Detailed Description

template<unsigned int VImageDimension = 2>
class itk::ImageBase< VImageDimension >

Base class for templated image classes.

ImageBase is the base class for the templated Image classes. ImageBase is templated over the dimension of the image. It provides the API and ivars that depend solely on the dimension of the image. ImageBase does not store any of the image (pixel) data. Storage for the pixels and the pixel access methods are defined in subclasses of ImageBase, namely Image and ImageAdaptor.

ImageBase manages the geometry of an image. The geometry of an image is defined by its position, orientation, spacing, and extent.

The position and orientation of an image is defined by its "Origin" and its "Directions". The "Origin" is the physical position of the pixel whose "Index" is all zeros. The "Direction" of an image is a matrix whose columns indicate the direction in physical space that each dimension of the image traverses. The first column defines the direction that the fastest moving index in the image traverses in physical space while the last column defines the direction that the slowest moving index in the image traverses in physical space.

The extent of an image is defined by the pixel spacing and a set of regions. The "Spacing" is the size of a pixel in physical space along each dimension. Regions describe a portion of an image grid via a starting index for the image array and a size (or number of pixels) in each dimension. The ivar LargestPossibleRegion defines the size and starting index of the image dataset. The entire image dataset, however, may not be resident in memory. The region of the image that is resident in memory is defined by the "BufferedRegion". The Buffer is a contiguous block of memory. The third set of meta-data defines a region of interest, called the "RequestedRegion". The RequestedRegion is used by the pipeline execution model to define what a filter is requested to produce.

[RegionIndex, RegionSize] C [BufferIndex, BufferSize] C [ImageIndex, ImageSize]

ImageBase provides all the methods for converting between the physical space and index coordinate frames. TransformIndexToPhysicalPoint() converts an Index in the pixel array into its coordinates in physical space. TransformPhysicalPointToIndex() converts a position in physical space into an Index into the pixel array (using rounding). Subpixel locations are supported by methods that convert to and from ContinuousIndex types.

ImageBase also provides helper routines for the ImageIterators which convert an Index to an offset in memory from the first pixel address as well as convert an offset in memory from the first pixel address to an Index.

Examples: SphinxExamples/src/Core/Common/CreateAnotherInstanceOfAnImage/Code.cxx.

Member Function Documentation

◆ Allocate()

template<unsigned int VImageDimension = 2>

virtual void itk::ImageBase< VImageDimension >::Allocate ( bool initialize = false )

virtual

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

This method should be pure virtual, if backwards compatibility was not required.

◆ AllocateInitialized()

template<unsigned int VImageDimension = 2>

void itk::ImageBase< VImageDimension >::AllocateInitialized ( )

inline

Allocates the pixel buffer of the image, zero-initializing its pixels. AllocateInitialized() is equivalent to Allocate(true). It is just intended to make the code more readable.

Definition at line 258 of file itkImageBase.h.

◆ ComputeIndex()

template<unsigned int VImageDimension = 2>

IndexType itk::ImageBase< VImageDimension >::ComputeIndex ( OffsetValueType offset ) const

inline

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 408 of file itkImageBase.h.

◆ ComputeIndexToPhysicalPointMatrices()

template<unsigned int VImageDimension = 2>

virtual void itk::ImageBase< VImageDimension >::ComputeIndexToPhysicalPointMatrices ( )

protectedvirtual

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 >, and itk::Image< TNode *, VImageDimension >.

◆ ComputeOffset()

template<unsigned int VImageDimension = 2>

OffsetValueType itk::ImageBase< VImageDimension >::ComputeOffset ( const IndexType & ind ) const

inline

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 374 of file itkImageBase.h.

◆ ComputeOffsetTable()

template<unsigned int VImageDimension = 2>

void itk::ImageBase< VImageDimension >::ComputeOffsetTable ( )

protected

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.

◆ CopyInformation()

template<unsigned int VImageDimension = 2>

void itk::ImageBase< VImageDimension >::CopyInformation ( const DataObject * data )

overridevirtual

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.

Referenced by itk::ImageToImageFilterDetail::ImageToImageFilterDefaultCopyInformation().

◆ FastComputeIndex()

template<unsigned int VImageDimension = 2>

IndexType itk::ImageBase< VImageDimension >::FastComputeIndex ( OffsetValueType offset ) const

inlineprotected

Directly computes 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()).

Warning: unlike ComputeOffset(), this version does not incur a virtual call. It's meant to be used only for itk::Image<>, itk::VectorImage<> and itk::SpecialCoordinatesImage<>.

Definition at line 918 of file itkImageBase.h.

◆ FastComputeOffset()

template<unsigned int VImageDimension = 2>

OffsetValueType itk::ImageBase< VImageDimension >::FastComputeOffset ( const IndexType & ind ) const

inlineprotected

Directly computes 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.

Warning: unlike ComputeOffset(), this version does not incur a virtual call. It's meant to be used only for itk::Image<>, itk::VectorImage<> and itk::SpecialCoordinatesImage<>.

Definition at line 897 of file itkImageBase.h.

◆ GetBufferedRegion()

template<unsigned int VImageDimension = 2>

virtual const RegionType& itk::ImageBase< VImageDimension >::GetBufferedRegion ( ) const

inlinevirtual

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 294 of file itkImageBase.h.

◆ GetDirection()

template<unsigned int VImageDimension = 2>

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

virtual

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.

Referenced by itk::ImageToImageFilterDetail::ImageToImageFilterDefaultCopyInformation().

◆ GetImageDimension()

template<unsigned int VImageDimension = 2>

static unsigned int itk::ImageBase< VImageDimension >::GetImageDimension ( )

inlinestatic

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

Definition at line 179 of file itkImageBase.h.

◆ GetInverseDirection()

template<unsigned int VImageDimension = 2>

virtual const DirectionType& itk::ImageBase< VImageDimension >::GetInverseDirection ( ) const

virtual

Get the inverse direction cosines of the image. These are calculated automatically in SetDirection, thus there is no Set accessor.

◆ GetLargestPossibleRegion()

template<unsigned int VImageDimension = 2>

virtual const RegionType& itk::ImageBase< VImageDimension >::GetLargestPossibleRegion ( ) const

inlinevirtual

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 true conditions.

◆ GetNameOfClass()

template<unsigned int VImageDimension = 2>

const char* itk::ImageBase< VImageDimension >::GetNameOfClass ( ) const

overridevirtual

See also: LightObject::GetNameOfClass()

Reimplemented from itk::DataObject.

◆ GetNumberOfComponentsPerPixel()

template<unsigned int VImageDimension = 2>

virtual unsigned int itk::ImageBase< VImageDimension >::GetNumberOfComponentsPerPixel ( ) const

virtual

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 in the ImageBase implementation, this always returns 1. Image returns the

returned from NumericTraits for the pixel type, and VectorImage

returns the vector length set by the user.

Reimplemented in itk::VectorImage< TPixel, VImageDimension >, itk::VectorImage< TPixelType, Dimension >, itk::Image< TPixel, VImageDimension >, and itk::Image< TNode *, VImageDimension >.

Referenced by itk::ImageToImageFilterDetail::ImageToImageFilterDefaultCopyInformation().

◆ GetOffsetTable()

template<unsigned int VImageDimension = 2>

const OffsetValueType* itk::ImageBase< VImageDimension >::GetOffsetTable ( ) const

inline

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 361 of file itkImageBase.h.

◆ GetOrigin()

template<unsigned int VImageDimension = 2>

virtual const PointType& itk::ImageBase< VImageDimension >::GetOrigin ( ) const

virtual

Get the origin of the image. The origin is the geometric coordinates of the index (0,0). The value returned is a Point<double, VImageDimension>. For ImageBase and Image, the default origin is 0.

Referenced by itk::ImageToImageFilterDetail::ImageToImageFilterDefaultCopyInformation().

◆ GetRequestedRegion()

template<unsigned int VImageDimension = 2>

virtual const RegionType& itk::ImageBase< VImageDimension >::GetRequestedRegion ( ) const

inlinevirtual

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 324 of file itkImageBase.h.

◆ GetSpacing()

template<unsigned int VImageDimension = 2>

virtual const SpacingType& itk::ImageBase< VImageDimension >::GetSpacing ( ) const

virtual

Get the spacing (size of a pixel) `of the image. The spacing is the geometric distance between image samples along each dimension. The value returned is a Vector<double, VImageDimension>. For ImageBase and Image, the default data spacing is unity.

Referenced by itk::ImageToImageFilterDetail::ImageToImageFilterDefaultCopyInformation().

◆ Graft() [1/2]

template<unsigned int VImageDimension = 2>

void itk::ImageBase< VImageDimension >::Graft ( const DataObject * )

overrideprotectedvirtual

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.

Reimplemented from itk::DataObject.

◆ Graft() [2/2]

template<unsigned int VImageDimension = 2>

virtual void itk::ImageBase< VImageDimension >::Graft ( const Self * image )

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::DataObject.

◆ Initialize()

template<unsigned int VImageDimension = 2>

void itk::ImageBase< VImageDimension >::Initialize ( )

overridevirtual

Restore object to initialized state.

Reimplemented from itk::DataObject.

◆ InitializeBufferedRegion()

template<unsigned int VImageDimension = 2>

virtual void itk::ImageBase< VImageDimension >::InitializeBufferedRegion ( )

protectedvirtual

Restores the buffered region to its default state This method does not call Modify because Initialization is called by ReleaseData and can not modify the MTime

◆ IsCongruentImageGeometry()

template<unsigned int VImageDimension = 2>

bool itk::ImageBase< VImageDimension >::IsCongruentImageGeometry	(	const ImageBase< VImageDimension > *	otherImage,
		double	coordinateTolerance,
		double	directionTolerance
	)		const

Checks whether the images' pixels with the same index occupy the same physical space. Compares the origin, spacing, and direction for equality within provided tolerances. There is no check for valid regions in between the images.

◆ IsSameImageGeometryAs()

template<unsigned int VImageDimension = 2>

bool itk::ImageBase< VImageDimension >::IsSameImageGeometryAs	(	const ImageBase< VImageDimension > *	otherImage,
		double	coordinateTolerance = `DefaultImageCoordinateTolerance`,
		double	directionTolerance = `DefaultImageDirectionTolerance`
	)		const

Method for creation through the object factory.

◆ PrintSelf()

template<unsigned int VImageDimension = 2>

void itk::ImageBase< VImageDimension >::PrintSelf	(	std::ostream &	os,
		Indent	indent
	)		const

overrideprotectedvirtual

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::DataObject.

◆ RequestedRegionIsOutsideOfTheBufferedRegion()

template<unsigned int VImageDimension = 2>

bool itk::ImageBase< VImageDimension >::RequestedRegionIsOutsideOfTheBufferedRegion ( )

overridevirtual

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.

◆ SetBufferedRegion()

template<unsigned int VImageDimension = 2>

virtual void itk::ImageBase< VImageDimension >::SetBufferedRegion ( const RegionType & region )

virtual

Set 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()

◆ SetDirection()

template<unsigned int VImageDimension = 2>

virtual void itk::ImageBase< VImageDimension >::SetDirection ( const DirectionType & direction )

virtual

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

Each column 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, an 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 columns of the Direction matrix are expected to form an orthogonal right handed coordinate system. But this is not checked nor enforced in itk::ImageBase.

◆ SetLargestPossibleRegion()

template<unsigned int VImageDimension = 2>

virtual void itk::ImageBase< VImageDimension >::SetLargestPossibleRegion ( const RegionType & region )

virtual

Set 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 true conditions.

◆ SetNumberOfComponentsPerPixel()

template<unsigned int VImageDimension = 2>

virtual void itk::ImageBase< VImageDimension >::SetNumberOfComponentsPerPixel ( unsigned int )

virtual

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 in the ImageBase implementation, this always returns 1. Image returns the

returned from NumericTraits for the pixel type, and VectorImage

returns the vector length set by the user.

◆ SetRequestedRegion() [1/2]

template<unsigned int VImageDimension = 2>

void itk::ImageBase< VImageDimension >::SetRequestedRegion ( const DataObject * data )

overridevirtual

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.

template<unsigned int VImageDimension = 2>

virtual void itk::ImageBase< VImageDimension >::SetRequestedRegion ( const RegionType & region )

virtual

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.

◆ UpdateOutputData()

template<unsigned int VImageDimension = 2>

void itk::ImageBase< VImageDimension >::UpdateOutputData ( )

overridevirtual

UpdateOutputData() is part of the pipeline infrastructure to communicate between ProcessObjects and DataObjects. The method of the superclass is overridden 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.

◆ UpdateOutputInformation()

template<unsigned int VImageDimension = 2>

void itk::ImageBase< VImageDimension >::UpdateOutputInformation ( )

overridevirtual

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.

◆ VerifyRequestedRegion()

template<unsigned int VImageDimension = 2>

bool itk::ImageBase< VImageDimension >::VerifyRequestedRegion ( )

overridevirtual

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.
