public class IndexFacesResponse : AmazonWebServiceResponse

The IndexFacesResponse type exposes the following members


Public Method IndexFacesResponse()


Public Property ContentLength System.Int64 Inherited from Amazon.Runtime.AmazonWebServiceResponse.
Public Property FaceModelVersion System.String

Gets and sets the property FaceModelVersion.

Version number of the face detection model associated with the input collection (CollectionId).

Public Property FaceRecords System.Collections.Generic.List<Amazon.Rekognition.Model.FaceRecord>

Gets and sets the property FaceRecords.

An array of faces detected and added to the collection. For more information, see Searching Faces in a Collection in the Amazon Rekognition Developer Guide.

Public Property HttpStatusCode System.Net.HttpStatusCode Inherited from Amazon.Runtime.AmazonWebServiceResponse.
Public Property OrientationCorrection Amazon.Rekognition.OrientationCorrection

Gets and sets the property OrientationCorrection.

The orientation of the input image (counterclockwise direction). If your application displays the image, you can use this value to correct image orientation. The bounding box coordinates returned in FaceRecords represent face locations before the image orientation is corrected.

If the input image is in jpeg format, it might contain exchangeable image (Exif) metadata. If so, and the Exif metadata populates the orientation field, the value of OrientationCorrection is null and the bounding box coordinates in FaceRecords represent face locations after Exif metadata is used to correct the image orientation. Images in .png format don't contain Exif metadata.

Public Property ResponseMetadata Amazon.Runtime.ResponseMetadata Inherited from Amazon.Runtime.AmazonWebServiceResponse.


This operation detects faces in an image and adds them to the specified Rekognition collection.

To add a face to a collection

var response = client.IndexFaces(new IndexFacesRequest 
    CollectionId = "myphotos",
    DetectionAttributes = new List {
    ExternalImageId = "myphotoid",
    Image = new Image { S3Object = new S3Object {
        Bucket = "mybucket",
        Name = "myphoto"
    } }

List faceRecords = response.FaceRecords;
string orientationCorrection = response.OrientationCorrection;
