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< TPixel, 3 > is the same as a Image< VariableLengthVector< TPixel >, 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< TPixel > 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< TPixel >.

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.

virtual::itk::LightObject::Pointer itk::VectorImage< TPixel, VImageDimension >::CreateAnother ( void  ) const

Reimplemented from itk::ImageBase< VImageDimension >.

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.

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

Reimplemented from itk::ImageBase< VImageDimension >.

template<class TPixel, unsigned int VImageDimension = 3>
const PixelType itk::VectorImage< TPixel, VImageDimension >::GetPixel ( const IndexType index) const
inline

Get a pixel (read only version).

For efficiency, this function does not check that the image has actually been allocated yet. Note that the method returns a pixel on the stack.

Definition at line 233 of file itkVectorImage.h.

template<class TPixel, unsigned int VImageDimension = 3>

template<class TPixel, unsigned int VImageDimension = 3>
virtual const VectorLengthType& itk::VectorImage< TPixel, VImageDimension >::GetVectorLength ( )
virtual

Set/Get macros for the length of each vector in the vector image

template<class TPixel, unsigned int VImageDimension = 3>
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.

Reimplemented from itk::ImageBase< VImageDimension >.

template<class TPixel, unsigned int VImageDimension = 3>
virtual void itk::VectorImage< TPixel, VImageDimension >::Initialize ( )
virtual

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

Reimplemented from itk::ImageBase< VImageDimension >.

template<class TPixel, unsigned int VImageDimension = 3>
static Pointer itk::VectorImage< TPixel, VImageDimension >::New ( )

private
template<class TPixel, unsigned int VImageDimension = 3>
PixelType itk::VectorImage< TPixel, VImageDimension >::operator[] ( const IndexType index)

Access a pixel. This version cannot be an lvalue because the pixel is converted on the fly to a VariableLengthVector.

For efficiency, this function does not check that the image has actually been allocated yet.

Definition at line 258 of file itkVectorImage.h.

template<class TPixel, unsigned int VImageDimension = 3>

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::ImageBase< VImageDimension >.

template<class TPixel, unsigned int VImageDimension = 3>
virtual void itk::VectorImage< TPixel, VImageDimension >::SetNumberOfComponentsPerPixel ( unsigned int  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() )

ImageBase, VectorImage

Returns/Sets the number of components in the image. Note that in the ImageBase implementation, this always returns 1. Image returns the

returns the vector length set by the user.

template<class TPixel, unsigned int VImageDimension = 3>

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

Dimension of the image. This constant is used by functions that are templated over image type (as opposed to being templated over pixel type and dimension) when they need compile time access to the dimension of the image.
