Does it have some timeout for face disappearing?

Hello! Thank you for your great project! I'm planning to try your code for face tracking in the crowd. As I understand from https://github.com/YuvalNirkin/find_face_landmarks/blob/master/sequence_face_landmarks/face_tracker_brisk.cpp you currently don't implement face removing from unmatched faces list after some timeout (so it can increase fps and help to avoid some false positives matches)

Is it true and what caveats do you have about it?

Try to use the LBP tracker: https://github.com/YuvalNirkin/find_face_landmarks/blob/master/sequence_face_landmarks/face_tracker_lbp.cpp

It does implement what you suggest but it's a little slower.
