压缩感知中用OMP算法重构视频序列（程序自己写的，能运行）
最近发现网上压缩感知中用OMP算法重构图像的代码很多，但很少有应用OMP算法来重构整个视频序列的，代码是自己写的，希望对初入门压缩感知的有帮助。由于重构时间的原因，程序中只对前8帧进行了重构。

深入浅出mfc（侯捷 简体中文版 附源代码）
《深入浅出MFC》分为四大篇。第一篇提出学习MFC程序设计之前的必要基础，包括Widnows程序的基本观念以及C++的高阶议题。“学前基础”是相当主观的认定，不过，甚于我个人的学习经验以及教学经验，我的挑选应该颇具说服力。第二篇介绍Visual C++整合环境开发工具。本篇只不过是提纲挈领而已，并不企图取代 Visual C++使用手册。然而对于软件使用的老手，此篇或已足以让您掌握Visual C++整合环境。工具的使用虽然谈不上学问，但在视觉化软件开发过程中扮演极重角色，切莫小觑它。 第三篇介绍application framework的观念，以及MFC骨干程序，所谓骨干程序，是指Visua
