用db4小波分解六层：s=a6+d6+d5+d4+d3+d2+d1(db4 wavelet decomposition of six layers: s = a6+ d6+ d5+ d4+ d3+ d2+ d1)

non local mean filter commande example I =mat2gray(imread( eight.tif )) mn= 0 vr= 0.02 J = imnoise(I, gaussian ,mn,vr) add noise output=NLmeansfilter3(J,7,3,0.1)

【matlab编程代做】4B5B编码器线 可以作为参考使用([Do] matlab programming generation 4B5B encoder line can be used as references)

说明：  由Nasa提供，在Matlab裡面調用Code V的m檔。(m files for using Code V in Matlab.)

本实验设计了一个《北京、南京、深圳列车查询系统》的图形用户界面。用户可以通过此界面，采用“按车站名称查询”、“按列车车次查询”和“按出发地—目的地查询”三种方式，方便地查询需要的列车信息。界面友好清新，操作方便。(The experimental design was a " Beijing, Nanjing, Shenzhen Train Enquiry System," the graphical user interface. Users can use this interface, a " query by station name" , " Query by Train Train" and " by origin- destination query" three ways to easily check in need train information. Fresh and friendly interface, easy to operate.)

讲述了最大熵估计的方法，以及dsp的实现方法，比较清楚(spoke of the estimated maximum entropy method, and the realization dsp, more clearly)
