Detailed Description

template<unsigned int VDimension>
class itk::FourierSeriesPath< VDimension >

Represent a closed path through ND Space by its frequency components.

This class is intended to represent closed parametric paths through an image which are defined by their Fourier coeficients (frequency components). The paths must be closed and defined over the interval [0,1], where the paths' values at input 0 and input 1 are identical. The user can control how many harmonics (how high of frequency components) are represented by a given instantiation of this class. Classic applications of this class include smoothing other closed paths (by finding and using only the first n harmonics of their frequency components) and interpolating exact derivatives of other closed paths by first converting the other paths to FourierSeriesPaths, which have an exactly defined algebraic derivative. (As many harmonics as are necessary to adequately approximate the original path should be used when approximating derivatives.)

Member Function Documentation

template<unsigned int VDimension>

void itk::FourierSeriesPath< VDimension >::AddHarmonic	(	const VectorType &	CosCoefficients,
		const VectorType &	SinCoefficients
	)

Add another harmonic's frequency coefficients.

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

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

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

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

template<unsigned int VDimension>

void itk::FourierSeriesPath< VDimension >::Clear ( ) [inline]

Clear all frequency coefficients (including the "DC" coefficients).

Definition at line 102 of file itkFourierSeriesPath.h.

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 TInput, class TOutput, unsigned int VDimension>

virtual InputType itk::Path< TInput, TOutput, VDimension >::EndOfInput ( ) const [inline, virtual, inherited]

Where does the path end (what is the last valid input value)? This value is sometimes used by IncrementInput() to go to the end of a path.

Reimplemented in itk::ChainCodePath< VDimension >, itk::OrthogonallyCorrected2DParametricPath, itk::PolyLineParametricPath< VDimension >, and itk::ChainCodePath< 2 >.

Definition at line 86 of file itkPath.h.

template<class TInput, class TOutput, unsigned int VDimension>

virtual OutputType itk::Path< TInput, TOutput, VDimension >::Evaluate ( const InputType & input ) const [pure virtual, inherited]

Evaluate the path at specified location along the path. Return data is the path's "natural" format.

template<unsigned int VDimension>

virtual OutputType itk::FourierSeriesPath< VDimension >::Evaluate ( const InputType & input ) const [virtual]

Return the location of the parametric path at the specified location.

template<unsigned int VDimension>

virtual VectorType itk::FourierSeriesPath< VDimension >::EvaluateDerivative ( const InputType & input ) const [virtual]

Evaluate the first derivative of the ND output with respect to the 1D input. This is an exact, algebraic function.

Reimplemented from itk::ParametricPath< VDimension >.

template<class TInput, class TOutput, unsigned int VDimension>

virtual IndexType itk::Path< TInput, TOutput, VDimension >::EvaluateToIndex ( const InputType & input ) const [pure virtual, inherited]

Like Evaluate(), except always returns an index

template<unsigned int VDimension>

virtual IndexType itk::ParametricPath< VDimension >::EvaluateToIndex ( const InputType & input ) const [virtual, inherited]

Return the nearest index to the parametric path at the specified location. This is a wrapper to Evaluate().

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.

template<unsigned int VDimension>

virtual const InputType& itk::ParametricPath< VDimension >::GetDefaultInputStepSize ( ) [virtual, inherited]

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

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

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

Returns:: A constant reference to this objects MetaDataDictionary.

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

Returns:: A reference to this objects MetaDataDictionary.

Warning:: This reference may be changed.

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

Return this objects modified time.

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

template<unsigned int VDimension>

virtual const char* itk::FourierSeriesPath< VDimension >::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::ParametricPath< VDimension >.

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

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]

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.

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.

template<class TInput, class TOutput, unsigned int VDimension>

virtual OffsetType itk::Path< TInput, TOutput, VDimension >::IncrementInput ( InputType & input ) const [pure virtual, inherited]

Increment the input variable passed by reference such that the ND index of the path moves to its next vertex-connected (8-connected in 2D) neighbor. Return the Index-space offset of the path from its prior input to its new input. If the path is unable to increment, input is not changed and an offset of Zero is returned. Children are not required to implement general bounds checking, but are required to return an offset of zero when trying to increment from the final valid input value.

template<unsigned int VDimension>

virtual OffsetType itk::ParametricPath< VDimension >::IncrementInput ( InputType & input ) const [virtual, inherited]

Increment the input variable passed by reference such that the ND index of the path moves to its next vertex-connected (8-connected in 2D) neighbor. Return the Index-space offset of the path from its prior input to its new input. If the path is unable to increment, input is not changed and an offset of Zero is returned. Children are not required to implement bounds checking.

This is a fairly slow, iterative algorithm that numerically converges to the next index along the path, in a vertex-connected (8-connected in 2D) fashion. When possible, children of this class should overload this function with something more efficient.

WARNING: This default implementation REQUIRES that the ND endpoint of the path be either unique or coincident only with the startpoint, since it uses the endpoint as a stopping condition.

virtual void itk::FourierSeriesPath< VDimension >::Initialize ( void ) [inline, virtual]

itk::Path< TInput, TOutput, VDimension >::itkStaticConstMacro	(	PathDimension	,
		unsigned	int,
		VDimension
	)			`[inherited]`

Path dimension. The dimension of a path is fixed at construction.

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.

template<unsigned int VDimension>

static Pointer itk::FourierSeriesPath< VDimension >::New ( ) [static]

New() method for dynamic construction

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]`

Cause the object to print itself out.

Referenced by itk::WeakPointer< itk::ProcessObject >::Print(), and itk::SmartPointer< itk::MutualInformationImageToImageMetric >::Print().

virtual void itk::LightObject::PrintHeader	(	std::ostream &	os,

template<unsigned int VDimension>

void itk::FourierSeriesPath< VDimension >::PrintSelf	(	std::ostream &	os,
		Indent	indent
	)			const `[protected, virtual]`

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::ParametricPath< VDimension >.

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

virtual void itk::DataObject::PropagateRequestedRegion ( ) throw (InvalidRequestedRegionError) [virtual, inherited]

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

virtual void itk::DataObject::PropagateResetPipeline ( ) [protected, virtual, inherited]

Propagate a call to ResetPipeline(). Called only from ProcessObject.

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]

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

void itk::Object::RemoveAllObservers ( ) [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< itk::VectorImage< TPixelType, Dimension > >::ImageDimension >, itk::ImageBase< ::itk::GetImageDimension< TImage >::ImageDimension >, itk::PointSet< TCoordType, VDimension, itk::DefaultDynamicMeshTraits< TCoordType, 2, 2, TCoordType > >, itk::PointSet< TPixel, VDimension, TTraits >, 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]

Reset the pipeline. If an exception is thrown during an Update(), the pipeline may be in an inconsistent state. This method clears the internal state of the pipeline so Update() can be called.

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

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

template<unsigned int VDimension>

virtual void itk::ParametricPath< VDimension >::SetDefaultInputStepSize ( InputType _arg ) [virtual, inherited]

static void itk::DataObject::SetGlobalReleaseDataFlag ( bool val ) [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 void itk::Object::SetGlobalWarningDisplay ( bool flag ) [static, inherited]

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

Referenced by itk::Object::GlobalWarningDisplayOff(), and itk::Object::GlobalWarningDisplayOn().

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

Returns:: Set the MetaDataDictionary

void itk::DataObject::SetPipelineMTime ( unsigned long time ) [inline, inherited]

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

Definition at line 373 of file itkDataObject.h.

virtual void itk::Object::SetReferenceCount ( int ) [virtual, inherited]

Sets the reference count (use with care)

Reimplemented from itk::LightObject.

void itk::DataObject::SetReleaseDataFlag ( bool flag ) [inline, inherited]

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

Definition at line 304 of file itkDataObject.h.

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

Set the requested region from this data object to match the requested region of the data object passed in as a parameter. For DataObject's that do not support Regions, this method does nothing. Subclasses of DataObject that do support Regions, provide an alternative implementation.

Definition at line 446 of file itkDataObject.h.

virtual void itk::DataObject::SetRequestedRegionToLargestPossibleRegion ( ) [inline, 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().

Definition at line 402 of file itkDataObject.h.

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

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

template<class TInput, class TOutput, unsigned int VDimension>

virtual InputType itk::Path< TInput, TOutput, VDimension >::StartOfInput ( ) const [inline, virtual, inherited]

Where does the path begin? For most types of paths, the path will begin at zero. This value can be overridden in children, and is necessary for iterators to know how to go to the beginning of a path.

Reimplemented in itk::OrthogonallyCorrected2DParametricPath.

Definition at line 79 of file itkPath.h.

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

Decrease the reference count (release by another object).

Reimplemented from itk::LightObject.

Referenced by itk::SmartPointer< itk::MutualInformationImageToImageMetric >::operator=().

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).

InputType itk::ParametricPath< VDimension >::m_DefaultInputStepSize [protected, inherited]

Default 1D input increment amount to trace along the path. Also, the value used by the defualt implementation of EvaluateDerivative() for numerically approximating the derivative with the change over a single default-sized step. (NOTE that the default implementation of EvaluateDerivative() should never be used in practice, but users or lazzy developers may nevertheless unwisely choose to do so anyway.) For integer- input-types, 1 is probably the correct value. For double-input-types, either 1 or 0.1 are probably good values. This value should be set in the constructor of all instantiable children. Values set in child constructors overwrite values set in parent constructors.
