title: Connected components in organized 3d point cloud data
body: <p>Hy!</p>
  
  <p>I have organized point clouds from a Kinect sensor. Let's say I have a organized point cloud of a sofa with a table in front. What I would like the get are two clouds: sofa and table</p>
  
  <p>I am searching for some algorithm to get the connected components.
  Does anyone have some pseudo code or papers? Or maybe some code (Matlab)</p>
  
  <p>My idea at the moment: I could use the 2D information to get neighboring pixels of a point.
  Next I could check the euclidean distance to the neighboring pixels. If the distance is below a threshold, the pixel belongs to the same cluster. ...</p>
  
  <p>Thanks</p>
