title: OpenCV python's API: FlannBasedMatcher
body: <p>I am trying to rewrite the code described <a href="http://opencv.itseez.com/doc/tutorials/features2d/feature_homography/feature_homography.html#feature-homography">here</a>. using the python API for Opencv.</p>
  
  <p>The step 3 of the code has this lines:</p>
  
  <pre><code> FlannBasedMatcher matcher;
   std::vector&lt; DMatch &gt; matches;
   matcher.match( descriptors_object, descriptors_scene, matches );
  </code></pre>
  
  <p>I have looked over and over in <a href="http://opencv.itseez.com/index.html">the OpenCV reference</a> but found nothing related to a FlannBasedMatcher in python or some other object which can do the work.</p>
  
  <p>Any ideas?</p>
  
  <p>NOTE: I am usign OpenCV 2.3.1 and Python 2.6</p>
