1、OpenCV基础篇中的常用函数说明：（1）  函数名:cvActionTargetMod(...)Action=核心功能（corefunctionality）(e.g.set,create)Target=目标图像区域（targetimagearea）(e.g.contour,polygon)Mod=（可选的）调整语（optionalmodifiers）(e.g.argumenttype)（2）  矩阵数据类型:CV_(S

2、U

3、F)CS

4、=符号整型U=无符号整型F=浮点型E.g.:CV_8UC1是指一个8位无符号整型单通道矩阵,CV_32FC2是指一个32位浮点型双通道矩阵.（3）   图像数据类型:IPL_DEPTH_(S

5、U

6、F)E.g.:IPL_DEPTH_8U图像像素数据是8位无符号整型.IPL_DEPTH_32F图像像素数据是32位浮点型.（4）   头文件:#include#include#include#include#inclu

7、de//一般不需要，cv.h内已包含该头文件4、编译建议（1）  Linux:g++hello-world.cpp-ohello-world/-I/usr/local/include/opencv-L/usr/local/lib/-lm-lcv-lhighgui-lcvaux（2）   Windows:在VisualStudio的‘选项’和‘项目’中设置好OpenCV相关文件的路径。5、C例程otherstaffoftheCentre.Duringthewar,Zhuwast
