face_follow_state_t Struct Reference

face follow state keeps the values that move through the subsystem: crop, target, face, last_tick. Some members are pointers into caller- or subsystem-owned memory, so lifetime follows the API that populated them rather than the struct copy itself. More...

Detailed Description

face follow state keeps the values that move through the subsystem: crop, target, face, last_tick. Some members are pointers into caller- or subsystem-owned memory, so lifetime follows the API that populated them rather than the struct copy itself.

One instance per capture source; times are monotonic seconds.
