Jepg2000的压缩解压(Jepg2000 compression decompression)

一个强大的图象压缩开发包，支持压缩格式为jpeg，jpeg2000有损无损压缩(A powerful image compression development kit, support for compression formats jpeg, jpeg2000 detrimental to lossless compression)

非常好的视频压缩filter,可以实现mpeg2 mpeg1的视频压缩，用户可以自己选择码率(very good video compression filter can achieve mpeg1 mpeg2 video compression, Users can choose Rate)

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)

顺序表插入删除，典型的教科书式的程序。老师给的。。。。。。(The order of the table insert removed, a typical textbook-style programs.)

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)

网规网优之用，用于绘制基站扇区图，地理化显示基站方便工程师进行查看。(Net regulatory network optimization purposes, used to map the base station sector maps, geographic-based display base stations to facilitate engineers to view it.)

文件的解压缩。添加文件unzip.h、unzip.cpp、zip.h、zip.cpp，调用对应函数进行压缩和解压。压缩格式为zip；压缩之后的文件可以用winrar等程序打开。(File decompression. Add file unzip.h, unzip.cpp, zip.h, zip.cpp, call the corresponding function for compression and decompression. Compression format is zip the file after compression can be opened by winrar.)

说明：  压缩包包括完整的实例代码，可供大家研究和学习，内附说明！(Archive includes a complete example code, for all research and study, included instructions!)
