大津算法是关于图像处理中分割的重要算法，是又日本人的最先使用的。自动寻找分割点(Otsu algorithm is divided on the importance of image processing algorithms, is the first Japanese to use it. Automatically find split points)

说明：  有限差分法求解一维扩散方程。使用Crank-Nicolson格式求解PDE方程，并与真实解析解u(t,x)=e^(x+0.1t)比较。 一维扩散方程的有限差分法，采用隐式六点差分格式。(Finite difference method for solving one dimensional diffusion equation)

一个多线程管理的程序管理器，适合程序开发者即大型计算者使用(multiple line， useful for program developer)

Blind Equalizer 的演算法主要是利用CMA及 LMS 的配合，当CMA将EYE打开，使讯号趋近于正确值，就切换到LMS，利用Slicer的输出当作training sequence来调整Equalizer的系数，而Carrier Recovery 的部份，则是将phase error track出来(Blind Equalizer algorithm is the use of the CMA and LMS tie, When the CMA will EYE open, signaling close to the correct value, it switched to the LMS. SLICER use of the output as training sequence to adjust Equalize The coefficient r, and some of Carrier Recovery, the type of track out phase error)

这两个小程序是matlab的.m文件，06为采用二维中值滤波函数medfilt2对受椒盐噪声干扰的图像滤波，07采用matlab中的函数filter2对受噪声干扰的图像进行均值滤波。(these two small procedure is Matlab. M documents, 06 for 2D median filtering function medfilt2 right by the Salt and Pepper image noise filtering, 07 using Matlab filter2 the function of noise interference by the image filtering.)
