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 a false acceptance error.
