Boundary Approximation

I have been playing with snakes( aka active contours ) for a quite long time.
Basic snake is not able to detect boundary correctly. But it is very fast.

I tried to extend the gradient vector field of the image using Laplace equation. it works. But it takes a few seconds to generate the vector field.. :( , now i am thinking about using distance transform to generate the vector field.

See the video below to see snake in action.

That's cool KD. In the downside there's something fishy. please check that tool. This reminds of the selection tools of Photoshop
