Detailed Description

template<typename TInputImage, typename TOutputImage>
class itk::GPUDiscreteGaussianImageFilter< 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). GPUNeighborhoodOperatorImageFilter is used to compute 1D directional discrete Gaussian filtering for each axis.

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 >

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

GenerateInputRequestedRegion()

template<typename TInputImage , typename TOutputImage >

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

overridevirtual

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.
