针对当前存在的大量数值型数据，将连续型数据离散化，有利于计算机直接处理变量。(In view of the existence of a large number of numerical data, the discretization of continuous data is conducive to deal directly with the variable computer.)

说明：  图像的加密与解密，非常好的一个例子，可以学到不少的好东西。。(Image encryption and decryption, a very good example, can learn a lot of good things. .)

是matlab编程风格的好文章。读者可以通过这篇文章提高自己matlab代码的书写效率(Matlab programming style is a good article. Readers of this article can improve their efficiency in writing code matlab)

说明：  图像配准程序，matlab编写,本人已验证过的好使的程序(images resgister)

说明：  此压缩文件中包含了对退化图像进行复原的Matlab源代码和处理后的图像。。。(This compressed file contains the restoration of degraded images Matlab source code and the processed image. . .)

基于non-local means的maltab算法(nlm' s maltab algorithm)

对任意一组输入的字符串进行哈夫曼编码，然后解码(Huffman coding and decoding on a set of strings)

empirical formula with kaiser clc clear all fs=1000 fc=250 df=50 r=0.001 f=fc/fs dw=2*pi*(df/fs) a=-20*log(r) n=floor(((a-8)/(2.285*dw))+1) if a>50 b=0.1102*(a-8.7) elseif a>=21 && a<=50 b=0.5842*((a-21)^0.4)+0.07886*(a-21) elseif a<21 b=0.0 end w=kaiser(n,b) for i=1:n if i~=(n-1)/2 hd(i)= (2*f*sin((i-((n-1)/2))*2*pi*f))/((i-((n-1)/2))*2*pi*f) elseif i==(n-1)/2 hd(i)=2*f end end for j=1:n h(j)=w(j)*hd(j) end subplot(3,1,1), plot(w) subplot(3,1,2), plot(h) subplot(3,1,3), plot(h,n)

说明：  仍工智能算法基于粒子群算法的优化程序，用与分类等其他他的地方也有其他的作用等着你们下载哦(atrificial nbnbnbnbnbnbnbnbnnbnbnnbnbnnbnbn)

经典的RLS算法，相信对做自适应滤波方向的人很有用哦(Classical RLS algorithm, adaptive filter do believe that one very useful direction Oh)
