↳ track_id int|string

Streaming mode ONLY. In streaming mode, we do not know the end time of a tracked object before it is completed. Hence, there is no VideoSegment info returned. Instead, we provide a unique identifiable integer track_id so that the customers can correlate the results of the ongoing ObjectTrackAnnotation of the same track_id over time.

↳ entity Google\Cloud\VideoIntelligence\V1\Entity

Entity to specify the object category that this track is labeled as.

↳ confidence float

Object category's labeling confidence of this track.

↳ frames array<Google\Cloud\VideoIntelligence\V1\ObjectTrackingFrame>

Information corresponding to all frames where this object track appears. Non-streaming batch mode: it may be one or multiple ObjectTrackingFrame messages in frames. Streaming mode: it can only be one ObjectTrackingFrame message in frames.
