public sealed class ObjectTrackingAnnotation : IMessage<ObjectTrackingAnnotation>, IEquatable<ObjectTrackingAnnotation>, IDeepCloneable<ObjectTrackingAnnotation>, IBufferMessage, IMessage
public RepeatedField<ObjectTrackingFrame> Frames { get; }
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.
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.
