SourceImageOrientationCorrection | Amazon.Rekognition.OrientationCorrection |
Gets and sets the property SourceImageOrientationCorrection.
The value of If the input image is in .jpeg format, it might contain exchangeable image file format (Exif) metadata that includes the image's orientation. Amazon Rekognition uses this orientation information to perform image correction. The bounding box coordinates are translated to represent object locations after the orientation information in the Exif metadata is used to correct the image orientation. Images in .png format don't contain Exif metadata. Amazon Rekognition doesn’t perform image correction for images in .png format and .jpeg images without orientation information in the image Exif metadata. The bounding box coordinates aren't translated and represent the object locations before the image is rotated. |

Gets and sets the property UnmatchedFaces. An array of faces in the target image that did not match the source image face. |
Examples
This operation compares the largest face detected in the source image with each face detected in the target image.
To compare two images
var client = new AmazonRekognitionClient();
var response = client.CompareFaces(new CompareFacesRequest
{
SimilarityThreshold = 90,
SourceImage = new Image { S3Object = new S3Object {
Bucket = "mybucket",
Name = "mysourceimage"
} },
TargetImage = new Image { S3Object = new S3Object {
Bucket = "mybucket",
Name = "mytargetimage"
} }
});
List<CompareFacesMatch> faceMatches = response.FaceMatches;
ComparedSourceImageFace sourceImageFace = response.SourceImageFace;
