I am trying to draw a Dot in Bounding Box that will represent the Center Point of that box. I have computed the center Point but it is only outputted in CMD and I wont this Point to be visible on a image.

I am working with OpenCV2.4.3 on Visual Studio 2010 C++

 for(int i= 0; i < boundRect.size(); i++ )
       {
            //BoundingBox Area
            boundingBoxArea.clear();
            boundingBoxArea.push_back(Point2f(boundRect[i].x, boundRect[i].y));
            boundingBoxArea.push_back(Point2f(boundRect[i].x + boundRect[i].width, boundRect[i].y));
            boundingBoxArea.push_back(Point2f(boundRect[i].x + boundRect[i].width, boundRect[i].y + boundRect[i].height));
            boundingBoxArea.push_back(Point2f(boundRect[i].x, boundRect[i].y + boundRect[i].height));

            double area0 = contourArea(boundingBoxArea);

            cout << "area of bounding box no." << i << " = " << area0 << endl;

            //Bounding Box Centroid
            area0 = (boundRect[i].x + boundRect[i].width)/2, (boundRect[i].y + boundRect[i].height)/2;

            cout<<"Rectangle " <<i<< " Centroid possition is at: " "=" <<area0<<endl;
            cout<<""<<endl;
            cout<<""<<endl;
     }

The above is the code that i use well only a small part but a part that is responsible for calculations on Bounding Boxes
