title: How to get extra information of blobs with SimpleBlobDetector?
body: <p>@robot_sherrick answered me <a href="https://stackoverflow.com/a/13534094/1705967">this question</a>, this is a follow-up question for his answer.</p>
  
  <p><code>cv::SimpleBlobDetector</code> in Opencv 2.4 looks very exciting but I am not sure I can make it work for more detailed data extraction. </p>
  
  <p>I have the following concerns: </p>
  
  <ul>
  <li>if this only returns center of the blob, I can't have an entire, labelled Mat, can I? </li>
  <li>how can I access the features of the detected blobs like area, convexity, color and so on?</li>
  <li>can I display an exact segmentation with this? (like with say, waterfall)</li>
  </ul>
