Description: 一张图片是之前用摄像机采集的，另一张图片是经过离散沃尔什变换再量化编码压缩后又解压所得，能看出区别吗？呵呵。flik.m是原图，newflik.m是新图。
附上所有MATLAB源程序，有兴趣的话，你也可以用这几个程序对自己的照片“加工”一番。以下6个程序分别保存为6的m文件，文件名与下面给出的一致。待“加工”图片应该存放在Matlab的Work目录下。-Before a picture is collected by the camera, another picture is the result of discrete Walsh transform and then re-quantization coding compression decompression income, you can see the difference? Ha ha. flik.m is the image, newflik.m is a new map. MATLAB source code attached to all interested, you can also use these procedures on their own photo processing of something. The following six procedures were saved as 6 m file, the file name is given with the following consensus. To be processing picture should be stored in Matlab s Work directory. Platform: |

Description: 一个分形压缩的程序：
1、因为本程序时间长，FX中先选择图片的大小
2、编码与解码
3、做误差图和只方图
4：画出每次迭代的解码图象
5、本程序来自本网站，修改了部分，解释说明更清楚。
6、增加了部分功能，希望对大家有所帮助，互相学习……
-A fractal compression process: 1, because this process a long time, FX in the first select the size of picture 2, encoding and decoding 3, so the error map and the only side Figure 4: Draw the image of each iteration of the decoder 5, This procedure from this site, modify the part, more clearly explained. 6, an increase of some functions, I hope all of you to help and learn from each other ... ...

Description: 解压后将myfiest.fig，myfirst.m，Run_Draw.m放在同一个目录下，用matlab打开即可学习。
其中myfiest.fig是设计的GUI图形界面，myfirst.m是该图像界面的m文件，Run_Draw.m是该源文件中用到的一个绘图函数。
myfirst.m中给出了详细的注释，利用此例子可以快速入门matlabGUI编程。
有任何问题请联系：peiwt@126.com-After decompression myfiest.fig, myfirst.m, Run_Draw.m on the same directory, you can learn to use matlab to open. Myfiest.fig which is the graphical interface GUI design, myfirst.m is the image of m document interface, Run_Draw.m the source files used in a mapping function. myfirst.m given detailed notes, using the examples matlabGUI Quick Start program.
