Compresser
- 一种二值图象无损压缩算法 南京理工大学电光学院 【摘 要】利用稀疏矩阵和差分编码对二色图像进行压缩保存，在通过图像的0,1矩阵建立，矩阵一维化，差分量化编码，写文件来压缩。在电子档案存储，CAD制图信息化存储有极高的应用价值。 【关键字】计算机 二值图像 稀疏矩阵 无损压缩 编码 -A binary image lossless compression algorithm for electro-optic Nanjing University of Technology an
A-REMARK-ON-COMPRESSED-SENSING
- 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 (Comp
