Member Function Documentation

unsigned long itk::MultipleValuedVnlCostFunctionAdaptor::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.

virtual void itk::MultipleValuedVnlCostFunctionAdaptor::compute	(	const InternalParametersType &	x,
		InternalMeasureType *	f,
		InternalDerivativeType *	g
	)			[virtual]

Delegate computation of value and gradient to the costFunction.

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

Convert external derviative measures into internal type

void itk::MultipleValuedVnlCostFunctionAdaptor::ConvertExternalToInternalMeasures	(	const MeasureType &	input,
		InternalMeasureType &	output
	)

Convert external measures into internal type

virtual void itk::MultipleValuedVnlCostFunctionAdaptor::f	(	const InternalParametersType &	inparameters,
		InternalMeasureType &	measures
	)			[virtual]

Delegate computation of the value to the CostFunction.

const ParametersType& itk::MultipleValuedVnlCostFunctionAdaptor::GetCachedCurrentParameters

(

)

const

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 DerivativeType& itk::MultipleValuedVnlCostFunctionAdaptor::GetCachedDerivative

(

)

const

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 MeasureType& itk::MultipleValuedVnlCostFunctionAdaptor::GetCachedValue

(

)

const

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 MultipleValuedCostFunction* itk::MultipleValuedVnlCostFunctionAdaptor::GetCostFunction

bool itk::MultipleValuedVnlCostFunctionAdaptor::GetUseGradient

(

virtual void itk::MultipleValuedVnlCostFunctionAdaptor::gradf	(	const InternalParametersType &	inparameters,
