Study on image deformation based on moving least squares
利用移动最小二乘法实现图像变形

Using moving least squares, an image deformation method was proposed based on control curves. Firstly, control curves were created by setting key points according to shape information or topology relationship, and were moved to new positions. Then affine, similar and rigid transformations were computed to realize various image deformations using Moving Least Squares. Experiments show that image shape and outline information can be realized by this method and the deformation result is satisfactory and realistic.
