Member Function Documentation

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

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

template<typename TInputImage >
virtual::itk::LightObject::Pointer itk::WarpHarmonicEnergyCalculator< TInputImage >::CreateAnother ( ) 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.

protected
template<typename TInputImage >
virtual const WeightsType& itk::WarpHarmonicEnergyCalculator< TInputImage >::GetDerivativeWeights ( ) const
virtual

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

template<typename TInputImage >
virtual double itk::WarpHarmonicEnergyCalculator< TInputImage >::GetHarmonicEnergy ( ) const
virtual

Return the smoothness value.

template<typename TInputImage >
virtual const char* itk::WarpHarmonicEnergyCalculator< TInputImage >::GetNameOfClass ( ) const
virtual

Run-time type information (and related methods).

Reimplemented from itk::Object.

template<typename TInputImage >
virtual const RadiusType& itk::WarpHarmonicEnergyCalculator< TInputImage >::GetNeighborhoodRadius ( ) const

Get/Set the neighborhood radius used for gradient computation

template<typename TInputImage >

Method for creation through the object factory.

template<typename TInputImage >
virtual void itk::WarpHarmonicEnergyCalculator< TInputImage >::PrintSelf ( std::ostream &  os,
Indent  indent

overrideprotectedvirtual

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

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

template<typename TInputImage >
virtual void itk::WarpHarmonicEnergyCalculator< TInputImage >::SetImage ( const ImageType _arg)
virtual

Set the input image.

template<typename TInputImage >
virtual void itk::WarpHarmonicEnergyCalculator< TInputImage >::SetNeighborhoodRadius ( RadiusType  _arg)
protectedvirtual

Get/Set the neighborhood radius used for gradient computation

template<typename TInputImage >
void itk::WarpHarmonicEnergyCalculator< TInputImage >::SetRegion ( const RegionType region)

Set the region over which the values will be computed

template<typename 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. When set to "On", 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. Setting the value to "Off" resets the derivative weights to ignore image spacing. Use this option if you want to calculate the Jacobian determinant in the image space. Default value is "On".
