title: PCL - Papers/algorithms implemented
body: <p>Is there any systematic way to find out which paper is implemented for PCL library functions?
  e.g. which paper was implemented for the registration functions?</p>
  
  <p>I had the same question about OpenCV, but apparently for OpenCV one relies just on the documentation, where sometimes the corresponding paper is mentioned e.g. <a href="http://docs.opencv.org/modules/imgproc/doc/miscellaneous_transformations.html?highlight=distance%20transform#void%20distanceTransform%28InputArray%20src,%20OutputArray%20dst,%20OutputArray%20labels,%20int%20distanceType,%20int%20maskSize,%20int%20labelType%29" rel="nofollow">here</a></p>
  
  <p>Thanks!</p>
