Abstract

Abstract: Combined with Moving Least Squares method, a deformation function based on control points and area was defined. A localization processing method for image deformation was proposed which extended to vector graph deformation. After adding control points to control deformation and setting the target deformation zone as control area, control points were controlled to deform image and vector graph, which could produce affine transformation, similarity transformation and rigid transformation results. Experiments show that, this method can inhibit boundary aliasing as well as ensuring graphics and image local deformation result smoothness. By applying it to vector graph deformation, multiple complex deformation effects can also be customized.
