title: Image Stitching parameters seem that there is no one can explain it, please help us to understand it
body: <p>I searched over all the <strong>websites</strong> and <strong>OpenCV documentation</strong> to understand the image stitching parameters, but it seems that there is no one can explain it!!!. There are also many users asked about this parameters, but there is no answer!!!</p>
  
  <p>The parameters are :</p>
  
  <pre><code>setRegistrationResol( ); 
  setSeamEstimationResol( ); 
  setCompositingResol( ); 
  setPanoConfidenceThresh( );
  </code></pre>
  
  <p>We need to understand it in order to optimize the stitching code in term of processing time and quality.</p>
  
  <p><strong>Can any one help us to understand it?? and why the OpenCV documentation didn't explain this parameters?!!</strong></p>
  
  <p>Thank you.</p>
