Follow-up Comment #1:

You are correct, the current implementation seems indeed to be wrong. I added
a failing test to the function
http://hg.code.sf.net/p/octave/image/rev/de3b5ff642f0

I would appreciate if you could submit a patch to fix this (it may be helpful
to look into the devel/
http://hg.code.sf.net/p/octave/image/file/de3b5ff642f0/devel

My understanding is that some of those files helped on developing this
functions but that was way before I got involved with Octave).
