RGB-CMYK by matlab sourcecode

bnpts点云文件 进过压缩处理 大约100000个点(bnpts)

图像JPEG压缩算法，由8*8DCT变换，调用量化表进行量化，最后由Huffman编码完成算法(JPEG image compression algorithm, the 8* 8DCT transform, quantization table calls to quantify, and finally completed by the Huffman coding algorithm)

bmp转换为jpeg,jpeg压缩的源代码 程序用vc实现了bmp图片转换成jpeg图片(converted to jpeg bmp, jpeg compression source code procedures used vc realized bmp images converted into jpeg photos)

霍夫曼编码，这是信息论方面很重要的一种编码方式，对学习信息论理论的人很重要！(Huffman code)

 用霍夫曼编码实现的简单的文本压缩解压缩C++源程序

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.)

算术编码，利用算术编码进行数据压缩，用C语言实现，程序简单，已跑通(Arithmetic coding, the use of arithmetic coding for data compression, using C language, the procedure is simple, has run through)
