摘要：
An adaptive Snake algorithm is presented in this paper. To every point in the initial position, the energy of the point in its neighbors is calculated by Greedy algorithm. If the target contour is not included in its neighbors, we can increase the radius of its neighbors and calculate the energy of all the points again until target contour is included. The target contour can be got by iterating once. In addition, the convergent radius is increased. It can also be applied to objects of high convexity. Comparative experiments indicate the validity of this method.
