Detailed Description

template<class TLabelObject>
class itk::LabelMap< TLabelObject >

Templated n-dimensional image to store labeled objects.

LabelMap is an image class specialized in storing the labeled images. It represent the image in a different way than itk::Image. Instead of storing the content of the image in an array of pixels values, it store the a collection of labeled objects, and a background value. This way of storing the content of the image allow an easy and efficient manipulation of the objects in the image.

The LabelMap shares a lot of methods with the itk::Image class. it make it usable as input or output of the itk::ImageToImageFilter for example. However the methods don't have the same complexity in the 2 classes, because of the different way to store the data. GetPixel() is run in constant time for example in itk::Image, but have a worst case complexity of O(L), where L is the number of lines in the image (imageSize[1] * imageSize[2] for a 3D image).

template<class TLabelObject >

void itk::LabelMap< TLabelObject >::AddLabelObject ( LabelObjectType * labelObject )

Add a label object to the image. If a label object already has the label, it is overiden.

unsigned long itk::Object::AddObserver	(	const EventObject &	event,
		Command *
	)			`[inherited]`

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

unsigned long itk::Object::AddObserver	(	const EventObject &	event,
		Command *
	)			const `[inherited]`

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

template<class TLabelObject >

virtual void itk::LabelMap< TLabelObject >::Allocate ( ) [virtual]

Reimplemented from itk::ImageBase< ::itk::GetImageDimension< TLabelObject >::ImageDimension >.

static void itk::LightObject::BreakOnError ( ) [static, inherited]

This method is called when itkExceptionMacro executes. It allows the debugger to break on error.

template<class TLabelObject >

void itk::LabelMap< TLabelObject >::ClearLabels ( )

Remove all the labels in the image

IndexType itk::ImageBase< VImageDimension >::ComputeIndex ( OffsetValueType offset ) const [inline, inherited]

Compute the index of the pixel at a specified offset from the beginning of the buffered region. Bounds checking is not performed. Thus, the computed index could be outside the BufferedRegion. To ensure a valid index, the parameter "offset" should be between 0 and the number of pixels in the BufferedRegion (the latter can be found using ImageRegion::GetNumberOfPixels()).

Definition at line 331 of file itkImageBase.h.

virtual void itk::ImageBase< VImageDimension >::ComputeIndexToPhysicalPointMatrices ( ) [protected, virtual, inherited]

Compute helper matrices used to transform Index coordinates to PhysicalPoint coordinates and back. This method is virtual and will be overloaded in derived classes in order to provide backward compatibility behavior in classes that did not used to take image orientation into account.

OffsetValueType itk::ImageBase< VImageDimension >::ComputeOffset ( const IndexType & ind ) const [inline, inherited]

Compute an offset from the beginning of the buffer for a pixel at the specified index. The index is not checked as to whether it is inside the current buffer, so the computed offset could conceivably be outside the buffer. If bounds checking is needed, one can call ImageRegion::IsInside(ind) on the BufferedRegion prior to calling ComputeOffset.

Definition at line 295 of file itkImageBase.h.

void itk::ImageBase< VImageDimension >::ComputeOffsetTable ( ) [protected, inherited]

Calculate the offsets needed to move from one pixel to the next along a row, column, slice, volume, etc. These offsets are based on the size of the BufferedRegion. This should be called after the BufferedRegion is set.

virtual void itk::ImageBase< VImageDimension >::CopyInformation ( const DataObject * data ) [virtual, inherited]

Copy information from the specified data set. This method is part of the pipeline execution model. By default, a ProcessObject will copy meta-data from the first input to all of its outputs. See ProcessObject::GenerateOutputInformation(). Each subclass of DataObject is responsible for being able to copy whatever meta-data it needs from from another DataObject. ImageBase has more meta-data than its DataObject. Thus, it must provide its own version of CopyInformation() in order to copy the LargestPossibleRegion from the input parameter.

Reimplemented from itk::DataObject.

virtual LightObject::Pointer itk::Object::CreateAnother ( ) const [virtual, inherited]

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.

void itk::DataObject::DataHasBeenGenerated ( ) [inherited]

Inform the pipeline mechanism that data has been generated. This method is called by ProcessObject::UpdateOutputData() once the process object has finished generating its data. This essentially marks the DataObject as being updated and ready for use.

virtual void itk::Object::DebugOff ( ) const [virtual, inherited]

Turn debugging output off.

virtual void itk::Object::DebugOn ( ) const [virtual, inherited]

Turn debugging output on.

virtual void itk::LightObject::Delete ( ) [virtual, inherited]

Delete an itk object. This method should always be used to delete an object when the new operator was used to create it. Using the C delete method will not work with reference counting.

void itk::DataObject::DisconnectPipeline ( ) [inherited]

Separate this data object from the pipeline. This routine disconnects a data object from the upstream pipeline. Hence an Update() from downstream will not propagate back past this data object. To completely isolate this data object from the pipeline, the application must remove this data object from any filters which it is connected as the input.

template<class TLabelObject >

virtual LabelType itk::LabelMap< TLabelObject >::GetBackgroundValue ( ) const [virtual]

Set/Get the background label

virtual const RegionType& itk::ImageBase< VImageDimension >::GetBufferedRegion ( ) const [inline, virtual, inherited]

Get the region object that defines the size and starting index of the region of the image currently loaded in memory.

See also:: ImageRegion, SetLargestPossibleRegion(), SetRequestedRegion()

Definition at line 235 of file itkImageBase.h.

Command* itk::Object::GetCommand ( unsigned long tag ) [inherited]

Get the command associated with the given tag. NOTE: This returns a pointer to a Command, but it is safe to asign this to a Command::Pointer. Since Command inherits from LightObject, at this point in the code, only a pointer or a reference to the Command can be used.

bool itk::DataObject::GetDataReleased ( ) const [inline, inherited]

Get the flag indicating the data has been released.

Definition at line 334 of file itkDataObject.h.

bool itk::Object::GetDebug ( ) const [inherited]

Get the value of the debug flag.

virtual const DirectionType& itk::ImageBase< VImageDimension >::GetDirection ( void ) [virtual, inherited]

Get the direction cosines of the image. The direction cosines are vectors that point from one pixel to the next. For ImageBase and Image, the default direction is identity.

static bool itk::DataObject::GetGlobalReleaseDataFlag ( ) [static, inherited]

Turn on/off a flag to control whether every object releases its data after being used by a filter. Being a global flag, it controls the behavior of all DataObjects and ProcessObjects.

static bool itk::Object::GetGlobalWarningDisplay ( ) [static, inherited]

This is a global flag that controls whether any debug, warning or error messages are displayed.

static unsigned int itk::ImageBase< VImageDimension >::GetImageDimension ( ) [inline, static, inherited]

Image dimension. The dimension of an image is fixed at construction.

Definition at line 145 of file itkImageBase.h.

template<class TLabelObject >

LabelObjectType* itk::LabelMap< TLabelObject >::GetLabelObject ( const LabelType & label )

Return the LabelObject with the label given in parameter. This method thorws an exception if the label doesn't exist in this image, or if the label is the background one.

template<class TLabelObject >

const LabelObjectType* itk::LabelMap< TLabelObject >::GetLabelObject ( const LabelType & label ) const

template<class TLabelObject >

LabelObjectType* itk::LabelMap< TLabelObject >::GetLabelObject ( const IndexType & idx ) const

Return the label object at a given index. This method has a worst case complexity of O(L) where L is the number of lines in the image - use it with care.

template<class TLabelObject >

const LabelObjectContainerType& itk::LabelMap< TLabelObject >::GetLabelObjectContainer ( ) const

Return the label object container

template<class TLabelObject >

LabelObjectContainerType& itk::LabelMap< TLabelObject >::GetLabelObjectContainer ( )

Return the the label objects available in the label map

template<class TLabelObject >

LabelVectorType itk::LabelMap< TLabelObject >::GetLabels ( ) const

Return the labels of the label objects available in the label map

virtual const RegionType& itk::ImageBase< VImageDimension >::GetLargestPossibleRegion ( ) const [inline, virtual, inherited]

Get the region object that defines the size and starting index for the largest possible region this image could represent. This is used in determining how much memory would be needed to load an entire dataset. It is also used to determine boundary conditions.

See also:: ImageRegion, GetBufferedRegion(), GetRequestedRegion()

Definition at line 224 of file itkImageBase.h.

MetaDataDictionary& itk::Object::GetMetaDataDictionary ( void ) [inherited]

Returns:: A reference to this objects MetaDataDictionary.

Warning:: This reference may be changed.

const MetaDataDictionary& itk::Object::GetMetaDataDictionary ( void ) const [inherited]

Returns:: A constant reference to this objects MetaDataDictionary.

virtual unsigned long itk::Object::GetMTime ( ) const [virtual, inherited]

Return this objects modified time.

Referenced by itk::SpatialObject< ::itk::GetMeshDimension< TMesh >::PointDimension >::GetObjectMTime().

template<class TLabelObject >

virtual const char* itk::LabelMap< TLabelObject >::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::ImageBase< ::itk::GetImageDimension< TLabelObject >::ImageDimension >.

template<class TLabelObject >

LabelObjectType* itk::LabelMap< TLabelObject >::GetNthLabelObject ( const unsigned long & pos )

Return the LabelObject with at the position given in parameter. This method can be useful when the labels are not consecutives, but is quite inefficient. This method thorws an exception if the index doesn't exist in this image.

template<class TLabelObject >

const LabelObjectType* itk::LabelMap< TLabelObject >::GetNthLabelObject ( const unsigned long & pos ) const

virtual unsigned int itk::ImageBase< VImageDimension >::GetNumberOfComponentsPerPixel ( ) const [virtual, inherited]

INTERNAL This method is used internally by filters to copy meta-data from the output to the input. Users should not have a need to use this method.

Filters that override the ProcessObject's GenerateOutputInformation() should generally have the following line if they want to propagate meta- data for both Image and VectorImage

 outputImage->SetNumberOfComponentsPerPixel(
    inputImage->GetNumberOfComponentsPerPixel() )

See also:: ImageBase, VectorImage

Returns/Sets the number of components in the image. Note that for all images this is 1. Even for Image< RGBPixel< T >, 3 >. This is >= 1 only for time-series images such as itk::VectorImage.

template<class TLabelObject >

unsigned long itk::LabelMap< TLabelObject >::GetNumberOfLabelObjects ( ) const

Return the numbner of label objects in the image

const OffsetValueType* itk::ImageBase< VImageDimension >::GetOffsetTable ( ) const [inline, inherited]

Get the offset table. The offset table gives increments for moving from one pixel to next in the current row, column, slice, etc.. This table if of size [VImageDimension+1], because its values are computed progressively as: {1, N1, N1*N2, N1*N2*N3,...,(N1*...*Nn)} Where the values {N1,...,Nn} are the elements of the BufferedRegion::Size array. The last element of the OffsetTable is equivalent to the BufferSize. Having a [VImageDimension+1] size array, simplifies the implementation of some data accessing algorithms. The entries in the offset table are only valid after the BufferedRegion is set.

Definition at line 273 of file itkImageBase.h.

virtual const PointType& itk::ImageBase< VImageDimension >::GetOrigin ( void ) [virtual, inherited]

Get the origin of the image. The origin is the geometric coordinates of the index (0,0). The value returned is a pointer to a double array. For ImageBase and Image, the default origin is 0.

virtual const unsigned long& itk::DataObject::GetPipelineMTime ( ) [virtual, inherited]

The maximum MTime of all upstream filters and data objects. This does not include the MTime of this data object.

template<class TLabelObject >

const LabelType& itk::LabelMap< TLabelObject >::GetPixel ( const IndexType & idx ) const

Return the pixel value at a given index in the image. This method has a worst case complexity of O(L) where L is the number of lines in the image - use it with care.

virtual int itk::LightObject::GetReferenceCount ( ) const [inline, virtual, inherited]

Gets the reference count on this object.

Definition at line 106 of file itkLightObject.h.

virtual const bool& itk::DataObject::GetReleaseDataFlag ( ) [virtual, inherited]

Turn on/off a flag to control whether this object's data is released after being used by a filter.

virtual const RegionType& itk::ImageBase< VImageDimension >::GetRequestedRegion ( ) const [inline, virtual, inherited]

Get the region object that defines the size and starting index for the region of the image requested (i.e., the region of the image to be operated on by a filter).

See also:: ImageRegion, SetLargestPossibleRegion(), SetBufferedRegion()

Definition at line 260 of file itkImageBase.h.

SmartPointerForwardReference<ProcessObject> itk::DataObject::GetSource ( ) const [inherited]

Get the process object that generated this data object. If there is no process object, then the data object has been disconnected from the pipeline, or the data object was created manually. (Note: we cannot use the GetObjectMacro() defined in itkMacro because the mutual dependency of DataObject and ProcessObject causes compile problems. Also, a forward reference smart pointer is returned, not a smart pointer, because of the circular dependency between the process and data object.)

GetSource() returns a SmartPointerForwardReference and not a WeakPointer because it is assumed the code calling GetSource() wants to hold a long term reference to the source.

unsigned int itk::DataObject::GetSourceOutputIndex ( ) const [inherited]

Which of the source's outputs corresponds to this data object?

virtual const SpacingType& itk::ImageBase< VImageDimension >::GetSpacing ( void ) [virtual, inherited]

Get the spacing (size of a pixel) `of the image. The spacing is the geometric distance between image samples. The value returned is a pointer to a double array. For ImageBase and Image, the default data spacing is unity.

virtual unsigned long itk::DataObject::GetUpdateMTime ( ) const [virtual, inherited]

MTime for the last time this DataObject was generated.

static void itk::DataObject::GlobalReleaseDataFlagOff ( ) [inline, static, inherited]

Turn on/off a flag to control whether every object releases its data after being used by a filter. Being a global flag, it controls the behavior of all DataObjects and ProcessObjects.

template<class TLabelObject >

virtual void itk::LabelMap< TLabelObject >::Graft ( const DataObject * data ) [virtual]

Graft the data and information from one image to another. This is a convenience method to setup a second image with all the meta information of another image and use the same pixel container. Note that this method is different than just using two SmartPointers to the same image since separate DataObjects are still maintained. This method is similar to ImageSource::GraftOutput(). The implementation in ImageBase simply calls CopyInformation() and copies the region ivars. Subclasses of ImageBase are responsible for copying the pixel container.

Reimplemented from itk::ImageBase< ::itk::GetImageDimension< TLabelObject >::ImageDimension >.

template<class TLabelObject >

bool itk::LabelMap< TLabelObject >::HasLabel ( const LabelType label ) const

Return true is the image contains the label given in parameter and false otherwise. If the label is the background one, true is also returned, so this method may not be a good enough test before calling GetLabelObject().

virtual void itk::DataObject::PrepareForNewData ( ) [inline, virtual, inherited]

Setup a DataObject to receive new data. This method is called by the pipeline mechanism on each output of filter that needs to execute. The default implementation is to return a DataObject to its initial state. This may involve releasing previously allocated bulk data. Subclasses of DataObject may want to override this method and/or the Initialize() method if they want a different default behavior (for instance a DataObject might want finer control over its bulk data memory management).

virtual bool itk::ImageBase< VImageDimension >::RequestedRegionIsOutsideOfTheBufferedRegion ( ) [virtual, inherited]

Determine whether the RequestedRegion is outside of the BufferedRegion. This method returns true if the RequestedRegion is outside the BufferedRegion (true if at least one pixel is outside). This is used by the pipeline mechanism to determine whether a filter needs to re-execute in order to satisfy the current request. If the current RequestedRegion is already inside the BufferedRegion from the previous execution (and the current filter is up to date), then a given filter does not need to re-execute

Reimplemented from itk::DataObject.

virtual void itk::DataObject::ResetPipeline ( ) [virtual, inherited]

void itk::Object::SetDebug ( bool debugFlag ) const [inherited]

Set the value of the debug flag. A non-zero value turns debugging on.

virtual void itk::ImageBase< VImageDimension >::SetDirection ( const DirectionType direction ) [virtual, inherited]

Set the direction cosines of the image. The direction cosines are vectors that point from one pixel to the next.

One row of the matrix indicates the direction cosines of the unit vector that is parallel to the lines of the image grid corresponding to that dimension. For example, and image with Direction matrix

0.866 0.500 -0.500 0.866

has an image grid were the fastest changing index (dimension[0]) walks over a line that in Physical space is oriented parallel to the vector (0.866,0.5). The second fastest changing index (dimension[1]) walks along a line that in Physical space is oriented parallel to the vector (-0.5,0.866)

The vectors whose direction cosines are stored in the Direction matrix, are expected to be orthogonal to each other, and they are expected to form a right handed coordinate system, but this is not checked nor enforced in the itk::ImageBase.

If a label object already exist with that label, the line is added to it WITHOUT any check - it means that if the label object may contain several time the same pixel after have run that method. This method runs in constant time.

void itk::Object::SetMetaDataDictionary ( const MetaDataDictionary & rhs ) [inherited]

Returns:: Set the MetaDataDictionary

virtual void itk::ImageBase< VImageDimension >::SetNumberOfComponentsPerPixel ( unsigned int ) [virtual, inherited]

INTERNAL This method is used internally by filters to copy meta-data from the output to the input. Users should not have a need to use this method.

Filters that override the ProcessObject's GenerateOutputInformation() should generally have the following line if they want to propagate meta- data for both Image and VectorImage

 outputImage->SetNumberOfComponentsPerPixel(
    inputImage->GetNumberOfComponentsPerPixel() )

See also:: ImageBase, VectorImage

Returns/Sets the number of components in the image. Note that for all images this is 1. Even for Image< RGBPixel< T >, 3 >. This is >= 1 only for time-series images such as itk::VectorImage.

template<class TLabelObject >

void itk::LabelMap< TLabelObject >::SetPixel	(	const IndexType &	idx,
		const LabelType &	label
	)

Set the pixel value at a given index in the image. If no label object has this pixel value, a new label object is created. If a label object already exist, the index is added to it. The worst case complexity of this method is O(L) where L is the number of lines in the image. However, the execution time will be quite low if the pixels are set in the image in raster mode.

virtual void itk::ImageBase< VImageDimension >::SetRequestedRegion ( const RegionType & region ) [virtual, inherited]

Set the region object that defines the size and starting index for the region of the image requested (i.e., the region of the image to be operated on by a filter). Setting the RequestedRegion does not cause the object to be modified. This method is called internally by the pipeline and therefore bypasses the modified time calculation.

See also:: ImageRegion, SetLargestPossibleRegion(), SetBufferedRegion()

virtual void itk::ImageBase< VImageDimension >::SetRequestedRegion ( DataObject * data ) [virtual, inherited]

Set the requested region from this data object to match the requested region of the data object passed in as a parameter. This method implements the API from DataObject. The data object parameter must be castable to an ImageBase. Setting the RequestedRegion does not cause the object to be modified. This method is called internally by the pipeline and therefore bypasses the modified time calculation.

Reimplemented from itk::DataObject.

virtual void itk::ImageBase< VImageDimension >::SetRequestedRegionToLargestPossibleRegion ( ) [virtual, inherited]

Set the RequestedRegion to the LargestPossibleRegion. This forces a filter to produce all of the output in one execution (i.e. not streaming) on the next call to Update().

Reimplemented from itk::DataObject.

virtual void itk::ImageBase< VImageDimension >::SetSpacing ( const SpacingType & spacing ) [virtual, inherited]

Set the spacing (size of a pixel) of the image. The spacing is the geometric distance between image samples. It is stored internally as double, but may be set from float. These methods also pre-compute the Index to Physical point transforms of the image.

See also:: GetSpacing()

virtual void itk::ImageBase< VImageDimension >::SetSpacing ( const float spacing[VImageDimension] ) [virtual, inherited]

Compute the index of the pixel at a specified offset from the beginning of the buffered region. Bounds checking is not performed. Thus, the computed index could be outside the BufferedRegion. To ensure a valid index, the parameter "offset" should be between 0 and the number of pixels in the BufferedRegion (the latter can be found using ImageRegion::GetNumberOfPixels()).

virtual void itk::ImageBase< VImageDimension >::SetSpacing ( const double spacing[VImageDimension] ) [virtual, inherited]

Compute the index of the pixel at a specified offset from the beginning of the buffered region. Bounds checking is not performed. Thus, the computed index could be outside the BufferedRegion. To ensure a valid index, the parameter "offset" should be between 0 and the number of pixels in the BufferedRegion (the latter can be found using ImageRegion::GetNumberOfPixels()).

bool itk::DataObject::ShouldIReleaseData ( ) const [inherited]

Return flag indicating whether data should be released after use by a filter.

See also:: Transform Take a vector or covariant vector that has been computed in the coordinate system parallel to the image grid and rotate it by the direction cosines in order to get it in terms of the coordinate system of the image acquisition device. This implementation in the OrientedImage multiply the array (vector or covariant vector) by the matrix of Direction Cosines. The arguments of the method are of type FixedArray to make possible to use this method with both Vector and CovariantVector. The Method is implemented differently in the itk::Image.; Image

virtual void itk::Object::UnRegister ( ) const [virtual, inherited]

Decrease the reference count (release by another object).

Reimplemented from itk::LightObject.

virtual void itk::DataObject::Update ( ) [virtual, inherited]

Provides opportunity for the data object to insure internal consistency before access. Also causes owning source/filter (if any) to update itself. The Update() method is composed of UpdateOutputInformation(), PropagateRequestedRegion(), and UpdateOutputData(). This method may call methods that throw an InvalidRequestedRegionError exception. This exception will leave the pipeline in an inconsistent state. You will need to call ResetPipeline() on the last ProcessObject in your pipeline in order to restore the pipeline to a state where you can call Update() again.

virtual void itk::ImageBase< VImageDimension >::UpdateOutputData ( ) [virtual, inherited]

Overriden from base class to check if the requested image region has zero pixels.

This is needed so that filters can set an input's requested region to zero, to indicate that it does not need to be updated or executed.

Reimplemented from itk::DataObject.

virtual void itk::ImageBase< VImageDimension >::UpdateOutputInformation ( ) [virtual, inherited]

Update the information for this DataObject so that it can be used as an output of a ProcessObject. This method is used the pipeline mechanism to propagate information and initialize the meta data associated with a DataObject. This method calls its source's ProcessObject::UpdateOutputInformation() which determines modified times, LargestPossibleRegions, and any extra meta data like spacing, origin, etc.

Reimplemented from itk::DataObject.

virtual bool itk::ImageBase< VImageDimension >::VerifyRequestedRegion ( ) [virtual, inherited]

Verify that the RequestedRegion is within the LargestPossibleRegion. If the RequestedRegion is not within the LargestPossibleRegion, then the filter cannot possible satisfy the request. This method returns true if the request can be satisfied and returns fails if the request cannot. This method is used by PropagateRequestedRegion(). PropagateRequestedRegion() throws a InvalidRequestedRegionError exception is the requested region is not within the LargestPossibleRegion.
