models. Such a model iteratively evolves toward the relevant anatomy according
to global energy minimization. The functional energy represents the confluence of
physics and geometry. The latter represents an object shape and the former places
constraints on how the shape may vary over space and time. For these models to
produce accurate results, the initial contour should be close to the desired bound-
