Come creare una raccolta

Il comando create-collection seguente crea una raccolta con il nome specificato.

aws rekognition create-collection \
    --collection-id "MyCollection"

Output:

{
    "CollectionArn": "aws:rekognition:us-west-2:123456789012:collection/MyCollection",
    "FaceModelVersion": "4.0",
    "StatusCode": 200
}
