Description: This file contains a new and improved version of the Huffman coder, (June 29. 2001). The name is Huff06.m. There are also some additional files which are helpful when using Matlab for data compression: quantizer, different variants of run-length-encoding and end-of-block coding in Mat2Vec, and a program which do JPEG-like entropy coding. A complete compression example is shown in TestMat2Vec.m. This file is all you need for Huffman coding in MatLab.-This file contains a new and improved version of on of the Huffman coder, (June 29. 2001). The name is Huff06.m.

Description: 离散余弦变换对图象信号有近似最优的去相关能力, 但多维的变换公式一直没有给出. 为此深入研究了
三维离散余弦变换, 提出了任意尺寸的三维函数f (x , y , z ) 的正交离散余弦变换公式, 克服了以前系数的取值必须
相等的缺点, 并将之应用于彩色静止图象的压缩编码中, 使得彩色图象的R、G、B 3 帧可以作为一个整体同时进行
变换, 极大地去除了图象R, G,B 3 帧间的相关性. 理论分析和实验结果表明, 在大幅度地增加压缩比的同时, 峰峰
信噪比也有明显提高, 并且与国际标准JPEG,M PEG 有很好的兼容性.-hao
