 Re: [Insight-developers] SmartPointers If you assign the output of a filter to a smart pointer, e.g.

ImageType::Pointer ip = filter->GetOutput();
filter = FilterType::Pointer(); // force filter deletion by assigning empty smart pointer.

the pointer ‘ip’ should still point to a valid image, since when the filter is deallocated, ‘ip’ still holds a reference.

Hi,
>>I am using a pipeline made up of several filters. Since the size of my image is very big, the application usually crashes because I lack of memory. My first idea to solve this problem was to, at a certain point, recover the resulting image and erase all the filters that I have been using up to that point. I use this image to feed up the rest of the pipeline.
