AWS::Rekognition::StreamProcessor - AWS CloudFormation

AWS::Rekognition::StreamProcessor

The AWS::Rekognition::StreamProcessor type creates a stream processor used to detect and recognize faces or to detect connected home labels in a streaming video. Amazon Rekognition Video is a consumer of live video from Amazon Kinesis Video Streams. There are two different settings for stream processors in Amazon Rekognition, one for detecting faces and one for connected home features.

If you are creating a stream processor for detecting faces, you provide a Kinesis video stream (input) and a Kinesis data stream (output). You also specify the face recognition criteria in FaceSearchSettings. For example, the collection containing faces that you want to recognize.

If you are creating a stream processor for detection of connected home labels, you provide a Kinesis video stream for input, and for output an Amazon S3 bucket and an Amazon SNS topic. You can also provide a KMS key ID to encrypt the data sent to your Amazon S3 bucket. You specify what you want to detect in ConnectedHomeSettings, such as people, packages, and pets.

You can also specify where in the frame you want Amazon Rekognition to monitor with BoundingBoxRegionsOfInterest and PolygonRegionsOfInterest. The Name is used to manage the stream processor and it is the identifier for the stream processor. The AWS::Rekognition::StreamProcessor resource creates a stream processor in the same Region where you create the Amazon CloudFormation stack.

For more information, see CreateStreamProcessor.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

Properties

BoundingBoxRegionsOfInterest

List of BoundingBox objects, each of which denotes a region of interest on screen. For more information, see the BoundingBox field of RegionOfInterest.

Required: No

Type: List of BoundingBox

Update requires: Replacement

ConnectedHomeSettings

Connected home settings to use on a streaming video. You can use a stream processor for connected home features and select what you want the stream processor to detect, such as people or pets. When the stream processor has started, one notification is sent for each object class specified. For more information, see the ConnectedHome section of StreamProcessorSettings.

Required: No

Type: ConnectedHomeSettings

Update requires: Replacement

DataSharingPreference

Allows you to opt in or opt out to share data with Rekognition to improve model performance. You can choose this option at the account level or on a per-stream basis. Note that if you opt out at the account level this setting is ignored on individual streams. For more information, see StreamProcessorDataSharingPreference.

Required: No

Type: DataSharingPreference

Update requires: Replacement

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the name of the stream processor. For example:

{ "Ref": "MyStreamProcessor" }

For more information about using the Ref function, see Ref.

Fn::GetAtt

Fn::GetAtt returns a value for a specified attribute of this type. The following are the available attributes and sample return values. For more information about using Fn::GetAtt, see Fn::GetAtt.
