In Face Recognition, how do we detect a new person whose images are not in the database? The code I am using currently detects a new person with the closest match from the database.

Can't you do a threshold on the match result?

the distance(confidance) value for unknown persons should be significantly higher than the one for known persons.

so, measure it for a couple unknown persons, and then set it as the threshold value in the FaceReco's constructor. this should result in a -1 prediction label for unknown persons.
