Configuring Confidence Threshold¶
FindFace Security verifies that a detected face and some face from the dossiers belong to the same person (i. e. the faces match), based on the pre-defined similarity threshold. The default threshold is set to 0.75 which can be considered as optimum. If necessary, you can change the threshold on the Settings tab.
The higher is the threshold, the less are chances that a wrong person will be positively verified, however, some valid photos may also fail verification.
You can configure your system to save and display an event only if the faces match (the
IGNORE_UNMATCHED option at
/etc/ffsecurity/config.py, see Basic Configuration).
