提出了一种基于移动最小二乘的图像变形方法，该方法使用了各种线性函数，包括仿射变换、相似变换和刚体变换。这些变形是逼真的，给用户一种操纵真实世界对象的感觉。我们还允许用户使用点集或线段来指定变形，后者对于控制图像中存在的曲线和轮廓很有用。对于这些技术中的每一种，我们都提供了简单的闭合形式的解决方案，可以产生可以实时执行的快速变形。
We provide an image deformation method based on Moving Least Squares using various classes of linear functions including affine, similarity and rigid transformations. These deformations are realistic and give the user the impression of manipulating real-world objects. We also allow the user to specify the deformations using either sets of points or line segments, the later useful for controlling curves and profiles present in the image. For each of these techniques, we provide simple closed-form solutions that yield fast deformations, which can be performed in real-time.
