1、OpenCV入门（二）图像的加载Opencv以及VS的相关配置见前面一篇博文。一、加载一张图片#include"stdafx.h"#include"highgui.h"intmain(intargc,char**argv){IplImage*pImg;//声明IplImage指针//载入图像if(argc==2&&(pImg=cvLoadImage(argv[1],1))!=0){cvNamedWindow("Image",1);//创建窗口cvShowImage("Image",pImg);//显示图像cvWaitKey(0);//等待按键cvDestroyWindow("Ima
2、ge");//销毁窗口cvReleaseImage(&pImg);//释放图像return0;}return-1;//此处if做了一个异常处理，如果加载图片不成功，则会出现cmd窗口一闪即消失的情况。}注解：上面是opencv中文论坛的程序。另外一种版本，比较简单，不做判断，直接加载图像。注解：cvLoadImage(filename,-1);默认读取图像的原通道数cvLoadImage(filename,0);强制转化读取图像为灰度图cvLoadImage(filename,1);读取彩色图intmain(intargc,char**argv){ IplImage*img=cvL
3、oadImage(argv[1]); cvNamedWindow("Example1",CV_WINDOW_AUTOSIZE); cvShowImage("Example1",img); cvWaitKey(0); cvReleaseImage(&img); cvDestroyWindow("Example1");}注解：设置命令参数来进行加载。也可以直接加载，不过记住路径是\而不是，程序如下。intmain(){//加载一张图片IplImage*Image1=cvLoadImage("C:\ProgramFiles\OpenCV\samples\test1.jpg",
