title: create a window opencv
body: <p>Happy new year.</p>
  
  <p>I'm working on a project which I want to do now is to make a big black window and in order to put in the middle the capturing video. I have captured the video already with its window and now I want to create a new window but bigger than the first one and I want to put in the middle of this window the captured frame video. </p>
  
  <p>Now my problem is that I'm getting the same size of the first window that I made which I want a window has bigger size than the captured frame, so let's suppose a captured a frame and around it a black space. My aim is to make a new one which is bigger and the background is black and in the middle the captured frame?</p>
  
  <p>This is what I'm doing, here is the code</p>
  
  <pre><code>    cvNamedWindow("stabilized image", CV_WINDOW_AUTOSIZE );
      IplImage* image = cvCreateImage(cvSize(900,650),IPL_DEPTH_8U,3);
  
      cvZero( image );
      image=cvCloneImage(frame);
  
      cvShowImage("stabilized image", image );
  </code></pre>
