Huffman

实现图像的jpeg无损压缩，可以在linux系统下经过交叉编译器编译后在arm上实现，已经写好makefile文件(Realize jpeg image lossless compression, you can linux system through cross-compiler to compile in the arm to achieve, has written makefile file)

文件的解压缩。添加文件unzip.h、unzip.cpp、zip.h、zip.cpp，调用对应函数进行压缩和解压。压缩格式为zip；压缩之后的文件可以用winrar等程序打开。(File decompression. Add file unzip.h, unzip.cpp, zip.h, zip.cpp, call the corresponding function for compression and decompression. Compression format is zip the file after compression can be opened by winrar.)

用于对图像的huffman编解码,创建了图像界面,按照提示操作(Huffman codec used on the image to create a graphical interface, follow the prompts)

说明：  一个简单的32位位图压缩算法，基本思想是，扫描像素点，后面有雷同的就记下重复次数。(A simple 32-bit bitmap compression algorithm, the basic idea is to scan pixel, behind identical repetitions on the record.)

基于哈弗曼树的压缩软件，可压缩文字和位图。(Huffman tree based compression software, compressible text and bitmaps.)

赫夫曼编/译码器源码，已生成的每个字符的赫夫曼编码，对任意字符文本进行编码，再译码(Huffman encoder/decoder source code, Huffman coding, each character has been generated, the text of any character encoding, decoding)

说明：  一个上课很好用的课件，是您编程的很好帮手(why)
