经典矩量法点匹配程序，重推导，注释说明详细(Classical point matching moment method procedure)

这是一个matlab关于分数阶混沌的源程序代码，通过该程序可画出混沌图，这对初学者很有帮助。我已经调试过了。(This is a matlab fractional order to chaos on the source program code, through the program can draw a picture of the fractional order, to beginners helpful. I have the commissioning)

说明：  本程序主要对遥感图像实现三种处理：几何校正、图像增强和图像配准。这三种处理都可以独立实现，然而对于原始的遥感图像将这三种处理依次进行效果更佳。(This program mainly deals with three kinds of remote sensing image processing: geometric correction, image enhancement and image registration. These three kinds of processing can be realized independently, but for the original remote sensing image, the effect of these three kinds of processing in turn is better.)
