title: Is it possible to use OpenCV to accurately detect water in a sewage pipe?
body: <p>I'm looking into image-recognition of water in sewage pipes for a future project.</p>
  
  <p>I have been looking into OpenCV, and it looks like it is very good at recognizing where objects start, and stop. However, is there anything in OpenCV that would not only allow for separating water from pipe, but also identifying which is which?</p>
  
  <p>Edit: Here is an example of the image type (taken from video):
