These functions implements the basic snake segmentation contour, as introduced by Kass et al.

Algorithm:
A snake is an active (moving) contour, in which the points are attracted by edges and other image boundaries. To keep the contour smooth, a membrane and thin plate energy is used as contour regularization.

Implementation:
All code is well commented, and is probably easy readable. It includes,
- A balloon force, which is not in the original paper
- Binary image segmentation result,
- The "Gradient Vector Flow" (GVF) method.
- 3D implementation, including parameter to keep the mesh from self-intersecting

Try the example in the help of function Snake.m !
