Patch Constrained Deformation Technique

A reference patch is demarcated to define the local feature of object to be deformed,while another patch predicts the shape that the reference patch will move to.After the object is bound to the patches,three transformations：scaling,rotation and translation,are performed to all the points needed to be deformed. With our algorithm,the deformation looks natural.Furthermore,additional scaling and offsetting factors can be used to extend deformation effects.
