Labeling Workflow

The labeling workflow includes AWS Step Functions and AWS Lambda, which create and manage labeling jobs. The labeling job creates a dataset, including faces, for indexing. Annotation results are indexed to Amazon Rekognition face collection. Amazon SNS sends a notification to the responsible work team that will work on the labeling job. After the work team completes the job, the labeling state machine collects the annotations and indexes the annotation results to the Amazon Rekognition face collection. The unique face IDs are stored in an Amazon DynamoDB table.
