[Insight-users] container for iterators of images

[Bradley Lowekamp]

Hello Hila,

I'd use a different approach.

I would first use the ComposeImageFilter to join the set of input images into a  single VectorImage.

Then I'd implement a UnaryFunctor to compute the 1-norm, or sum of the vector components. This wiki example may be of help on how it implement the functor:

> 
>             output_val = it->Get() + output_val;  //get values from each image and insert in the output image
>             // How do I forward the image's iterator from here ?????


Perhaps this is what you want:

 ++(*it);
 
This dereferences, the std::list<constIteratorType>::iterator type to a constIteratorType type, where you can use the prefix increment operator.
