Member Function Documentation

template<class TInputImage >

void itk::WarpHarmonicEnergyCalculator< TInputImage >::Compute ( void )

Compute the minimum and maximum values of intensity of the input image.

template<class TInputImage >

virtual::itk::LightObject::Pointer itk::WarpHarmonicEnergyCalculator< TInputImage >::CreateAnother ( void ) const [virtual]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

template<class TInputImage >

double itk::WarpHarmonicEnergyCalculator< TInputImage >::EvaluateAtNeighborhood ( ConstNeighborhoodIteratorType & it ) const [protected]

template<class TInputImage >

virtual const WeightsType& itk::WarpHarmonicEnergyCalculator< TInputImage >::GetDerivativeWeights ( ) [virtual]

Directly Set/Get the array of weights used in the gradient calculations. Note that calling UseImageSpacingOn will clobber these values.

template<class TInputImage >

virtual double itk::WarpHarmonicEnergyCalculator< TInputImage >::GetHarmonicEnergy ( ) const [virtual]

Return the smoothness value.

template<class TInputImage >

virtual const char* itk::WarpHarmonicEnergyCalculator< TInputImage >::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::Object.

template<class TInputImage >

virtual const RadiusType& itk::WarpHarmonicEnergyCalculator< TInputImage >::GetNeighborhoodRadius ( ) [protected, virtual]

Get/Set the neighborhood radius used for gradient computation

template<class TInputImage >

virtual bool itk::WarpHarmonicEnergyCalculator< TInputImage >::GetUseImageSpacing ( ) const [virtual]

template<class TInputImage >

static Pointer itk::WarpHarmonicEnergyCalculator< TInputImage >::New ( ) [static]

Method for creation through the object factory.

Reimplemented from itk::Object.

template<class TInputImage >

void itk::WarpHarmonicEnergyCalculator< TInputImage >::operator= ( const Self & ) [private]

Mutex lock to protect modification to the reference count

Reimplemented from itk::Object.

template<class TInputImage >

void itk::WarpHarmonicEnergyCalculator< TInputImage >::PrintSelf	(	std::ostream &	os,
		Indent	indent
	)		const `[protected, virtual]`

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::Object.

template<class TInputImage >

virtual void itk::WarpHarmonicEnergyCalculator< TInputImage >::SetDerivativeWeights ( WeightsType _arg ) [virtual]

Directly Set/Get the array of weights used in the gradient calculations. Note that calling UseImageSpacingOn will clobber these values.

template<class TInputImage >

virtual void itk::WarpHarmonicEnergyCalculator< TInputImage >::SetImage ( const ImageType * _arg ) [virtual]

Set the input image.

template<class TInputImage >

virtual void itk::WarpHarmonicEnergyCalculator< TInputImage >::SetNeighborhoodRadius ( RadiusType _arg ) [protected, virtual]

Get/Set the neighborhood radius used for gradient computation

Set the region over which the values will be computed

template<class TInputImage >

void itk::WarpHarmonicEnergyCalculator< TInputImage >::SetUseImageSpacing ( bool )

Set/Get whether or not the filter will use the spacing of the input image in its calculations

template<class TInputImage >

void itk::WarpHarmonicEnergyCalculator< TInputImage >::SetUseImageSpacingOff ( ) [inline]

Reset the derivative weights to ignore image spacing. Use this option if you want to calculate the Jacobian determinant in the image space. Default is ImageSpacingOn.

Definition at line 102 of file itkWarpHarmonicEnergyCalculator.h.

template<class TInputImage >

void itk::WarpHarmonicEnergyCalculator< TInputImage >::SetUseImageSpacingOn ( ) [inline]

Set the derivative weights according to the spacing of the input image (1/spacing). Use this option if you want to calculate the Jacobian determinant in the space in which the data was acquired.
