本程序分两部分，分别为界面和驱动程序，其中驱动程序为压缩解压缩的核心程序。 开发环境为VC6.0。 界面部分可由crs->ddu->ddu.dsp建立工作组，编译生成的可执行程序为debug中的ddu.exe 驱动部分由crs->驱动->驱动.c编译生成可执行文件。 具体压缩解压缩操作可见《操作手册》。-This procedure was divided into two parts, namely, interface and driver, one of the drivers for the compression of the core decompression procedure. Development environment for VC6.0. Interface may be part of crs->ddu-> ddu.dsp Working Group set up, the compiler generates the executable program to debug the ddu.exe driven in part by crs-> Driver-> Driver. C compiler to generate executable file. Extract specific compression operation can be seen " manual."

基于小波的图像压缩，可运行，基于实数小波和EZW编码-Wavelet-based image compression can be run, based on real wavelet and EZW coding

【文本与二值图像的游程】1. 文本游程压缩的原理 对重复字段采用3符号标识法：(1) 重复提示符,比如@,#等；(2) 游程长度参数或重复次数,若用一个字节表示,最大长度可为255个重复字；(3) 重复字符。以上三部分合称为重复因子。可见要获得压缩效益，重复字符应在3个以上。2. 图像游程压缩的原理 对于二值图像，原始数据为零一矩阵，压缩时逐行处理该矩阵：(1) 连续n个1，表示为+n；(2) 连续n个0，表示为-n。-text and binary image-- an outbound trip. Yu Cheng text compression principle on repeated field using three symbols logo Act : (a) repeat prompt, such as @,#, etc.; (2) Run-length parameters, or the number of repeat, if using a byte, the largest the length of 255 to repeat the word; (3) repeat characters. More than three as part of a repeat factor. Visibility to gain compression efficiency, duplication of characters in three more. 2. Run-image compression for the principle of two binary images, a zero original data matrix, progressive compression deal with the matrix : (1) n a row, n; (2) consecutive n 0, expressed as-n.
