title: How to check contours whether they are ellipse or not by using fitEllipse function in OpenCv C++?
body: <pre><code>    vector&lt;vector&lt;Point&gt; &gt; contours;
      vector&lt;Vec4i&gt; hierarchy;
  
      findContours(img, contours, hierarchy, CV_RETR_TREE, CV_CHAIN_APPROX_SIMPLE, Point(0, 0));
  </code></pre>
  
  <p><em>Now how can i get the location of ellipses from these contours??</em> </p>
