空间谱估计算法，是研究信号噪声比的。效果还可以(Spatial spectrum estimation algorithm, is to study the signal-noise ratio. Effects can also be)

求最优步长，最优步长对应的设计变量及函数值。(Seek the optimal step length, step length corresponding to the optimal design variables and function values.)

说明：  （7，4）循环编码m文件基于matlab(（7，4）convenc encoder m file base on matlab )

说明：  应用于各种雾天条件下对图像进行雾去除，可以得到清晰无雾的效果图，是一个不错的图像恢复工具(a method of haze removal,we can gain a haze-free image)

著名的FastICA 算法，最新版本，修改了以前的Bug.(famous Fast algorithm, the latest version, which amended the previous Bug.)

学习中整理的一些处理模糊图像的函数，多数来自《数字图像处理MATLAB版》中的一些函数，希望能给大家帮助(Learning some sort of deal with the ambiguity function of the image, mostly the Digital Image Processing MATLAB version of some of the functions, I hope everyone can help)

Find roots of a polynomial with very high degree and multiplicity by this compact routine.

在windows matlab环境下实现卷积模型下的信号盲源分离(In matlab simulation environment， convolutive BSS problem is solved.)

用于仿真高斯噪声、单音干扰、多音干扰以及不同占空比下干扰条件下的扩频系统性能及误码率(For the simulation of Gaussian noise, single tone interference, spread spectrum system performance in multi-tone interference and interference under the conditions of different duty cycles and bit error rate)

图像处理中，图像质量的评价指标，信噪比等等(quality assessments of image in image processing)
