**To compare faces in two images**
The following ``compare-faces`` command compares faces in two images stored in an Amazon S3 bucket. ::
aws rekognition compare-faces \
--source-image '{"S3Object":{"Bucket":"MyImageS3Bucket","Name":"source.jpg"}}' \
--target-image '{"S3Object":{"Bucket":"MyImageS3Bucket","Name":"target.jpg"}}'
