matlab写的lzw和huffman的编码

%基于lzw编码的应用实例
tu=imread('11.jpg');
tu2=double(tu(:,:,1)); %转化为只有8位的像素矩阵
tu2=tu2>=128;
size2=size(tu2);
code=lzwcode2(tu2)
tu3=lzwdecode2(code,size2);
figure(1);
subplot(2,2,1),imshow(tu(:,:,1))
title('原图');
subplot(2,2,2),imshow(tu2)
title('lzw压缩二值图像');
subplot(2,2,3),imshow(tu3)
title('lzw解码后二值图像');
