False positive in object detection

Hi !

I've follow the tutorial "object detection in a scene" and that's work pretty well. But I still have a question.

In my little app, i want to know which object (in a list) is in the scene. When the object is really in the scene, there is no problem (that's a really good point). But the algorithm is always finding a match, even if the object is not in the scene. Most of the time, when the result is wrong, the 4 points don't form a square, it's a line, a big point or something like an hourglass.

Is there a function who can detect / evaluate the probability of a false positive, or i have to do some math by myself ? :)
