香港大学沙威教授写的压缩感知版hello world(Compressed sensing version Hello world written by Professor Javert of University of Hong Kong)

说明：  主要用于图象压缩的库，适合JPEG2000，有损压缩，无损压缩，使用c/c++编译。(The library mainly used for image compression, suitable for JPEG2000, lossy compression, lossless compression, using c/c++ compilation.)

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.)

稀疏贝叶斯学习是一种很好压缩感知，信号恢复方法。(sparse bayesian learning is a good cs method for coefficient recovery.)

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.)

基于哈弗曼树的压缩软件，可压缩文字和位图。(Huffman tree based compression software, compressible text and bitmaps.)

说明：  java对GZIP的压缩格式提供了直接支持，可以方便的实现GZIP压缩与解压(right GZIP compression format provides direct support to facilitate the realization of GZIP Compression and Decompression)

这里给出的源代码huffman.zip用8种不同的方式实现了Huffman编码算法。这些代码意在演示不同Huffman算法的实现原理，比较算法执行效率的差别，但并没有针对实际应用环境的需求，做更多的空空空间或效率优化。全部代码以C++语言开发，为了更容易地实现各种数据结构，代码中大量应用了标准C++库与模板技术。——总之，这些代码的作用在于示例与演示；如果大家想把这些代码应用在实际应用中，可能还需要 (The given here source code huffman.zip eight different ways to achieve the Huffman coding algorithm. These codes are intended to demonstrate different Huffman algorithm implementation principle, the difference of the algorithm execution efficiency, but does not demand for practical application environment, do more empty space or efficiency optimization. The entire code C++ language development code in order to make it easier to achieve a variety of data structures, a large number of applications the standard C++ library template.- In short, these code examples and demonstration If we want the code used in practical applications may also need)
