Alternative of bg.set function in opencv 3

Question

I am getting an error when I am trying to execute the below-mentioned code of line by using OpenCV 3 version.

bg.set("nmixtures", 10);

Error bg object does not have any member name .set

Can anybody tell me how to use the same function in OpenCV 3 version

How was bg created?, you should add the code necessary to reproduce the error. This way you may get a faster and better answer. — api55, Feb 12 '19 at 13:35

The right way:

cv::BackgroundSubtractorMOG2* bgsegm = bg.dynamicCast<cv::BackgroundSubtractorMOG2>();
    if (bgsegm)
    {
            bgsegm->setNMixtures(10);
    }
