#include <itkRelabelComponentImageFilter.h>

Detailed Description

template<typename TInputImage, typename TOutputImage>
class itk::RelabelComponentImageFilter< TInputImage, TOutputImage >

Relabel the components in an image such that consecutive labels are used.

RelabelComponentImageFilter remaps the labels associated with the objects in an image (as from the output of ConnectedComponentImageFilter) such that the label numbers are consecutive with no gaps between the label numbers used. By default, the relabeling will also sort the labels based on the size of the object: the largest object will have label #1, the second largest will have label #2, etc. If two labels have the same size their initial order is kept. The sorting by size can be disabled using SetSortByObjectSize.

Label #0 is assumed to be the background and is left unaltered by the relabeling.

RelabelComponentImageFilter is typically used on the output of the ConnectedComponentImageFilter for those applications that want to extract the largest object or the "k" largest objects. Any particular object can be extracted from the relabeled output using a BinaryThresholdImageFilter. A group of objects can be extracted from the relabeled output using a ThresholdImageFilter.

Once all the objects are relabeled, the application can query the number of objects and the size of each object. Object sizes are returned in a vector. The size of the background is not calculated. So the size of object #1 is GetSizeOfObjectsInPixels()[0], the size of object #2 is GetSizeOfObjectsInPixels()[1], etc.

If user sets a minimum object size, all objects with fewer pixels than the minimum will be discarded, so that the number of objects reported will be only those remaining. The GetOriginalNumberOfObjects method can be called to find out how many objects were present before the small ones were discarded.

RelabelComponentImageFilter can be run as an "in place" filter, where it will overwrite its output. The default is run out of place (or generate a separate output). "In place" operation can be controlled via methods in the superclass, InPlaceImageFilter::InPlaceOn() and InPlaceImageFilter::InPlaceOff().

◆ GenerateData()

template<typename TInputImage , typename TOutputImage >

◆ GenerateInputRequestedRegion()

template<typename TInputImage , typename TOutputImage >

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

overrideprotectedvirtual

RelabelComponentImageFilter needs the entire input. Therefore it must provide an implementation GenerateInputRequestedRegion().

Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

◆ GetMinimumObjectSize()

template<typename TInputImage , typename TOutputImage >

virtual ObjectSizeType itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::GetMinimumObjectSize ( ) const

virtual

Get the caller-defined minimum size of an object in pixels. If the caller has not set the minimum, 0 will be returned, which is to be interpreted as meaning that no minimum exists, and all objects in the original label map will be passed through to the output.

◆ GetNameOfClass()

template<typename TInputImage , typename TOutputImage >

const char* itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::GetNameOfClass ( ) const

overridevirtual

Run-time type information (and related methods)

Reimplemented from itk::InPlaceImageFilter< TInputImage, TOutputImage >.

◆ GetNumberOfObjects()

template<typename TInputImage , typename TOutputImage >

virtual SizeValueType itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::GetNumberOfObjects ( ) const

virtual

Get the number of objects in the image. This information is only valid after the filter has executed.

◆ GetNumberOfObjectsToPrint()

template<typename TInputImage , typename TOutputImage >

virtual const SizeValueType& itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::GetNumberOfObjectsToPrint ( ) const

virtual

Get/Set the number of objects enumerated and described when the filter is printed.

◆ GetOriginalNumberOfObjects()

template<typename TInputImage , typename TOutputImage >

virtual SizeValueType itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::GetOriginalNumberOfObjects ( ) const

virtual

Get the original number of objects in the image before small objects were discarded. This information is only valid after the filter has executed. If the caller has not specified a minimum object size, OriginalNumberOfObjects is the same as NumberOfObjects.

◆ GetSizeOfObjectInPhysicalUnits()

template<typename TInputImage , typename TOutputImage >

float itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::GetSizeOfObjectInPhysicalUnits ( LabelType obj ) const

inline

Definition at line 229 of file itkRelabelComponentImageFilter.h.

◆ GetSizeOfObjectInPixels()

template<typename TInputImage , typename TOutputImage >

ObjectSizeType itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::GetSizeOfObjectInPixels ( LabelType obj ) const

template<typename TInputImage , typename TOutputImage >

virtual bool itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::GetSortByObjectSize ( ) const

virtual

Controls whether the object labels are sorted by size. If false, initial order of labels is kept.

◆ New()

template<typename TInputImage , typename TOutputImage >

static Pointer itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::New ( )

static

Method for creation through the object factory.

◆ ParallelComputeLabels()

◆ PrintSelf()

template<typename TInputImage , typename TOutputImage >

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

overrideprotectedvirtual

Standard printself method

Reimplemented from itk::InPlaceImageFilter< TInputImage, TOutputImage >.

◆ SetMinimumObjectSize()

template<typename TInputImage , typename TOutputImage >

virtual void itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::SetMinimumObjectSize ( ObjectSizeType _arg )

virtual

Set the minimum size in pixels for an object. All objects smaller than this size will be discarded and will not appear in the output label map. NumberOfObjects will count only the objects whose pixel counts are greater than or equal to the minimum size. Call GetOriginalNumberOfObjects to find out how many objects were present in the original label map.

◆ SetNumberOfObjectsToPrint()

template<typename TInputImage , typename TOutputImage >

virtual void itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::SetNumberOfObjectsToPrint ( SizeValueType _arg )

virtual

Get/Set the number of objects enumerated and described when the filter is printed.

◆ SetSortByObjectSize()

template<typename TInputImage , typename TOutputImage >

virtual void itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::SetSortByObjectSize ( bool _arg )

virtual

Controls whether the object labels are sorted by size. If false, initial order of labels is kept.

◆ SortByObjectSizeOn()

template<typename TInputImage , typename TOutputImage >

virtual void itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::SortByObjectSizeOn ( )

virtual

Controls whether the object labels are sorted by size. If false, initial order of labels is kept.
