Rrs_inversion_RPFG

this is very useful file that simulate the memory polynomial method.

说明：  运用光反馈测距的部分程序，运用此程序可实现运用。希望大家参考，并且适当的修改。(The use of optical feedback ranging part of the process, use can be achieved using this procedure. Hope your reference, and the appropriate changes.)

对一副M*N大小的图像重复使用截频为D0的高斯低通滤波器进行滤波。假设K为滤波次数。并从理论上说明当K足够大时的滤波结果及产生原因(Right an M* N size of the image is repeated using the cutoff frequency for the D0 of a Gaussian low-pass filter for filtering. Assuming K is filtering times. And filtering results when K is large enough and theoretically causes)
