ok, I think I get it

you can easily create your own filter to perform that transform by  
subclassing the UnaryFunctorImageFilter. You can look at  
NotImageFilter for an example.

That said, it seem a little uncommon to store several segmentations  
that way. Perhaps should you split them in several images?
