Hi Luis,
    In my program I have a while loop where I create an intermediate image
which is the output of a sequence of filters and I perform some
calculations on this image. Let me call this image1. Let me assume that I
want to set this as the output of a filter for which FinalFilter within the
while
loop. 

Would I need to set a New pointer to image1 outside the while loop like:

ImageType::Pointer image1 = ImageType::New();

And then within the while loop I do:
while(..) 
{
...
...
...
image1 = FinalFilter->GetOutput();
...
...
}

Is the assignment statement in the while loop correct, or would I need to
set the result of FinalFilter to image1 in some other way?
I also have a similar question for iterators. If my iterator is imit, how
would I create an iterator outside the while loop and then set it
to an image and corresponding region inside while loop?

Hope my questions are clear.

Thanks
Radhika
