Detailed Description

template<class TPixel, unsigned int VImageDimension = 3>
class itk::VectorImage< TPixel, VImageDimension >

Templated n-dimensional vector image class.

This class differs from Image in that it is intended to represent multiple images. Each pixel represents k measurements, each of datatype TPixel. The memory organization of the resulting image is as follows: ... Pi0 Pi1 Pi2 Pi3 P(i+1)0 P(i+1)1 P(i+1)2 P(i+1)3 P(i+2)0 ... where Pi0 represents the 0th measurement of the pixel at index i.

Conceptually, a VectorImage< double, 3 > is the same as a Image< VariableLengthVector< double >, 3 >. The difference lies in the memory organization. The latter results in a fragmented organization with each location in the Image holding a pointer to an VariableLengthVector holding the actual pixel. The former stores the k pixels instead of a pointer reference, which apart from avoiding fragmentation of memory also avoids storing a 8 bytes of pointer reference for each pixel. The parameter k can be set using SetVectorLength.

The API of the class is such that it returns a pixeltype VariableLengthVector< double > when queried, with the data internally pointing to the buffer. (the container does not manage the memory). Similarly SetPixel calls can be made with VariableLengthVector< double >.

The API of this class is similar to Image.

Caveats:: When using Iterators on this image, you cannot use the it.Value(). You must use Set/Get() methods instead.

Note:: This work is part of the National Alliance for Medical Image Computing (NAMIC), funded by the National Institutes of Health through the NIH Roadmap for Medical Research, Grant U54 EB005149.

Member Function Documentation

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 TPixel, unsigned int VImageDimension = 3>

void itk::VectorImage< TPixel, VImageDimension >::Allocate ( ) [virtual]

Allocate the image memory. The size of the image must already be set, e.g. by calling SetRegions().

Reimplemented from itk::ImageBase< VImageDimension >.

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 VImageDimension = 2>

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.

template<unsigned int VImageDimension = 2>

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.

Reimplemented in itk::Image< TPixel, VImageDimension >, itk::OrientedImage< TPixel, VImageDimension >, itk::Image< BloxCoreAtomPixel< NDimension >, TImageDimension >, itk::Image< TNode *, VImageDimension >, itk::Image< BloxBoundaryProfilePixel< TImageDimension >, TImageDimension >, itk::Image< TBloxPixelType, TImageDimension >, and itk::Image< BloxBoundaryPointPixel< TImageDimension >, TImageDimension >.

template<unsigned int VImageDimension = 2>

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.

template<unsigned int VImageDimension = 2>

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.

template<unsigned int VImageDimension = 2>

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 TPixel, unsigned int VImageDimension = 3>

void itk::VectorImage< TPixel, VImageDimension >::FillBuffer ( const PixelType & value )

Fill the image buffer with a value. Be sure to call Allocate() first.

template<unsigned int VImageDimension = 2>

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.

template<class TPixel, unsigned int VImageDimension = 3>

InternalPixelType* itk::VectorImage< TPixel, VImageDimension >::GetBufferPointer ( ) [inline]

Return a pointer to the beginning of the buffer. This is used by the image iterator class.

Definition at line 253 of file itkVectorImage.h.

template<class TPixel, unsigned int VImageDimension = 3>

const InternalPixelType* itk::VectorImage< TPixel, VImageDimension >::GetBufferPointer ( ) const [inline]

Return a pointer to the beginning of the buffer. This is used by the image iterator class.

Definition at line 255 of file itkVectorImage.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.

template<unsigned int VImageDimension = 2>

virtual const DirectionType& itk::ImageBase< VImageDimension >::GetDirection ( ) [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.

template<unsigned int VImageDimension = 2>

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<unsigned int VImageDimension = 2>

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()

Referenced by itk::fem::FEMRegistrationFilter< TMovingImage, TFixedImage >::SetDeformationField().

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.

template<class TPixel, unsigned int VImageDimension = 3>

virtual const char* itk::VectorImage< TPixel, VImageDimension >::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::ImageBase< VImageDimension >.

template<class TPixel, unsigned int VImageDimension = 3>

NeighborhoodAccessorFunctorType itk::VectorImage< TPixel, VImageDimension >::GetNeighborhoodAccessor ( ) [inline]

template<class TPixel, unsigned int VImageDimension = 3>

const NeighborhoodAccessorFunctorType itk::VectorImage< TPixel, VImageDimension >::GetNeighborhoodAccessor ( ) const [inline]

Return the NeighborhoodAccessor functor

Definition at line 296 of file itkVectorImage.h.

template<class TPixel, unsigned int VImageDimension = 3>

virtual unsigned int itk::VectorImage< TPixel, VImageDimension >::GetNumberOfComponentsPerPixel ( ) const [virtual]

Get/Set the number of components each pixel has, ie the VectorLength

Reimplemented from itk::ImageBase< VImageDimension >.

template<unsigned int VImageDimension = 2>

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.

template<unsigned int VImageDimension = 2>

virtual const PointType& itk::ImageBase< VImageDimension >::GetOrigin ( ) [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 TPixel, unsigned int VImageDimension = 3>

PixelType itk::VectorImage< TPixel, VImageDimension >::GetPixel ( const IndexType & index ) [inline]

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.

virtual void itk::VectorImage< TPixel, VImageDimension >::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. The implementation here refers to the superclass' implementation and then copies over the pixel container.

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::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.
