摘要
基于有理样条插值曲线,提出了一种新的图像变形算法.首先用双三次有理样条插值曲线表示图像,然后将变形因子作用于待变形的图像,从而获得变形效果.实验表明本算法变形模型简单,易于操作,能够精确控制变形范围.
A new method of image free-form deformation is presented based on the rational interpolation curves.First of all,a cubic spline is constructed for the values of an image.Then an extension factor to deform the parametric curve needed deformation,through the controlled parameter is changed,the ideal deformation effect can be got.The experiments show that this method is simple and easy to control.
