public sealed class Annotation : IMessage<Annotation>, IEquatable<Annotation>, IDeepCloneable<Annotation>, IBufferMessage, IMessage
Reference documentation and code samples for the Data Labeling v1beta1 API class Annotation.
Annotation for Example. Each example may have one or more annotations. For
example in image classification problem, each image might have one or more
labels. We call labels binded with this image an Annotation.
