On the basis of a constructed edge map, instantaneous position information of Snakes was attained with the statistical method, while the information contributes to the solution to problems of difficulty in converging at concave edge and controlling the convergence condition and the problem of the step oneness.

构造图像边界信息图，用统计学方法获得Snakes的即时位置信息，解决传统模型的难于收敛到凹型边界、收敛条件不易控制以及移动步长的单一等问题。
