bnpts点云文件 进过压缩处理 大约100000个点(bnpts)

说明：  实现了图像的哈夫曼编码和解码，对图像编码的学习很有帮助(Achieved image Huffman encoding and decoding of image coding learning helpful)

solver PMD (optical fiber)

说明：  一篇关于压缩感知的经典文章，压缩感知（Compressed sensing，简称CS，也称为Compressive sampling)理论异于近代奈奎斯特采样定理，它指出：利用随机观测矩阵可以把一个稀疏或可压缩的高维信号投影到低维空间上，然后再利用这些少量的投影通过解一个优化问题就可以以高概率重构原始稀疏信号，并且证明了这样的随机投影包含了原始稀疏信号的足够信息。(A classic article on compressed sensing, compressive sensing (Compressed sensing, referred to as CS, also known as Compressive sampling) different from the modern theory of the Nyquist sampling theorem, which states: the use of a random measurement matrix can be sparse or compressible high-dimensional signal projected to low dimensional space, and then use a small amount of projection by solving an optimization problem to be sparse with high probability to reconstruct the original signal, and prove that random projection of the original sparse signal contains enough information.)

基于类函数形函数的参数化建模方法，适用于气动设计和优化(Class/Shpae Transform method)

MATLAB code for image forgery detection

这是一个基于LZARI算法的数据压缩的类.Haruhiko Okumura 于1989年7月4日用C语言写实现了这个算法.但是上面用到了一些全局或静态的变量,在MFC下用起来很不方便.作者把它改写成了一个C++类,使它可以方便的压缩和解压缩。(LZARI algorithm based on the type of data compression. Haruhiko SAP in 1989, July 4 C language daily wrote realization of this algorithm. But above uses some static or global variables, using the MFC which are very convenient. Authors rewrite it became a category C, it can be to facilitate the compression.)

利用Huffman编码方式对一段文字进行编码和解码。哈夫曼编码是可变字长编码(VLC)的一种。(Using the Huffman encoding method for encoding and decoding of a paragraph of text. Huffman code is a variable length coding (VLC) is a kind of.)

在分布式压缩感知中的一种重构算法，联合向前正交追踪算法。(In a distributed compressed sensing reconstruction algorithm, combined forward orthogonal tracking algorithms.)
