title: How to use Shape Distance and Common Interfaces to find Hausdorff Distance in Opencv?
body: <p>I would like to find Hausdorff Distance between two Canny detector output image which contains group of contours, to find the similarity of two Shapes. For that i need to Find Hausdorff Distance Estimation. Does Opencv has this function implemented in it?
  I've found <a href="http://docs.opencv.org/trunk/modules/shape/doc/shape_distances.html" rel="nofollow">this link</a> in Opencv API Reference but i cant find How to use it anywhere.
  Could anyone please guide me how to use this functions?</p>
