摘　　要：基于图像的绘制变形技术已成为当前图形学的一个新的研究热点。本文介绍了图像变形和视图变形技术,由Field Morphing方法的基础上,提出了基于控制点的图像变形算法,给出实现变形的原理和步骤。通过实拍人脸图像进行了人脸局部和整体变形实验,其变形结果过渡自然,效果较好,且算法过程简洁,因此具有较好的实用性。视图变形是在图像变形中对物体形状、颜色变形的基础上添加视点变换的一种方法,本文在图像变形的基础上,提出了利用控制点的改进算法,编程实现,中间过渡图像自然逼真。The morphing technology of image-based rending has become a new researchful hotspot in current graph study. This paper introduces the technology of image morphing and view morphing , and proposes a method of image morphing based on the control point by researching foundation in Field Morphing algorithm, gives the theory and implement method of image morphing. The experiments of human face image from actual photography have been carried on local and the whole image morphing. This results show natural transition in image morphing, good effect, and this approach is simple. Therefore the method has a good practicability. View morphing can create new viewpoints to the object＇s shape morphing and color morphing in the image morphing. It gives a improving algorithm by using control points based on image morphing and programs to fulfil the algorithm. The sequence of transition images is natural and realistical.
