我试图通过OpenCV.org这个教程:

http://docs.opencv.org/trunk/doc/tutorials/video/background_subtraction/background_subtraction.html#background-subtraction

MOG指针初始化为

Ptr<BackgroundSubtractor> pMOG; //MOG Background subtractor

在主要情况下,它以下列方式使用:

pMOG = createBackgroundSubtractorMOG();

但是,这会产生以下错误:

    Error: Identifier "createBackgroundSubtractorMOG" is undefined

此外,要更新背景模型时,使用以下命令:

pMOG->apply(frame, fgMaskMOG);

这又会产生以下错误:

    Error: class "cv::BackgroundSubtractor" has no member "apply"

知道可以做些什么吗？提前谢谢了!

这是整个教程代码:

//opencv
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/video/background_segm.hpp>
//C
#include <stdio.h>
//C++
#include <iostream>
#include <sstream>

using namespace cv;
using namespace std;

//global variables
Mat frame; //current frame
Mat fgMaskMOG; //fg mask generated by MOG method
Mat fgMaskMOG2; //fg mask fg mask generated by MOG2 method
Ptr<BackgroundSubtractor> pMOG; //MOG Background subtractor
Ptr<BackgroundSubtractor> …
