itk::ScaledSingleValuedCostFunction Class Reference

#include <itkScaledSingleValuedCostFunction.h>

Detailed Description

A cost function that applies a scaling to another cost function.

This class can be used to adapt an existing, badly scaled, cost function.

By default it does not apply any scaling. Use the method SetUseScales(true) to enable the use of scales.

Member Function Documentation

virtual void itk::ScaledSingleValuedCostFunction::ConvertScaledToUnscaledParameters ( ParametersType parameters) const
virtual

Convert the parameters from scaled to unscaled: x = y/s.

virtual void itk::ScaledSingleValuedCostFunction::ConvertUnscaledToScaledParameters ( ParametersType parameters) const
virtual

Convert the parameters from unscaled to scaled: y = x*s.

virtual const char* itk::ScaledSingleValuedCostFunction::GetClassName ( ) const
virtual

Run-time type information (and related methods).

virtual void itk::ScaledSingleValuedCostFunction::GetDerivative ( const ParametersType parameters,
DerivativeType derivative 
) const
virtual

Divide the parameters by the scales, call the GetDerivative routine of the unscaled cost function and divide the resulting derivative by the scales.

virtual bool itk::ScaledSingleValuedCostFunction::GetNegateCostFunction ( ) const
virtual

Get the flag to negate the cost function or not.

virtual NumberOfParametersType itk::ScaledSingleValuedCostFunction::GetNumberOfParameters ( void  ) const
virtual

Ask the UnscaledCostFunction how many parameters it has.

virtual const ScalesType& itk::ScaledSingleValuedCostFunction::GetScales ( )
virtual

Get the scales.

virtual const ScalesType& itk::ScaledSingleValuedCostFunction::GetSquaredScales ( )
virtual

The ITK convention is to use the squared scales. This function returns the squared actual scales.

virtual Superclass* itk::ScaledSingleValuedCostFunction::GetUnscaledCostFunction ( )
virtual

Get the cost function that needs scaling.

virtual bool itk::ScaledSingleValuedCostFunction::GetUseScales ( ) const
virtual

Get the flag to use scales or not.

virtual MeasureType itk::ScaledSingleValuedCostFunction::GetValue ( const ParametersType parameters) const
virtual

Divide the parameters by the scales and call the GetValue routine of the unscaled cost function.

virtual void itk::ScaledSingleValuedCostFunction::GetValueAndDerivative ( const ParametersType parameters,
MeasureType value,
DerivativeType derivative 
) const
virtual

Same procedure as in GetValue and GetDerivative.

virtual void itk::ScaledSingleValuedCostFunction::NegateCostFunctionOff ( )
virtual
virtual void itk::ScaledSingleValuedCostFunction::NegateCostFunctionOn ( )
virtual

Set the flag to negate the cost function or not.

static Pointer itk::ScaledSingleValuedCostFunction::New ( )
static

Method for creation through the object factory.

void itk::ScaledSingleValuedCostFunction::operator= ( const Self )
private

The private copy constructor.

void itk::ScaledSingleValuedCostFunction::PrintSelf ( std::ostream &  os,
Indent  indent 
) const
protected

PrintSelf.

virtual void itk::ScaledSingleValuedCostFunction::SetNegateCostFunction ( bool  _arg)
virtual

Set the flag to negate the cost function or not.

virtual void itk::ScaledSingleValuedCostFunction::SetScales ( const ScalesType scales)
virtual

Set the scales. Also computes the squared scales, just in case users call GetSquaredScales (for compatibility with the ITK convention).

virtual void itk::ScaledSingleValuedCostFunction::SetSquaredScales ( const ScalesType squaredScales)
virtual

The ITK convention is to use the squared scales. This function takes the square root of the input scales and sets them as the the actual scales

virtual void itk::ScaledSingleValuedCostFunction::SetUnscaledCostFunction ( Superclass _arg)
virtual

Set the cost function that needs scaling.

virtual void itk::ScaledSingleValuedCostFunction::SetUseScales ( bool  _arg)
virtual

Set the flag to use scales or not.
