几个关于利用傅里叶变换进行谐波分析的代码。有详细的变换过程，比较适合想了解原理的初学者。(Several on the use of Fourier transform for harmonic analysis of the code. The transformation process in detail, more suitable for beginners would like to know the principle.)

说明：  function [ret,x0,str,ts,xts]=smg(t,x,u,flag) smg is the M-file description of the SIMULINK system named smg. The block-diagram can be displayed by typing: smg. SYS=smg(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

The guided filter can be used as an edge-preserving smoothing operator like the popular bilateral filter, but has better behaviors near edges. The guided filter is also a more generic concept beyond smoothing: it can transfer the structures of the guidance image to the filtering output, enabling new filtering applications like dehazing and guided feathering. Moreover, the guided filter naturally has a fast and non-approximate linear time algorithm, regardless of the kernel size and the intensity range. Currently it is one of the fastest edge-preserving filters.
