示例代码：

#include<opencv2/core/core.hpp>#include <opencv2/imgproc/imgproc.hpp>#include <opencv2/highgui/highgui.hpp>#include <opencv2/video/background_segm.hpp>#include <time.h>#include <Windows.h>#include <iostream>using namespace std;using namespace cv;int main(){VideoCapture capture("E:/图片/bike.avi");if (!capture.isOpened())return 0;Mat frame; Mat foreground;namedWindow("Extracted Foreground");BackgroundSubtractorMOG mog;bool stop(false);int i = 0;while (!stop) {if (!capture.read(frame))break;mog(frame,foreground,0.01);threshold(foreground,foreground,128,255,THRESH_BINARY_INV);/*变量的定义*/char image_name[13];sprintf(image_name, "%s%d%s", "image", ++i, ".jpg");//保存的图片名imwrite( image_name, foreground);   //保存一帧图片//imshow("Extracted Foreground",foreground);if (waitKey(10)>=0)stop= true;}waitKey();}

运行结果：
