[0,0,0,0] boxes leaking?

[Nekronik]

Hello, I noticed that in some situations persons are detected where the face has a box of [0,0,0,0]

Correct me if I am wrong but, I think a box of area 0 means that there is no face and should not be included in the results.

I spotted that these 0-area-boxes appear in at least two situations:

1. At the same pace of skipTime (I have it set to 1000ms)
   
2. When nothing is detected, as many as maxDetected 0-area-boxes are returned (I have it set as 3 for the example)
   

I noticed that the results rate when nothing is detected is slower and I guess this is because it tries to spend more time detecting anything when nothing is found.

For the record:

• I spotted this behavior in versions 2.5.1 and 2.5.7 (did not test it in any more than this)
• nothing else (i.e. gestures) apart from a 0-area-box is inside any of these "persons":
  

Is this the expected behavior? I did not know if I had to open this as an issue or discussion.

definitely a bug, i've created issue #241 to track it.
