Summary

0011993: Streaming and InPlaceImageFilter

Description

Problem with InPlaceImageFilter when using streaming. When connecting the input of an InPlaceImageFilter to a filter that has been updated and try to write the output of this filter with SetNumberOfStreamDivisions set e.g. to 2, only the first half of the filter is updated.

Steps To Reproduce

Compile the test program:
//////////////////////////////////////////////////////////////
#include <itkImageFileReader.h>
#include <itkImageFileWriter.h>
#include <itkMultiplyByConstantImageFilter.h>

int main(int argc, char * argv[])
{
typedef double PixelType;
const unsigned int Dimension = 3;
typedef itk::Image< PixelType, Dimension > ImageType;

typedef itk::ImageFileReader<ImageType> ReaderType;
ReaderType::Pointer reader = ReaderType::New();
reader->SetFileName(argv[1]);
reader->Update();

typedef itk::MultiplyByConstantImageFilter< ImageType, PixelType,
ImageType > FilterType;
FilterType::Pointer filter = FilterType::New();
filter->SetInput(reader->GetOutput());
filter->SetConstant(0.);
filter->SetInPlace(atoi(argv[2]));

typedef itk::ImageFileWriter< ImageType > WriterType;
WriterType::Pointer writer = WriterType::New();
writer->SetInput(filter->GetOutput());
writer->SetFileName(argv[3]);
writer->SetNumberOfStreamDivisions(2);
writer->Update();

return EXIT_SUCCESS;
}
//////////////////////////////////////////////////////////////

Use a test image input.mha and run successively:
$ testPgm input.mha 0 output0.mha
$ testPgm input.mha 1 output1.mha

output0.mha and output1.mha should be the same but are not: only half of output1.mha is set to 0 instead of the full image.

Notes
(0025849) Bradley Lowekamp (developer) 2011-03-21 15:44	I believe this issue is related to the InPlaceImageFilter not checking that the input buffered region, equals the output buffer.
