Detailed Description

template<class TScalarType>
class itk::watershed::SegmentTable< TScalarType >

A table for storing segmentation information in various component filters of the watershed segmentation algorithm. See itk::WatershedImageFilter for an overview.

: This is a hash table that holds information about labeled segments in an image. Keys in the table are label values (unsigned long). Each entry in the table records the minimum value in the segment region and a list of all the adjacent segments in the image. The adjacency (edge) list also holds a saliency value (likelihood of merge) for each adjacency.

bool itk::watershed::SegmentTable< TScalarType >::Add	(	unsigned long	a,
		const segment_t &	t
	)

Inserts a segment into the table

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 TScalarType >

Iterator itk::watershed::SegmentTable< TScalarType >::Begin ( ) [inline]

Merges two entries of the table. from->to Returns an iterator pointing to the first element in the (unordered) table.

Definition at line 172 of file itkWatershedSegmentTable.h.

template<class TScalarType >

ConstIterator itk::watershed::SegmentTable< TScalarType >::Begin ( ) const [inline]

Returns a const iterator pointing to the first element in the (unordered) table.

Definition at line 180 of file itkWatershedSegmentTable.h.

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

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

template<class TScalarType >

void itk::watershed::SegmentTable< TScalarType >::Clear ( ) [inline]

Removes all the entries in the table.

Definition at line 151 of file itkWatershedSegmentTable.h.

template<class TScalarType >

void itk::watershed::SegmentTable< TScalarType >::Copy ( const Self & o ) [inline]

Copies the contents of another segment table into this segment table. This is really operator= in disguise, although superclass information is not copied.

Definition at line 208 of file itkWatershedSegmentTable.h.

References itk::watershed::SegmentTable< TScalarType >::m_HashMap, and itk::watershed::SegmentTable< TScalarType >::m_MaximumDepth.

virtual void itk::DataObject::CopyInformation ( const DataObject * ) [inline, 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. The default implementation of this method is empty. If a subclass overrides this method, it should always call its superclass' version.

Definition at line 439 of file itkDataObject.h.

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 TScalarType >

bool itk::watershed::SegmentTable< TScalarType >::Empty ( ) const [inline]

Returns true if the table is empty and false if the table is not empty.

Definition at line 156 of file itkWatershedSegmentTable.h.

template<class TScalarType >

ConstIterator itk::watershed::SegmentTable< TScalarType >::End ( ) const [inline]

Returns a const iterator pointing to one element past the last element in the (unordered table).

Definition at line 184 of file itkWatershedSegmentTable.h.

template<class TScalarType >

Iterator itk::watershed::SegmentTable< TScalarType >::End ( ) [inline]

Returns an iterator pointing to one element past the last element in the (unordered table).

Definition at line 176 of file itkWatershedSegmentTable.h.

template<class TScalarType >

void itk::watershed::SegmentTable< TScalarType >::Erase ( const unsigned long a ) [inline]

Deletes an entry from the table.

Definition at line 147 of file itkWatershedSegmentTable.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.

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.

template<class TScalarType >

ScalarType itk::watershed::SegmentTable< TScalarType >::GetMaximumDepth ( ) const [inline]

Set/Get the maximum depth of image on which this segment table is based. (Should set really be calling modified? jc 11/16/01)

Definition at line 201 of file itkWatershedSegmentTable.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.

virtual const char* itk::watershed::SegmentTable< TScalarType >::GetNameOfClass ( ) const [virtual]

Define smart pointers for this object

Reimplemented from itk::DataObject.

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.

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.

template<class TScalarType >

unsigned int itk::watershed::SegmentTable< TScalarType >::GetSegmentMemorySize ( ) const [inline]

Convenience methods for debugging

Definition at line 187 of file itkWatershedSegmentTable.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 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.

Definition at line 319 of file itkDataObject.h.

static void itk::DataObject::GlobalReleaseDataFlagOn ( ) [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.

Definition at line 317 of file itkDataObject.h.

static void itk::Object::GlobalWarningDisplayOff ( ) [inline, static, inherited]

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

References itk::Object::SetGlobalWarningDisplay().

virtual void itk::DataObject::Graft ( const DataObject * ) [inline, virtual, inherited]

Method for grafting the content of one data object into another one. This method is intended to be overloaded by derived classes. Each one of them should use dynamic_casting in order to verify that the grafted object is actually of the same type as the class on which the Graft() method was invoked.

Definition at line 453 of file itkDataObject.h.

bool itk::Object::HasObserver ( const EventObject & event ) const [inherited]

Return true if an observer is registered for this event.

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

Restore the data object to its initial state. This means releasing memory.

Definition at line 119 of file itkWatershedSegmentTable.h.

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

Update the modification time for this object. Many filters rely on the modification time to determine if they need to recompute their data.

static Pointer itk::watershed::SegmentTable< TScalarType >::New ( ) [static]

Define smart pointers for this object

Reimplemented from itk::Object.

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).

Definition at line 389 of file itkDataObject.h.

void itk::LightObject::Print	(	std::ostream &	os,
		Indent	indent = `0`
	)			const `[inherited]`

virtual void itk::LightObject::PrintHeader	(	std::ostream &	os,
		Indent	indent
	)			const `[protected, virtual, inherited]`

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.

bool itk::Object::PrintObservers	(	std::ostream &	os,
		Indent	indent
	)			const `[protected, inherited]`

void itk::DataObject::PrintSelf	(	std::ostream &	os,
		Indent	indent
	)			const `[protected, virtual, inherited]`

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::Object.

virtual void itk::LightObject::PrintTrailer	(	std::ostream &	os,
		Indent	indent
	)			const `[protected, virtual, inherited]`

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.

template<class TScalarType >

void itk::watershed::SegmentTable< TScalarType >::PruneEdgeLists ( ScalarType maximum_saliency )

Iterates through the table and removes edges in every edge list whose saliencies are above the specified maximum. Requires that the edge lists have been sorted prior to calling this method.

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

Increase the reference count (mark as used by another object).

Reimplemented from itk::LightObject.

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

Release data back to system to conserve memory resource. Used during pipeline execution. Releasing this data does not make down-stream data invalid, so it does not modify the MTime of this data object.

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

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

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

Remove all observers .

void itk::Object::RemoveObserver ( unsigned long tag ) [inherited]

Remove the observer with this tag value.

virtual bool itk::DataObject::RequestedRegionIsOutsideOfTheBufferedRegion ( ) [inline, 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 in itk::ImageBase< VImageDimension >, itk::PointSet< TPixelType, VDimension, TMeshTraits >, itk::QuadEdgeMesh< TPixel, VDimension, TTraits >, itk::SpatialObject< TDimension >, itk::ImageBase< ::itk::GetImageDimension< TLabelObject >::ImageDimension >, itk::ImageBase< ::itk::GetImageDimension< VectorImage< TPixelType, Dimension > >::ImageDimension >, itk::ImageBase< ::itk::GetImageDimension< TImage >::ImageDimension >, itk::PointSet< TPixel, VDimension, TTraits >, itk::PointSet< TCoordType, VDimension, DefaultDynamicMeshTraits< TCoordType, 2, 2, TCoordType > >, itk::SpatialObject< 3 >, and itk::SpatialObject< ::itk::GetMeshDimension< TMesh >::PointDimension >.

Definition at line 413 of file itkDataObject.h.

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

Methods to update the pipeline. Called internally by the pipeline mechanism.

virtual void itk::DataObject::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 in the pipeline mechanism to propagate information and initialize the meta data associated with a DataObject. Any implementation of this method in a derived class is assumed to call its source's ProcessObject::UpdateOutputInformation() which determines modified times, LargestPossibleRegions, and any extra meta data like spacing, origin, etc. Default implementation simply call's it's source's UpdateOutputInformation().

virtual bool itk::DataObject::VerifyRequestedRegion ( ) [inline, virtual, inherited]

Verify that the RequestedRegion is within the LargestPossibleRegion.

If the RequestedRegion is not within the LargestPossibleRegion, then the filter cannot possibly satisfy the request. This method returns true if the request can be satisfied (even if it will be necessary to process the entire LargestPossibleRegion) and returns false otherwise. This method is used by PropagateRequestedRegion(). PropagateRequestedRegion() throws a InvalidRequestedRegionError exception if the requested region is not within the LargestPossibleRegion. Default implementation simply returns true in order to support DataObjects that do not need regions (for instance itk::EquivalencyTable).
