可变形模型对于范围广范的一系列视觉问题给出了统一的解决方法，并在轮廓提取、运动跟踪、3D重建、立体匹配等方面得到了广泛应用。从弹性理论出发，揭示了可变形模型的物理本质，井对可变形模型的参数赋予了现实的物理意义。其结论将有助于更好地理解可变形模型的变形行为，并为今后应用弹性理论中的方法研究可变形模型莫定了基础。

Deformable models provide a unified account of a number of visual problems, including contour extraction, motion tracking as well as 3D reconstruction and stereo matching. To get a reality-based interpretation of the deformable model and its parameters, an approach originates from the theory of elasticity is proposed. The conclusion is helpful to further understanding the behavior of deformable model. A new way is provided to research deformable models from the theory of elasticity.
