[Insight-users] Memory-related Question

[salah]

> Hello all,
> 
> I have a question related to memory allocation in itk filters.
> 
> when I have an itk image in some program, defined in terms of a smartpointer. For example:
> 
>    ImageType::Pointer exampleImage = ImageType::New();
>    exampleImage->SetRegions( region);
>    exampleImage->Allocate();
> 
> Now if I feed this image as input to some itk filter that inherits 
> from ItkImageToImageFilter (by  filter->SetInput(exampleImage); ), 
> would this filter create/allocate a copy of the exampleImage? Or it 
> just uses the one allocated by/in the calling module?
> 
> My question is due to the fact that an itk program of me hangs (sometimes
> terminates abnormally, reporting an error with the graphic card) with
> big images (512x512x150) but behaves well with smaller ones. 
> 
> Many thanks,
