Image Deformation Using Moving Least Squares

MLS算法论文，We provide an image deformation method based on Moving LeastSquares using various classes of linear functions including affine,similarity and rigid transformations. These deformationsare real-istic and give the user the impression of manipulating real-worldobjects. We also allow the user to specify the deformations usingeither sets of points or line segments, the later useful for control-ling curves and profiles present in the image. For each of thesetechniques, we provide simple closed-form solutions that yield fastdeformations, which can be performed in real-time.
