title: OpenCV for ANDROID image compare
body: <p>I want to develop app which will recognize object(like monument or something) present in front of camera using <code>OpenCv</code> and then it will show information about it. </p>
  
  <p>So the question is <strong>how to recognize object</strong>(like monument or something) shape or compare to images with <code>OpenCV</code>? <br>
  And what is the best method for doing this?</p>
  
  <p>It would be good if there was some kind of samples or tutorials for object detection and comparison.</p>
  
  <p>Thank you.</p>
