This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.

G729编码和解码的Matlab源程序 调用方法： 1.需要编码时，在 Matlab命令行下输入"G729code(speech)"(请务必保证 speech是已经存在在 Matlab工作区的一个行向量，其中是语音数据)，然后你会在你的文件夹下看到一个"coding.bit"的文件。 2.需要解码时，把"coding.bit"的文件复制到"G729 decoder"的目录下，在Matlab命令行下输入"G729decodermain"，然后你会在文件夹下看到"syn_speech.wav"，那就是重构语音。 enjoy it!

电话拨号音的合成与识别 基于对电话通信系统中拨号音合成与识别的仿真实现，主要涉及到电话拨号音合成的基本原理及识别的主要方法，利用 MATLAB 软件以及 FFT 算法实现对电话通信系统中拨号音的合成与识别。并进一步利用 MATLAB 中的图形用户界面 GUI 制作简单直观的模拟界面。使其对电话通信系统拨号音的合成与识别有个基本的了解。 能够利用矩阵不同的基频合成 0 － 9 不同按键的拨号音，并能够对不同的拨号音加以正确的识别，实现由拨号音解析出电话号码的过程。(Synthesis and recognition telephone dial tone Based on telephone communication system dial tone Simulation synthesis and recognition, mainly related to the basic principles of the main methods telephone dial tone synthesis and recognition, using MATLAB software and the FFT algorithm for synthesis and recognition telephone communication system dial tone. And further use of MATLAB graphical user interface is simple and intuitive GUI making analog interface. Synthesis and recognition make telephone communication system dial tone have a basic understanding. Can be different the fundamental frequency of matrix synthesis 0 9 dial tone different keys, and can be correctly identify different dial tone, dial tone achieved by the parsed telephone number of processes.)
