In BackgroundSubtractorMOG2 set background fixed(static) like BackgroundSubtractorMOG

Is there any way to fix the background set in BackgroundSubtractorMOG2 as in BackgroundSubtractorMOG.

heres my code to detect hand ... It does not have a fixed background

include<opencv2 opencv.hpp="">

include<iostream>

include<vector>

using namespace cv;

using namespace std;

const int nmixtures=10;

const bool shadow=false;

const int history =1000;

BackgroundSubtractorMOG2 back_obj(history,nmixtures,shadow); //BackgroundSubtractorMOG back_obj; this gives me a first frame as fixed background.

int main(int argc,char **argv)

Mat original;

Mat background,foreground;

VideoCapture cap(0);

std::vector<std::vector<cv::Point> >contours;

namedWindow("ORIGINAL");

namedWindow("BACKGROUND");

namedWindow("FOREGROUND");

while(1)

    {


cap>>original;





back_obj.operator()(original,foreground);


    back_obj.getBackgroundImage(background);





erode(foreground,foreground,Mat());     

dilate(foreground,foreground,Mat());        


findContours(foreground,contours,CV_RETR_EXTERNAL,CV_CHAIN_APPROX_NONE);


drawContours(original,contours,-1,Scalar(255,255,0),4);


imshow("ORIGINAL",original);

imshow("BACKGROUND",background);

imshow("FOREGROUND",foreground);




if(waitKey(10)>=0)

    {

    break;

    }
}

return 0;

}
