The LABEL action is used by the Rekognition connector to execute Amazon Rekognition services to identify and label the objects in JPEG and PNG files that are less than 15mb in size.
The Amazon Rekognition API that is called is the Detect Labels API.
Files between 5mb and 15mb are uploaded to an Amazon S3 bucket before processing. The IAM user configured to run the Rekognition service requires:
- Access to this bucket
- Access to the Rekognition service itself
- Permission to rekognition:DetectLabels
The authentication for the Rekognition connector is set using the configuration parameters. For more details, see Rekognition Configuration Parameters.
