Detailed Description

template<class TInputImage, class TOutputImage>
class itk::StreamingImageFilter< TInputImage, TOutputImage >

Pipeline object to control data streaming for large data processing.

StreamingImageFilter is a pipeline object that allows the user to control how data is pulled through the pipeline. To generate its OutputRequestedRegion, this filter will divide the output into several pieces (controlled by SetNumberOfStreamDivisions), and call the upstream pipeline for each piece, tiling the individual outputs into one large output. This reduces the memory footprint for the application since each filter does not have to process the entire dataset at once. This filter will produce the entire output as one image, but the upstream filters will do their processing in pieces.

unsigned    int
 

Get the number of pieces to divide the input. The upstream pipeline will be executed this many times.

Reimplemented from itk::ProcessObject.

void itk::StreamingImageFilter< TInputImage, TOutputImage >::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::ImageToImageFilter< TInputImage, TOutputImage >.

template<class TInputImage, class TOutputImage>
virtual void itk::StreamingImageFilter< TInputImage, TOutputImage >::SetNumberOfStreamDivisions unsigned int    _arg [virtual]
 

Set the number of pieces to divide the input. The upstream pipeline will be executed this many times.

virtual void itk::StreamingImageFilter< TInputImage, TOutputImage >::UpdateOutputData DataObject   output [virtual]
 

Override UpdateOutputData() from ProcessObject to divide upstream updates into pieces. This filter does not have a GenerateData() or ThreadedGenerateData() method. Instead, all the work is done in UpdateOutputData() since it must update a little, execute a little, update some more, execute some more, etc.

Reimplemented from itk::ProcessObject.
