#include <itkFFTPadImageFilter.h>

Detailed Description

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

Pad an image to make it suitable for an FFT transformation.

FFT filters usually requires a specific image size. The size is decomposed in several prime factors, and the filter only supports prime factors up to a maximum value. This filter automatically finds the greatest prime factor required by the available implementation and pads the input appropriately.

This code was adapted from the Insight Journal contribution [66].

◆ CreateAnother()

template<typename TInputImage, typename TOutputImage = TInputImage>

virtual::itk::LightObject::Pointer itk::FFTPadImageFilter< 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.

◆ GenerateOutputInformation()

template<typename TInputImage, typename TOutputImage = TInputImage>

void itk::FFTPadImageFilter< TInputImage, TOutputImage >::GenerateOutputInformation ( )

overrideprotectedvirtual

Generate the information describing the output data. The default implementation of this method will copy information from the input to the output. A filter may override this method if its output will have different information than its input. For instance, a filter that shrinks an image will need to provide an implementation for this method that changes the spacing of the pixels. Such filters should call their superclass' implementation of this method prior to changing the information values they need (i.e. GenerateOutputInformation() should call Superclass::GenerateOutputInformation() prior to changing the information.

Reimplemented from itk::ProcessObject.

◆ GetSizeGreatestPrimeFactor()

template<typename TInputImage, typename TOutputImage = TInputImage>

virtual SizeValueType itk::FFTPadImageFilter< TInputImage, TOutputImage >::GetSizeGreatestPrimeFactor ( ) const

virtual

Set/Get the greatest prime factor allowed on the size of the padded image.

The filter increases the dimensional sizes of the image to reach a size with the greatest prime factor smaller or equal to the specified value. The default value is obtained from the ForwardFFTImageFilter, which is 13 for FFTW (7 with cuFFTW) and 11 for PocketFFT.

A greatest prime factor of 2 produces a size which is a power of 2. A greatest prime factor of 1 or less - typically 0 - disable the extra padding.

◆ New()

Standard New method.

template<typename TInputImage, typename TOutputImage = TInputImage>

void itk::FFTPadImageFilter< TInputImage, TOutputImage >::PrintSelf	(	std::ostream &	os,
		Indent	indent ) const

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::LightObject.

◆ SetSizeGreatestPrimeFactor()

template<typename TInputImage, typename TOutputImage = TInputImage>

virtual void itk::FFTPadImageFilter< TInputImage, TOutputImage >::SetSizeGreatestPrimeFactor ( SizeValueType _arg )

virtual

Set/Get the greatest prime factor allowed on the size of the padded image.

The filter increases the dimensional sizes of the image to reach a size with the greatest prime factor smaller or equal to the specified value. The default value is obtained from the ForwardFFTImageFilter, which is 13 for FFTW (7 with cuFFTW) and 11 for PocketFFT.

A greatest prime factor of 2 produces a size which is a power of 2. A greatest prime factor of 1 or less - typically 0 - disable the extra padding.
