Hi
Does anybody here know a simple way to find the zerocrossings in an
image in Octave?
I usually do something like this (where f is the image (or 2d function))
zerocrossings = bwmorph(f>=0, "remove");
but then I depend on bwmorph which only is octave-forge (which I don't
have at school).
Any help would be great,
\Søren
