摘　　要：主动轮廓模型(也称为snake模型)是在由轮廓自身特征决定的内部能量和图像特征决定的外部能量共同作用下能量极小化的轮廓曲线,可用于边缘检测、运动跟踪、图像匹配、计算机视觉和三维重构等图像处理领域。从snake模型的数学模型出发,介绍了两种常用的snake模型——气球力模型和GVF模型,阐述了近十年来基于经典snake模型的能量改进算法,对比说明了对当前求解snake能量极小的算法,并对未来的研究方向进行了讨论和展望。It contour model（also named snake model）is an energy-minimizing contour guided by the internal energy of the contour and the external energy of the image ,which can be used in many applications such as edge detecting, motion tracking, image matching,computer vision,and three-dimensional （3- D） reconstruction. On the basis of the mathematical model of the snake ,two normal models ,the balloon snake model and the GVF snake model,are introduced,and many improved algorithms on the basis of classic snake model in recent years are elaborated,and many practical algorithms for solving energy minimization are detailed and compared. Furthermore,possible future research orientations are presented and discussed.
