Tracking a face identity#
In LUNA ID, you can track a face identity of the face detected in a video stream during the entire session. This helps you avoid security issues and make sure that the detected face belongs to one person.

To implement face identity tracking, use the LunaConfig.usePrimaryFaceTracking and LunaConfig.faceSimilarityThreshold parameters.
