摘要
描述一种矩形图像拉伸为任意四边形图像C++实现算法,此算法通过线性变换方式,建立起一个任意四边形图像上的任意一点与标准矩形图像中确定点的映像函数。经对比测试,该算法效率高效,稍加扩充可应用于更为复杂的变换中。
Analyses a kind of linear free stretching algorithm, the purpose of this algorithm is to convert a standard rectangular image to arbitrary quadrilateral image. The main function is to create a reflection from arty point of the arbitrary quadrilateral image to a special point of the rectangular image. With high efficiency, this algorithm can be used on more complicated image transformation after a little expansion on it.
