摘要
图像局部变形技术是图像处理领域的一个分支,它只改变图像中指定区域范围内的特征而保持其他区域不发生变化。文中在径向基函数的基础上,提出了一种基于椭圆变形域的图像局部变形的算法,并讨论了函数中关键参数的选取对变形效果的影响;通过对变形区域的影响半径R和影响系数s的设置,控制图像局部变形的区域,从而解决了图像变形过程中产生的重叠映射;最后,介绍了图像局部变形的算法流程,利用VC++6.0和OpenCV搭建实验平台对算法进行了验证,实现了交互模式下的图像局部变形。
Local image warping technology is a branch of image processing. It only changes the image features in a specified area and maintain other regions. In this paper,a local elliptical area image warping algorithm based on radial basis function is proposed,and a de- tailed discussion is given on the key parameters of this algorithm. Then,the local warping area is controlled by the setting of influential mdins R and influential coefficient s to solve the overlap mapping in the image warping process. Finally, the algorithmic process of local image warping is introduced. An experiment platform is built to validate the algorithm by VC＋＋6.0 and OpenCV,achieved local image warping based on interactive mode.
