摘要： 主动轮廓模型(snake 模型)融合了图像底层信息与外部高层信息，在目标跟踪边缘检
测图像分割和逆向工程中得到了广泛应用，是目前计算机视觉领域活跃度较高的研究方向。传统
snake 模型和部分改进的主动轮廓模型都具有明确的力学意义。首先对传统 snake 模型以及采用 B
样条参数化表示的 B-snake 模型的力学原理进行了阐述，然后针对传统 snake 模型的缺陷，从力
学角度介绍了几种改进的主动轮廓，并且基于拉格朗日动力学原理对 snake 模型的驱动过程以及
惯性力主动轮廓进行了介绍，最后进行了总结及未来研究工作的展望。

Abstract: Snake models compromises low-level knowledge of images and the high-level knowledge of
images. Snake models have been widely used in target tracking, edge detection, image segment and
reverse engineering. It is considered as an active research field. Clear mechanic theory is included in
Traditional snake models and some improved active contour models. The mechanic theory of traditional
snake models and the B-snake models which is based on the theory of B-spline is presented firstly.
Because of some defects in traditional snake model, some improved active contour models also are
discussed from the mechanics view. In additional, the convergence process of the snake models and the
active contour with inertia force are interpreted by Lagrange dynamics. In the end, the summary and the
expectation are proposed.
