| 摘 要： | 介绍一种迭代函数构造方法，证明其具有收敛性；在此基础上，推导出一个自相似匹配条件，使得对于任一图象，根据匹配条件，可构造一组迭代函数，迭代结果与原图象相应的象素灰度值最大误差能控制在给定值内；并且求出满足匹配条件参数的解；最后给出一种自适应分割迭代函数构造算法．

| Abstract: | A method of constructing iterated functions is instroduced, and its convergence is proved. A self-affine macthing condition is derived and its solution is given. Base on this condition, a group of iterated functions can"be constructed for any given image. The maximum grey level error between iterated image and original image can be control under a given vale. On the end a adaptive algorithm for constructing 'iterated functions is provided. |
