Basically grabCut return a black n white image. How can I take the limit values of the whites which corresponds to foreground?

I am using hogpedestrians cascade in order to calculate body in an image. I want to implement grabCut algorithm in order to restrict bounding box using grabCut implementation. I am using the following code:

        // GrabCut segmentation
        cv::grabCut(image,    // input image
            result,   // segmentation result
            BBox.at(0),// rectangle containing foreground  of body detector
            bgModel,fgModel, // models
            10,        // number of iterations
            cv::GC_INIT_WITH_RECT); // use rectangle
        // Get the pixels marked as likely foreground
        cv::compare(result,cv::GC_PR_FGD,result,cv::CMP_EQ);

The result of the grabcut segmentation is foreground and background pixels. How can I restrict my initial bounding box calculated with cascades using the result of grabCut? EDIT: the result of grabcut is result mat which contains the foreground pixels and the background pixels are black. How can I take the bounding box of the foreground pixels using result Mat file?

Ok I got it. However is there any implementation in which I can get the body using grabCut? I mean something like that http://docs.opencv.org/3.0-beta/doc/p...

Yes sometimes the body does not take straightforward poses. Therefore it is not the best idea to calculate the boundingbox using the face. I want to calculate the boundingbox using grabcut and the face as input to grabCut algorithm.

I want to create a body detection software for images using grabCut opencv c++ implementation. I have already the position of faces in the images. Therefore I want to use the information of image in order to caluclate the body bounding box using grabCut (in order to calculate the foreground). I am using the following imgproc implemenation of grabCut algorithm:

    cv::grabCut(image,    // input image
        result,   // segmentation result
        faces.at(0),// rectangle containing foreground 
        bgModel,fgModel, // models
        5,        // number of iterations
        cv::GC_INIT_WITH_RECT); // use rectangle

Where faces.at(0) the first face in the image. The result mask contain only area near the face. How can I get the whole containing area of the foreground( my body in that case)?
