itk::FrequencyImageRegionConstIteratorWithIndex< TImage > Class Template Reference

#include <itkFrequencyImageRegionConstIteratorWithIndex.h>

Detailed Description

template<typename TImage>
class itk::FrequencyImageRegionConstIteratorWithIndex< TImage >

A multi-dimensional iterator templated over image type that walks pixels within a region and is specialized to keep track of its image index location.

This class is a specialization of ImageRegionConstIteratorWithIndex, adding method GetFrequencyBins to give the frequency bins corresponding to image indices, and GetFrequency to get the frequency of the bin.

This iterator assumes that the image is already in the frequency domain, so GetFrequencyBin is a wrap around GetIndex(), and GetFrequency is a wrap around Get().

For a different layout, use other frequency iterator.

Please see ImageRegionConstIteratorWithIndex for more information.

◆ Superclass

Constructor & Destructor Documentation

◆ FrequencyImageRegionConstIteratorWithIndex() [1/3]

template<typename TImage >
itk::FrequencyImageRegionConstIteratorWithIndex< TImage >::FrequencyImageRegionConstIteratorWithIndex ( )
inline

Default constructor. Needed since we provide a cast constructor.

Definition at line 101 of file itkFrequencyImageRegionConstIteratorWithIndex.h.

◆ FrequencyImageRegionConstIteratorWithIndex() [2/3]

template<typename TImage >
itk::FrequencyImageRegionConstIteratorWithIndex< TImage >::FrequencyImageRegionConstIteratorWithIndex ( const TImage *  ptr,
const RegionType region 
)
inline

Constructor establishes an iterator to walk a particular image and a particular region of that image.

Definition at line 109 of file itkFrequencyImageRegionConstIteratorWithIndex.h.

◆ FrequencyImageRegionConstIteratorWithIndex() [3/3]

template<typename TImage >
itk::FrequencyImageRegionConstIteratorWithIndex< TImage >::FrequencyImageRegionConstIteratorWithIndex ( const Superclass it)
inlineexplicit

Constructor that can be used to cast from an ImageIterator to an ImageRegionIteratorWithIndex. Many routines return an ImageIterator, but for a particular task, you may want an ImageRegionIteratorWithIndex. Rather than provide overloaded APIs that return different types of Iterators, itk returns ImageIterators and uses constructors to cast from an ImageIterator to a ImageRegionIteratorWithIndex.

Definition at line 121 of file itkFrequencyImageRegionConstIteratorWithIndex.h.

◆ GetFrequency()

template<typename TImage >
FrequencyType itk::FrequencyImageRegionConstIteratorWithIndex< TImage >::GetFrequency ( ) const
inline

◆ GetFrequencyBin()

template<typename TImage >
IndexType itk::FrequencyImageRegionConstIteratorWithIndex< TImage >::GetFrequencyBin ( ) const
inline

◆ GetFrequencyModuloSquare()

template<typename TImage >
FrequencyValueType itk::FrequencyImageRegionConstIteratorWithIndex< TImage >::GetFrequencyModuloSquare ( ) const
inline

◆ GetFrequencyOrigin()

template<typename TImage >
virtual const FrequencyType & itk::FrequencyImageRegionConstIteratorWithIndex< TImage >::GetFrequencyOrigin ( ) const
virtual

Origin of frequencies is set to be equal to m_Image->GetOrigin().

◆ GetFrequencySpacing()

template<typename TImage >
virtual const FrequencyType & itk::FrequencyImageRegionConstIteratorWithIndex< TImage >::GetFrequencySpacing ( ) const
virtual

This is the pixel width, or the bin size of the frequency in physical or world coordinates. In this case, frequency spacing is the same than the image spacing.

◆ Init()

template<typename TImage >
void itk::FrequencyImageRegionConstIteratorWithIndex< TImage >::Init ( )
inlineprivate

Set the frequency metadata. Called by constructors.
