CompositeDetectedPerson.msg

# Specifies which detected persons have been merged into a composite detection by the spencer_detected_person_association module.

# TODO: Do we need a composite person-specific timestamp (or even a full message header including frame ID)?
# Having a separate timestamp per person could be useful if the timestamps of the merged DetectedPersons messages vary a lot,
# and some persons are only seen by a single sensor (so averaging over all input timestamps would have a detrimental effect).
