前几天看到有人在论坛上寻找压缩代码，自己前几天又不是很忙，就摸索着写了这个程序-saw a few days ago was at the Forum for compression code, a few days before his is not so busy, writing on the exploration of this process

运用java开发工具，java 本身具有的类库的优势，应用java 提供的有关方法实现基本的压缩和解压缩功能。-use java development tools, java itself with the library"s strengths, java application of the method for the realization of basic compression functions.

本程序采用了最简单的方块编码对512×512的lena图像进行了编码.运行程序后可以看出，方块取得越大，图像编码后失真越大。-This procedure uses the most simple code box 512 × 512 on the lena image coding. After running the program we can see that the box to obtain the greater the greater the distortion image is encoded.

【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.
