AWSRekognitionAuditImage

Objective-C

@interface AWSRekognitionAuditImage

Swift

class AWSRekognitionAuditImage

An image that is picked from the Face Liveness video and returned for audit trail purposes, returned as Base64-encoded bytes.

  • Identifies the bounding box around the label, face, text, object of interest, or personal protective equipment. The left (x-coordinate) and top (y-coordinate) are coordinates representing the top and left sides of the bounding box. Note that the upper-left corner of the image is the origin (0,0).

    The top and left values returned are ratios of the overall image size. For example, if the input image is 700x200 pixels, and the top-left coordinate of the bounding box is 350x50 pixels, the API returns a left value of 0.5 (350/700) and a top value of 0.25 (50/200).

    The width and height values represent the dimensions of the bounding box as a ratio of the overall image dimension. For example, if the input image is 700x200 pixels, and the bounding box width is 70 pixels, the width returned is 0.1.

    The bounding box coordinates can have negative values. For example, if Amazon Rekognition is able to detect a face that is at the image edge and is only partially visible, the service can return coordinates that are outside the image bounds and, depending on the image edge, you might get negative values or values greater than 1 for the left or top values.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSRekognitionBoundingBox *_Nullable boundingBox;

    Swift

    var boundingBox: AWSRekognitionBoundingBox? { get set }

  • The Base64-encoded bytes representing an image selected from the Face Liveness video and returned for audit purposes.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSData *_Nullable bytes;

    Swift

    var bytes: Data? { get set }

  • Provides the S3 bucket name and object name.

    The region for the S3 bucket containing the S3 object must match the region you use for Amazon Rekognition operations.

    For Amazon Rekognition to process an S3 object, the user must have permission to access the S3 object. For more information, see How Amazon Rekognition works with IAM in the Amazon Rekognition Developer Guide.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSRekognitionS3Object *_Nullable s3Object;

    Swift

    var s3Object: AWSRekognitionS3Object? { get set }
