自适应滤波器的LMS算法，主要用MATLAB实现了其算法(LMS adaptive filter algorithm, the main MATLAB realize its algorithm)

一种全局的直接优化方法，优化过程中无需用到目标函数的导数信息。(The purpose of this brief user guide is to introduce the reader to the DIRECT optimization algorithm, describe the type of problems it solves, how to use the accompanying MATLAB program, direct.m, and provide a synopis of how it searches for the global minium.)

说明：  对信号进行频域特征提取，先通过傅里叶变换得到信号频谱，再计算频谱特征，包括重心频率，均方频率和频率方差(Firstly, the frequency spectrum of the signal is obtained by Fourier transform, and then the spectrum characteristics, including center of gravity frequency, mean square frequency and frequency variance, are calculated.)

一段可以借鉴的增强图像效果的matlab代码，能达到很好的效果，可以参考。(Some can learn from the matlab code, can achieve good results, you can reference.)
