Getting started with OpenCV

首先，你得设置编译环境(针对Visual C++)，包括：

1.添加含“头文件”的文件夹位置，
<OPENCV_INSTALL>/cv/inlcude
<OPENCV_INSTALL>/cxcore/include
<OPENCV_INSTALL>/cvaux/include
<OPENCV_INSTALL>/otherlibs/cvcam/include
<OPENCV_INSTALL>/otherlibs/highgui

2.添加库文件所在的文件夹位置，
<OPENCV_INSTALL>/lib

3.和含有源文件的文件夹位置。
<OPENCV_INSTALL>/cv/src
<OPENCV_INSTALL>/cxcore/src
<OPENCV_INSTALL>/cvaux/src
<OPENCV_INSTALL>/otherlibs/highgui
<OPENCV_INSTALL>/otherlibs/cvcam/src/windows

*<OPENCV_INSTALL>即是OpenCV的安装位置。

然后建立一个工程，添加如下代码：

#include "stdafx.h"
#include <cv.h>
#include <cxcore.h>
#include <highgui.h>

int main(int argc, char **argv)
{
    IplImage *img = cvLoadImage("Image.bmp");
    cvNamedWindow("Image:", 1);
    cvShowImage("Image:", img);

    cvWaitKey();
    cvDestroyWindow("Image:");
    cvReleaseImage(&img);

    return 0;
}

当然别忘了添加编译所需的.lib文件(cxcore.lib cv.lib highgui.lib cvaux.lib)，不然链接器会显示无法链接函数。然后编译，运行。
