一种基于B样条曲线的图像变形算法

An Image Deformation Algorithm Based on B-spline Cureves

利用任意给定的数个点,得到两条B样条曲线,并建立映射关系.对物体的网格控制点实现映射,然后利用插值算法实现目标源图像的映射,描绘出各个像素点,从而实现变形.实验表明该算法易于交互和局部控制,适应于几何造型和计算机动画领域.

The mapping function of two Bspline curves from many random controlled points is given.We have realized the mapping relation shop of webcontrolled points between source and object.An interpolation algorithm about object to source mapping for painting every pixel is established. The experiment shows that our method is intuitive, easy to control. It can be applied in both geometric modeling and computer animation.
