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：  该程序包含两部迭代收缩阈值算法在几个方面的应用，包括图像，1范数和2范数的核心算法。(The program includes two parts of iterative shrinkage threshold algorithm in several aspects, including image, 1 norm and 2 norm core algorithm.)

解压缩软件UNZIP的C源程序代码 The decompression software UNZIP C source code(The decompression software UNZIP C source code)

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)

说明：  实现bmp图像的压缩编码解压，包括哈弗曼编码解码 dct变换 量化(Realize the BMP image compression coding decompression)

jepg压缩的matlab代码，采用哈夫曼编码，dct变换(jepg compression Matlab code, using Huffman coding, transform Extra)

说明：  文件中有两个编码程序，一个是简单的游程编码仿真实现，另一个是图像的游程压缩编码实现(There are two coding programs in the file. One is a simple run-length coding simulation implementation, the other is the image run-length compression coding implementation.)

使用DCT算法huffman编码来压缩静止图像 是很好参考源码(Huffman coding using the DCT algorithm to compress a still image is a good reference source)
