摘要: 在计算光流场的基础上,提出了snake算法中一种新的外部能量函数,并利用光流场的运动矢量来预测下帧图像中snake的初始值,不仅与无预测的算法相比能提高收敛的速度,而且收敛结果更贴近于目标的本身。实验证明了该文算法的优越性。
关键词: snake模型, 光流场, 运动矢量
Abstract: On the basis of optical flow field computation,we redefine outer energy function in the general snake model and utilize motion vector of light-fluid field to predict the initial values of snake algorithm in subsequent frames.Hence,fast extraction of objective contour is achieved.
Key words: snake model, optical flow, motion vector
