Detailed Description

template<unsigned int VImageDimension>
class itk::ImageRegionSplitter< VImageDimension >

Divide a region into several pieces.

ImageRegionSplitter divides an ImageRegion into smaller regions. ImageRegionSplitter is used by the StreamingImageFilter to divide a requested output region into a series of smaller requests of the pipeline. This object has two basic methods: GetNumberOfSplits() and GetSplit().

GetNumberOfSplits() is used to determine how may subregions a given region can be divided. You call GetNumberOfSplits with an argument that is the number of subregions you want. If the image region can support that number of subregions, that number is returned. Otherwise, the maximum number of splits less then or equal to the argumen be returned. For example, if a region splitter class only divides a region into horizontal slabs, then the maximum number of splits will be the number of rows in the region.

GetSplit() returns the ith of N subregions (as an ImageRegion object).

This ImageRegionSplitter class divides a region along the outermost dimension. If the outermost dimension has size 1 (i.e. a volume with a single slice), the ImageRegionSplitter will divide the region along the next outermost dimension. If that dimension has size 1, the process continues with the next outermost dimension.

Other ImageRegionSplitter subclasses could divide an image into more uniform shaped regions instead of slabs.

Member Function Documentation

template<unsigned int VImageDimension>

virtual::itk::LightObject::Pointer itk::ImageRegionSplitter< VImageDimension >::CreateAnother ( void ) const

virtual

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::Object.

Reimplemented in itk::ImageRegionMultidimensionalSplitter< VImageDimension >.

template<unsigned int VImageDimension>

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

inlinestatic

Dimension of the image available at run time.

Definition at line 82 of file itkImageRegionSplitter.h.

template<unsigned int VImageDimension>

virtual const char* itk::ImageRegionSplitter< VImageDimension >::GetNameOfClass ( ) const

virtual

Run-time type information (and related methods).

Reimplemented from itk::Object.

Reimplemented in itk::ImageRegionMultidimensionalSplitter< VImageDimension >.

template<unsigned int VImageDimension>

virtual unsigned int itk::ImageRegionSplitter< VImageDimension >::GetNumberOfSplits	(	const RegionType &	region,
		unsigned int	requestedNumber
	)

virtual

How many pieces can the specifed region be split? A given region cannot always be divided into the requested number of pieces. For instance, if the numberOfPieces exceeds the number of pixels along a certain dimensions, then some splits will not be possible. This method returns a number less than or equal to the requested number of pieces.

Reimplemented in itk::ImageRegionMultidimensionalSplitter< VImageDimension >.

template<unsigned int VImageDimension>

virtual RegionType itk::ImageRegionSplitter< VImageDimension >::GetSplit	(	unsigned int	i,
		unsigned int	numberOfPieces,
		const RegionType &	region
	)

virtual

Get a region definition that represents the ith piece a specified region. The "numberOfPieces" must be equal to what GetNumberOfSplits() returns.

Reimplemented in itk::ImageRegionMultidimensionalSplitter< VImageDimension >.

Method for creation through the object factory.

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.
