执行到这句话，就over了，原因不明 mog->apply(frame, foreground);

楼主，，你后来解决了这个问题没？我今天遇到了同样的问题

你从哪里抄来的程序代码？？BackgroundSubtractorMOG2这个是什么类型的？在哪里声明了？

mog(frame, foreground, 0.001);
// 腐蚀 cv::erode(foreground, foreground, cv::Mat());
// 膨胀 cv::dilate(foreground, foreground, cv::Mat());
mog.getBackgroundImage(background); // 返回当前背景图像
cv::imshow("video", foreground);
cv::imshow("background", background);
if (cv::waitKey(25) > 0) {
break; } }
return 0;}

我这个没有提示那样问题呢 只不过打不开视频怎么回事？

打开文件需要自己的。。。

碰到相同问题

一模一样的问题，请问楼主解决了么
