title: Ellipse detection with OpenCV
body: <p>I would like to detect ellipses with OpenCV for Android, using the Tutorial 2-Basic included with OpenCV 2.4.1 package as a starting point. Note that my ellipse would be a perfect-photoshop one.</p>
  
  <p>From what I understand, using the "HoughCircles" will only find perfect (or so) circles, thus leaving ellipses out.</p>
  
  <p>Any help would be much appreciated as I am a total beginner at OpenCV</p>
  
  <p>This is what I've tried so far</p>
  
  <pre><code>    case Sample2NativeCamera.VIEW_MODE_CANNY: (ignore the Canny mode...)
  
          capture.retrieve(mGray, Highgui.CV_CAP_ANDROID_GREY_FRAME);
          Imgproc.HoughCircles(mGray, mCircles, Imgproc.CV_HOUGH_GRADIENT, 1, 20);
          Log.d("Ellipse Points", " X " + mCircles.get(1,1)[0] + mCircles.get(1, 1)[1]);
  
          break;
  </code></pre>
  
  <p>If you think any more info could be useful, please let me know.</p>
