Member Function Documentation

◆ AddObserver()

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.

◆ compute()

virtual void itk::MultipleValuedVnlCostFunctionAdaptor::compute ( const InternalParametersType x,
InternalMeasureType ff,
InternalDerivativeType g 
)
virtual

Delegate computation of value and gradient to the costFunction.

◆ ConvertExternalToInternalGradient()

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

Convert external derivative measures into internal type

◆ ConvertExternalToInternalMeasures()

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

Convert external measures into internal type

◆ f()

void itk::MultipleValuedVnlCostFunctionAdaptor::f ( const InternalParametersType inparameters,
InternalMeasureType measures 
)
override

Delegate computation of the value to the CostFunction.

◆ GetCachedCurrentParameters()

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

◆ GetCachedDerivative()

const DerivativeType& itk::MultipleValuedVnlCostFunctionAdaptor::GetCachedDerivative ( ) const

◆ GetCachedValue()

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.

◆ GetCostFunction()

const MultipleValuedCostFunction* itk::MultipleValuedVnlCostFunctionAdaptor::GetCostFunction ( ) const
inline

Get the CostFunction deriving from MultipleValuedCostFunction

Definition at line 73 of file itkMultipleValuedVnlCostFunctionAdaptor.h.

◆ GetInverseScales()

virtual const ScalesType& itk::MultipleValuedVnlCostFunctionAdaptor::GetInverseScales ( ) const
privatevirtual

Get current parameters scaling.

◆ GetUseGradient()

bool itk::MultipleValuedVnlCostFunctionAdaptor::GetUseGradient ( ) const

◆ gradf()

void itk::MultipleValuedVnlCostFunctionAdaptor::gradf ( const InternalParametersType inparameters,
InternalDerivativeType gradient 
)
override

Delegate computation of the gradient to the costFunction.

◆ ReportIteration()

void itk::MultipleValuedVnlCostFunctionAdaptor::ReportIteration ( const EventObject event) const
protected

This method is intended to be called by the derived classes in order to notify of an iteration event to any Command/Observers

◆ SetCostFunction()

void itk::MultipleValuedVnlCostFunctionAdaptor::SetCostFunction ( MultipleValuedCostFunction costFunction)
inline

Set the CostFunction deriving from MultipleValuedCostFunction

Definition at line 66 of file itkMultipleValuedVnlCostFunctionAdaptor.h.

◆ SetScales()

void itk::MultipleValuedVnlCostFunctionAdaptor::SetScales ( const ScalesType scales)

Set current parameters scaling.

◆ SetUseGradient()

void itk::MultipleValuedVnlCostFunctionAdaptor::SetUseGradient ( bool  )

Define if the Cost function should provide a customized Gradient computation or the gradient can be computed internally using a default approach

◆ UseGradientOff()

void itk::MultipleValuedVnlCostFunctionAdaptor::UseGradientOff ( )
inline

Definition at line 110 of file itkMultipleValuedVnlCostFunctionAdaptor.h.

◆ UseGradientOn()

void itk::MultipleValuedVnlCostFunctionAdaptor::UseGradientOn ( )
inline

Definition at line 105 of file itkMultipleValuedVnlCostFunctionAdaptor.h.
