The kernel is rather small (5x5), at least for this test. I may have
larger ones for non-morphological filtering.

I am. That is, I'm setting NDEBUG and I compile with -O. I guess that
qualifies as release mode, right?

Thanks for the tip! One question, though: I cannot find any occurence of
DisconnectPipeLine() in the software guide. I assumed that would be the
best place to start with when learning ITK, but apparently not. Where
should I look for information like this?

correct?
