This code implements the concept of content based image retrieval concept using the technique described in The Application of DWT and SVD in Image Retrieval.

说明：  C语言编写的MPG4解码程序，包括完整的解码及编码就结构，适合学习MPG4的相关数据结构及处理流程，(C language MPG4 codec procedures, including a complete decoding and encoding on the structure, MPG4 for learning the structure and the related data processing,)

用VB编的简单cd播放器,实现CD机的基本功能.(VB series with a simple cd player, realize the basic functions of CD drive.)

这是一个音乐读取，时域波形显示（静态），频域频谱（静态），音乐变调，频谱分析的Matlab源程序，纯自己编写！(This is a music reading, time-domain waveform display (static) frequency domain spectrum (static), music modulation, spectral analysis of Matlab source, pure write your own!)

GUI界面设计实现DTMF双音多频电话拨号(GUI design and DTMF source code)

同学写用Java写的 模仿千千静听音乐播放器源代码，界面超漂亮，程序代码简洁，不过程序比较综合，估计没有基础的JAVA朋友不好看懂，想研究一下的可下载试试。编译时需要在Eclipse下打开，并导入源码包目录下的必要库文件才行。(Students to write in Java to write the music player to imitate TTPlayer source code, the interface super-nice, clean code, but more comprehensive program, it is estimated based on JAVA friends did not understand well, to look at the downloadable try. Compile time to open in Eclipse, and import the necessary source package library directory the job.)
