title: Tips for background subtraction in the face of noise
body: <p>Background subtraction is an important primitive in computer vision.  I'm looking at different methods that have been developed, and I've begun thinking about how to perform background subtraction in the face of random, salt and pepper noise.</p>
  
  <p>In a system such as the Microsoft Kinect, the infrared camera will give off random noise pretty consistently.  If you are trying to background subtract from the depth view, how can you avoid an issue with this random noise while reliably subtracting the background?</p>
