详细说明： Description 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 Vect or Flow" (GVF) method. - 3D implementation, including parameter to keep the mesh from self-intersecting Try the example in the help of function Snake.m !
