摘要
图像变形技术是将一副图像平滑自然地变换到另一幅图像的方法,主要通过源图像与目标图像的映射关系计算出源图像中像素点在目标图像中的坐标,最终实现图像的变形.阐述了图像变形的相关概念和方法,并给出了球面变形和椭圆变形的算法理论.
Image warping technique is a method of the image will be transformed smoothly and naturallyto another image, mainly through the source image and the target image mapping relation to calculate the source image pixel in the target image coordinates, to reach the image warping. In this paper, the concepts and methods of image warping were expounded, and the algorithm theory on the spherical de- formation and elliptical deformation were gave out.
