该类方法主要指的是活动轮廓模型(active contour model)以及在其基础上发展出来的算法,其基本思想是使用连续曲线来表达目标边缘,并定义一个能量泛函使得其自变量包括边缘曲线,因此分割过程就转变为求解能量泛函的最小值的过程,一般可通过求解函数对应的欧拉(Euler.Lagrange)方程来实现,能量达到最小时的曲线位置就是目标的轮廓所在。-Such methods mainly refers to the active contour model (active contour model) and the algorithm developed at its foundation, the basic idea is the use of a continuous curve to express the target edge and define an energy functional so that its arguments include edge curve Therefore segmentation process is transformed into solving process minimum energy functional, and can be obtained by solving the corresponding Euler function (Euler.Lagrange) equation to achieve, achieve energy curve position the hour is the goal of the contour lies.
