DCT
- 首先对图像进行离散余弦变换,在进行量化,编码,最终输出压缩图像-Firstly, the image discrete cosine transform, quantization during encoding, the final output compressed image

- 这代码非常好,一定会对你有所帮助。实用性方面也不错,希望好好学习。-verry good.you can get a lot that everything can help you
Jsteg
- Jsteg算法实现,Jsteg是一种基于JPEG的常用信息隐藏算法步骤如下: 首先,把掩体图像分为不重叠的8*8的子块,对每一子块进行DCT并对变换得到的DCT系数进行量化 其次,将待隐藏的信息进行加密,将加密结果嵌入到量化后值不为0,1或-1的DCT系数的最 低有效位(LSB)中,其嵌入顺序是按zigzag扫描顺序进行的。最后,用JPEG的嫡编码(包括哈夫曼编码,游程编码及DPCM)对嵌入秘密信息后的每一子块进行编码,从而得到一个含有秘密信息的JPEG stego文件。-Jsteg
FTPClient

TestBp2
- 一个用来把几个文件打包成一个文件的程序, 挺好用的。-Used to pack a few files into one file program, very good use.
cdpress
- Static length frequent matching compression for cache data in simple scalar
HFMHFM
- 通过哈夫曼树,构造最优树,减小编码长度并压缩,达到压缩解压缩的功能-By Huffman tree, the optimal structure of the tree, reducing the length and compression coding to achieve compression and decompression functions
packJPG-v2.5
- JPG图像压缩工具:PackJPG。PackJPG是一个命令行界面的程序,没有GUI界面,但是不要输入命令也能使用。只要直接将要压缩的图片拖放到PackJPG.exe上,程序 就会自 动开始压缩了。压缩生成的格式为pjg,为其专有格式。需要解压缩时,将pjg文件拖放到PackJPG.exe就自动开始解压缩。-packJPG v2.5
sampletest
- 基于零数小波算法的的图像压缩(小波变换)-Based on zero wavelet image compression
matlab-code
- 本代码可去除照片的模糊,让照片变的清晰,内服MATLAB程序及图片-This code can remove the image of the blur, so that the picture becomes clear, internal MATLAB procedures and pictures
salary_4.3.2
- 本asp程序是基于Excel文件的工资条查询系统,对excel文件要求很低,考虑到会计发工资时一般都用Excel电子表格.-This ASP program is based on the Excel file of the wage query system, the excel file is very low, considering the accounting wages are generally used Excel spreadsheet.
tbszip_a5
- TbsZip是一个PHP的类用来读写Zip压缩文件包,该类无需PHP扩展或者是临时文件。TbsZip可以对压缩文档中的文件进行读、写、修改和删除操作。- Tbszip is a PHP class which can read a zip archive,and even edit sub-files in the archive and then create a new archive.
