【实例简介】最近用到人脸识别技术，有个需求是多人脸图片的时候需要一个一个把人脸裁剪出来，以便获取人脸的图片，从而用其获取单人脸的特征

《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
