float com.vdt.face_recognition.sdk.VideoWorker.DatabaseElement.distance_threshold

Distance threshold for a MatchFound event.

Setting a different recognition threshold for different persons may be useful in some cases. For example, if there is a particular criminal in the blacklist, who is more dangerous than the other criminals, and you want to increase the recognition probability for this very person, despite the higher probability of false acceptance error.
