Asking about the "best" segmentation code for any particular purpose requires a prediction about the entire future of computation and mathematical analysis. I've got a method scrawled in the dust of my desk here that might be Nobel Prize winning (or perhaps not) and not to be surpassed before the Sun goes nova, but that doesn't mean that it is the best method, since there might be a hyperspectral polybayron post-quantum method waiting for us to translate from the bead-braiding language of the small furry creatures from Alpha Centurai a mere 11 billion years from now.
A method either is the best, or it isn't the best. And I, for one, never bet against the cleverness of the small furry creatures.
