本程序用matlab编写。实现图像的构造编码。压缩包中的PPT介绍构造编码。一个编码程序,一个解码程序。本程序是无损压缩,编码后可压缩掉30 以上。附有图片。程序有必要的注释。(This program written by matlab. The structure of image coding. PPT introduced compressed package structure encoding. A coding process, a decoding program. This procedure is lossless compression, encoding more than 30 after the compressible out. With pictures. Program has the necessary comments.)

EEMD程序
%(第一步加载原始数据并绘图)m文件保存代码;而mat文件保存工作区里面已经加载或计算好的数据
%当前文件夹显示的路径一定要是保存数据和保存代码的文件夹
%“relt”是包含分解结果的矩阵,第一列是原始输入(“gsta(:,2)”),最后一列是趋势。 中间是IMF频率从高到低。
%应该注意的是,由于在eemd.m中,IMF的总数m被指定为log2(N)-1,在某些情况解的线条进行了合并
%因此会比实际分解得到的减少,但在计算周期和表现显著性的时候要将每个模态的周期和显著性计算在内。((The first step is to load the original data and draw) m file saves the code; the mat file saves the data already loaded or calculated in the workspace %% the current folder displays a path that must store data and save the code folder. %"relt" is the matrix that contains the decomposition result, the first column is the original input ("gsta (:, 2)"), and the last column is the trend. The middle is the IMF frequency from high to low. It should be noted that since the total number m of IMFs in eemd. m is specified as log2 (N) - 1, the lines of the solution are merged in some cases % will therefore be less than the actual decomposition, but the period and salience of each mode will be taken into account when calculating the period and performance saliency.)
