[ITK-users] Watershed filter: vary level parameter without running update

Hi,

The documentation for the watershed filter says that

/"The Level parameter can be used to create a hierarchy of output images in
constant time once an initial segmentation is done. A typical scenario might
go like this: For the initial execution of the filter, set the Level to the
maximum saliency value that you anticipate might be of interest. Once the
initial Update() of this process object has finished, the Level can be
manipulated anywhere below the initial setting without triggering a full
update of the segmentation mini-pipeline. All that is now be required to
produce the new output is a simple relabeling of the output image."/

I was interested in knowing how to access these hierarchy of output images,
once the update has been performed.

Thank you.

Best,
Bipul Tarafdar
