[Insight-users] itk::ChangeLabelImageFilter

[Miller, James V (GE, Research)]

I think Dirk Padfield or Tim Kelliher wrote the ChangeLabelImageFilter.  I'll have one them take
a look at the SetChangeMap() issue.

I see. But what do I do wrong:

This works:

	ChangeLabelFilterType::ChangeMapType changeMap;
// some code to set the map
	LabeledImageIteratorType watershedIt( watershedImage,
watershedImage->GetBufferedRegion() );
	for(watershedIt.GoToBegin(); !watershedIt.IsAtEnd(); ++watershedIt)
		watershedIt.Set( changeMap[ watershedIt.Get() ] );

But this does not:
	ChangeLabelFilterType::Pointer labelChanger = ChangeLabelFilterType::New();
	labelChanger->SetInput( watershedImage );
	labelChanger->SetChangeMap( changeMap );
	labelChanger->Update();
	LabeledImageType::Pointer labelChangedImage = labelChanger->GetOutput();

Thanks for your help!

Henning
