ridge finder algorithm?

Can anyone point me to an algorithm for detecting ridges in a monochrome image? I'd like to end up
with a binary image comprised of single-pixel width lines along the ridges. I can think of several
ways to do it, mostly involving looping over a range of thresholdis, but these methods seem very
inefficient.

Thanks.
