title: TensorFlow sees a black screen as an object for 99%
body: <p>I have the problem that TensorFlow detects a black screen as an object?
  I have trained it so it only can see two classes, but I want to see N/A label if its neither the classes.</p>
  
  <p><a href="https://i.stack.imgur.com/Bg9om.png" rel="nofollow noreferrer">Result</a></p>
  
  <p>Hope you guys have any idea how to fix this.</p>
