulate that this class derives from an itkObject for the purpose of reporting iteration events. The goal of this method is to allow ITK-vnl optimizer adaptors to get iteration events despite the fact that VNL does not provide callbacks.

void itk::SingleValuedVnlCostFunctionAdaptorv4::compute	(	const InternalParametersType &	x,
		InternalMeasureType *	f,
		InternalDerivativeType *	g
	)

override

Delegate computation of value and gradient to the costFunction.

void itk::SingleValuedVnlCostFunctionAdaptorv4::ConvertExternalToInternalGradient	(	const DerivativeType &	input,
		InternalDerivativeType &	output
	)		const

Convert external derviative measures into internal type

InternalMeasureType itk::SingleValuedVnlCostFunctionAdaptorv4::f ( const InternalParametersType & inparameters )

override

Delegate computation of the value to the CostFunction.

const ParametersType& itk::SingleValuedVnlCostFunctionAdaptorv4::GetCachedCurrentParameters ( ) const

Return the parameters directly from the assigned metric.

virtual const DerivativeType& itk::SingleValuedVnlCostFunctionAdaptorv4::GetCachedDerivative ( ) const

virtual

virtual const MeasureType& itk::SingleValuedVnlCostFunctionAdaptorv4::GetCachedValue ( ) const

virtual

Return the value of the last evaluation to the value of the cost function. Note that this method DOES NOT triggers a computation of the function or the derivatives, it only returns previous values. Therefore the values here are only valid after you invoke the f() or gradf() methods.

const ObjectToObjectMetricBase* itk::SingleValuedVnlCostFunctionAdaptorv4::GetCostFunction ( ) const

inline

Get the CostFunction deriving from SingleValuedCostFunction
