#include <itkDiscreteGaussianImageFilter.h>

Detailed Description

template<typename TInputImage, typename TOutputImage = TInputImage>
class itk::DiscreteGaussianImageFilter< TInputImage, TOutputImage >

Blurs an image by separable convolution with discrete gaussian kernels. This filter performs Gaussian blurring by separable convolution of an image and a discrete Gaussian operator (kernel).

The Gaussian operator used here was described by Tony Lindeberg in [71]. The Gaussian kernel used here was designed so that smoothing and derivative operations commute after discretization.

The variance or standard deviation (sigma) will be evaluated as pixel units if SetUseImageSpacing is off (false) or as physical units if SetUseImageSpacing is on (true, default). The variance can be set independently in each dimension.

When the Gaussian kernel is small, this filter tends to run faster than itk::RecursiveGaussianImageFilter.

◆ CreateAnother()

template<typename TInputImage, typename TOutputImage = TInputImage>

virtual::itk::LightObject::Pointer itk::DiscreteGaussianImageFilter< TInputImage, TOutputImage >::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::LightObject.

Reimplemented in itk::FFTDiscreteGaussianImageFilter< TInputImage, TOutputImage >.

◆ GenerateData()

template<typename TInputImage, typename TOutputImage = TInputImage>

void itk::DiscreteGaussianImageFilter< TInputImage, TOutputImage >::GenerateData ( )

overrideprotectedvirtual

Standard pipeline method. While this class does not implement a ThreadedGenerateData(), its GenerateData() delegates all calculations to an NeighborhoodOperatorImageFilter. Since the NeighborhoodOperatorImageFilter is multithreaded, this filter is multithreaded by default.

Reimplemented from itk::ProcessObject.

Reimplemented in itk::FFTDiscreteGaussianImageFilter< TInputImage, TOutputImage >.

◆ GenerateInputRequestedRegion()

template<typename TInputImage, typename TOutputImage = TInputImage>

void itk::DiscreteGaussianImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion ( )

overrideprotectedvirtual

DiscreteGaussianImageFilter needs a larger input requested region than the output requested region (larger by the size of the Gaussian kernel). As such, DiscreteGaussianImageFilter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model.

See also: ImageToImageFilter::GenerateInputRequestedRegion()

Reimplemented from itk::ProcessObject.

Reimplemented in itk::FFTDiscreteGaussianImageFilter< TInputImage, TOutputImage >.

◆ GenerateKernel()

template<typename TInputImage, typename TOutputImage = TInputImage>

void itk::DiscreteGaussianImageFilter< TInputImage, TOutputImage >::GenerateKernel	(	const unsigned int	dimension,
		KernelType &	oper ) const

protected

Build a directional kernel to match user specifications

◆ GetFilterDimensionality()

template<typename TInputImage, typename TOutputImage = TInputImage>

virtual unsigned int itk::DiscreteGaussianImageFilter< TInputImage, TOutputImage >::GetFilterDimensionality ( ) const

virtual

Set the number of dimensions to smooth. Defaults to the image dimension. Can be set to less than ImageDimension, smoothing all the dimensions less than FilterDimensionality. For instance, to smooth the slices of a volume without smoothing in Z, set the FilterDimensionality to 2.

◆ GetInputBoundaryCondition()

template<typename TInputImage, typename TOutputImage = TInputImage>

virtual BoundaryConditionType * itk::DiscreteGaussianImageFilter< TInputImage, TOutputImage >::GetInputBoundaryCondition ( ) const

virtual

Set/get the boundary condition.
