当考虑可变形运动时，传统的“平滑”约束不适合，因为变形信息取决于位移分量的导数。因此，我们建议使用弹性小位移理论来定义二维（2-D）或三维（3-D）可变形运动估计的新罚函数。该罚函数取决于两个参数。对这些参数的研究表明所提出的函数考虑可压缩或不可压缩变形的能力。
When deformable motion is considered, the conventional "smoothness" constraints are not suitable since the deformation information lies on the derivatives of the displacement components. So we propose to use the small displacement theory of elasticity to define a new penalty function for two dimensional (2-D) or three-dimensional (3-D) deformable motion estimation. This penalty function depends on two parameters, The study of these parameters shows the ability of the proposed functional to take into account compressible or incompressible deformations.
