Member Function Documentation

unsigned long itk::MultipleValuedVnlCostFunctionAdaptor::AddObserver ( const EventObject event,
) 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 

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

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

Delegate computation of the value to the CostFunction.

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

Get the CostFunction deriving from MultipleValuedCostFunction

Definition at line 72 of file itkMultipleValuedVnlCostFunctionAdaptor.h.

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

Get current parameters scaling.

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

Delegate computation of the gradient to the costFunction.

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

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

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

Set the CostFunction deriving from MultipleValuedCostFunction

Definition at line 68 of file itkMultipleValuedVnlCostFunctionAdaptor.h.

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

Set current parameters scaling.

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

void itk::MultipleValuedVnlCostFunctionAdaptor::UseGradientOff ( )

Definition at line 104 of file itkMultipleValuedVnlCostFunctionAdaptor.h.

void itk::MultipleValuedVnlCostFunctionAdaptor::UseGradientOn ( )
