Simulink TDSD system

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.

使用matlab编写的各种类型的遗传算法，每一种都有注释说明 可以复制到M文件中运行(Matlab prepared using various types of genetic algorithms, each with explanatory notes can be copied to M to run in files)

说明：  用遗传算法解决tsp问题，matlab程序，很好很有用哦(algorithm for multi- objective optimization. It is a very e&reg ective algorithm but has been generally criticized for its computational complexity,)

说明：  雷达信号处理与电子战对抗实验中的干涉仪测向实验，matlab GUI编程全部源码(Radar signal processing and interferometer direction finding experiment in electronic warfare confrontation experiment, matlab GUI programming all source code)

用matlab浏览raw文件。matlab6.5下运行(View raw file using matlab. matlab6.5 run)

Toolbox for wavelet transform computation

介绍了一种基于MATLAB的多个特定人连接词语音识别的方法，并提出了在进行端点检测时，引入平均的概念能进一步提高识别率。此设计是以LPCC系数、DTW算法为核心的基于图形界面的设计。(A Based on MATLAB more specific conjunctions speech recognition, and during endpoint detection, the introduction of the concept of average to further improve the recognition rate. This design is based on LPCC coefficients, the DTW algorithm as the core-based graphical interface design.)
