说明：  本文档包括了OpenCV2.2版（2010年12月推出，目前最新版）中所有API函数的说明，包括C、C++、Python中调用OpenCV的所有接口函数，是大家开发计算机视觉、图像处理、模式识别程序的好参考。OpenCV2.2提供了支持Visual Studio 2010的可执行版本，并且添加了HOG行人检测器，真是不可多得的好东西。
(This document includes OpenCV2.2 edition (December 2010 launch, the latest version) a description of all API functions, including C, C++, Python OpenCV call all the interface functions, there is little development of computer vision, image processing, pattern a good reference for identification procedures. OpenCV2.2 supported executable version of Visual Studio 2010 and added the HOG pedestrian detector is really a rare good thing.)
