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::LightObject.

◆ SetNormalizeAcrossScale()

template<typename TInputImage, typename TOutputImage = TInputImage>

void itk::GradientMagnitudeRecursiveGaussianImageFilter< TInputImage, TOutputImage >::SetNormalizeAcrossScale ( bool normalize )

Set/Get the normalization factor that will be used for the Gaussian.

 \sa  RecursiveGaussianImageFilter::SetNormalizeAcrossScale

◆ SetNumberOfWorkUnits()

template<typename TInputImage, typename TOutputImage = TInputImage>

void itk::GradientMagnitudeRecursiveGaussianImageFilter< TInputImage, TOutputImage >::SetNumberOfWorkUnits ( ThreadIdType _arg )

overridevirtual

Get/Set the number of work units to create when executing.

Reimplemented from itk::ProcessObject.

◆ SetSigma()

template<typename TInputImage, typename TOutputImage = TInputImage>

void itk::GradientMagnitudeRecursiveGaussianImageFilter< TInputImage, TOutputImage >::SetSigma ( RealType sigma )

Set/Get Sigma value. Sigma is measured in the units of image spacing.
