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

◆ AddObserver()

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.

◆ compute()

void itk::SingleValuedVnlCostFunctionAdaptorv4::compute ( const InternalParametersType x,
InternalMeasureType fun,
InternalDerivativeType g 
)
override

Delegate computation of value and gradient to the costFunction.

◆ ConvertExternalToInternalGradient()

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

Convert external derivative measures into internal type

◆ f()

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

Delegate computation of the value to the CostFunction.

◆ GetCachedCurrentParameters()

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

Return the parameters directly from the assigned metric.

◆ GetCachedDerivative()

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

◆ GetCachedValue()

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.

◆ GetCostFunction()

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

Get the CostFunction deriving from SingleValuedCostFunction

Definition at line 74 of file itkSingleValuedVnlCostFunctionAdaptorv4.h.

References m_ObjectMetric.

◆ gradf()

void itk::SingleValuedVnlCostFunctionAdaptorv4::gradf ( const InternalParametersType inparameters,
InternalDerivativeType gradient 
)
override

Delegate computation of the gradient to the costFunction.

◆ ReportIteration()

void itk::SingleValuedVnlCostFunctionAdaptorv4::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::SingleValuedVnlCostFunctionAdaptorv4::SetCostFunction ( ObjectToObjectMetricBase costFunction)
inline

Set the CostFunction deriving from SingleValuedCostFunction

Definition at line 67 of file itkSingleValuedVnlCostFunctionAdaptorv4.h.

References m_ObjectMetric.

◆ SetScales()

void itk::SingleValuedVnlCostFunctionAdaptorv4::SetScales ( const ScalesType scales)

Set current parameters scaling.
