采用离散小波变换方法(Mallat算法)，实现对语音信号的双通道子带压缩编码。将语音信号中，C125Hz的低频区信号完全保留，在125Hz飞KHz频段的语音信号用小波分解逐级进行较为精确的量化并进行滤波，而将高频部分采用游程编，进而达到在保证语音信号原有特性的前提下大幅度的压缩语音信号的传输数据量

改进后的游程编码，可以继续量化编码转化为二进制数据流，针对一些较为接近的数，通过合适的阈值设定可以近似，从而大大压缩数据流-The improved run-length coding, can continue to quantify the code into binary data stream, for some of the more close to the number set by appropriate threshold can be approximated, thereb

利用游程编码和哈弗曼编码实现灰色图片的压缩和解码，压缩比可达15倍-Using run-length encoding and Hafu Man Coding and decoding of gray image compression, the compression ratio up to 15 times

低比特图像压缩的 matlab实现，主要是游程编码-Matlab low bit image compression to achieve, mainly RLE

游程编码是一种简单的非破坏性资料压缩法，其好处是加压缩和解压缩都非常快。-RLE is a simple non-destructive data compression method, the added advantage of very fast compression and decompression. The method is to calculate the length of consecutive compression of the data.
