视音频课程作业，对视频抽帧，对单张图片进行yuv420采样、DCT变化、量化以及反量化、IDCT变化(Jpeg Encoding & Decoding)

说明：  对流数据的压缩，主要针对二进制的数据代码进行各种长度宽度的压缩。(convection data compression, mainly with regard to the binary code of various length width of the compression.)

对于哈夫曼编码的仿真，可以计算平均码长、熵、压缩比、编码效率(Simulation of Huffman coding)

求解线性矩阵不等式简单方便--与LMI工具箱相比(Solving linear matrix inequalities is simple and convenient- as compared with the LMI toolbox)

对输入的字符进行哈弗曼编码，生成编码表，计算压缩比等(haffman tree)

图像压缩的MATLAB算法之JEPG，完整的例程，参改价值高。(This compression is for jpeg in matlab with a whole example,and it s valuable to look at it!)

说明：  一个用jbuilder做纸牌游戏，希望对你学习有帮助(A card game using jbuilder do, and they hope to help you learn)

压缩包中包含了gl.h，glaux.h，glext.h，glui.h，glut.h等头文件以及对应的库文件。还有对应的配置方法。(Compression package contains gl.h, glaux.h, glext.h, glui.h, glut.h Header Files and corresponding library file. There are corresponding configuration.)

说明：  基于ANN神经网络预测方法，可以较为精确地绘制出预测值与实际值以及误差的曲线(ANN-based neural network prediction method, you can more accurately draw predictive value and the actual value and the error curve)

呃，就是用赫夫曼算法写的压缩解压程序。非常粗糙，只能压缩英文文章。因为里面的字符概率是基于自然语言的，源代码之类的没法压缩。而且会抛弃最后几个字母，嘿嘿。为了交作业，没有好好写。改一下下应该能挺好的。压缩比能到60 吧(Uh, is to use Huffman compression decompression algorithm written procedures. Very rough, only compress English articles. Because there is the probability of characters based on natural language, the source code and the like can not compressed. And will abandon the last few letters, hehe. For homework, not properly written. The following should be able to change it quite good. Compression ratio to 60 of it can be)
