vc2003与vc6.0区别?
代码如下：
int _tmain(int argc, _TCHAR* argv[])三帧差 vc6.0 vc2003
{//声明IplImage指针
IplImage* pFrame = NULL;
//三帧图像
IplImage* pFrame1 = NULL;

//三帧图像相减图像
IplImage* pFrImg1 = NULL;
IplImage* pFrImg2 = NULL;
//最终图像
IplImage* pFrImg = NULL;
//视频图像
CvCapture* pCapture = NULL;
//帧数
int nFrmNum = 0;
//创建窗口
cvNamedWindow("video", 1);//视频
/*cvNamedWindow("background",1);*/
cvNamedWindow("foreground",1);
//使窗口有序排列

}
//逐帧读取视频

{
