TrackingLost callback data.
Constructors
Properties
- best_quality ↔ double
-
Best sample quality over all frames.
read / write
- best_quality_frame_id ↔ int
-
Integer id of the frame of the best quality.
read / write
- best_quality_sample ↔ RawSample?
-
The best quality sample from the best_quality_frame_id frame.
Will be null if "weak_tracks_in_tracking_callback" is enabled and all samples with that track_id are flagged as "weak=true".read / write - best_quality_templ ↔ Template?
-
Template created from best_quality_sample.
Will be null if processing_threads_count is zero or best_quality_sample is NULL.read / write - first_frame_id ↔ int
-
Integer id of the frame on which the face was first detected.
read / write
- hashCode → int
-
The hash code for this object.
read-only, inherited
- last_frame_id ↔ int
-
Integer id of the frame after which the face tracking was lost.
read / write
- runtimeType → Type
-
A representation of the runtime type of the object.
read-only, inherited
- sti_person_id ↔ int
-
ID of "sti_person", which is a set of tracks formed by short time identification.
sti_person_id is equal to track_id of the first mebmer of this "sti_person" set of tracks.read / write - sti_person_id_set ↔ bool
-
Flag indicating that sti_person_id is set. sti_person_id is not set, if short time identification is disabled
or if no templates were generated for this track.
read / write
- stream_id ↔ int
-
Integer id of the video stream (0 <= stream_id < streams_count).
read / write
- track_id ↔ int
-
ID of the lost face (track_id).
track_id is equal to sample.getID() for a sample given in any VideoWorker callback.read / write
