title: How to use machine learning to detect one simple objects
body: <p>I am trying to detect circles / ellipses in the image.</p>

  <p>The HoughCircle method doesn't work, because these are more eliptic then circle. 
  Do you have any ideas how to find the "circles"?</p>
  
  <p>Maybe some machine learning method? Like SVM? Because I can create the training dataset which will contains many of these shapes.</p>

  <p>Thank you very much for your ideas.</p>
