摘要
文中利用两条任意折线构成两个控制多边形，得到两条Ｂｅｉｚｅｒ曲线，利用两曲线作为控制线对图像轮廓多边形内的网格控制点进行映射，最后利用一个快速有效的插值算法进行目标－源映射，描绘各个像素点实现变形效果．实验证明，该算法快速有效，结果形象逼真。
Two Beizer curves from two random control ploygons are obtained firstly in the present paper,which are constituted of two discount lines; then these curves are taken as control lines to map those web control points within a ploygon of outline;Finally, an intuitive and expeditious interpolation algorithm realizing object\|source mapping is used to paint every pixel. Experimental results of image deformation using the algorithm prove that this algorithm is intuitive, expeditious, and practical.
