コレクションに顔を追加するには
次の
index-faces
コマンドは、画像内の顔を指定されたコレクションに追加します。aws rekognition index-faces \ --image '
{"S3Object":{"Bucket":"MyVideoS3Bucket","Name":"MyPicture.jpg"}}
' \ --collection-idMyCollection
\ --max-faces1
\ --quality-filter"AUTO"
\ --detection-attributes"ALL"
\ --external-image-id"MyPicture.jpg"
