이미지에서 안전하지 않은 콘텐츠를 감지하는 방법

다음 detect-moderation-labels 명령은 Amazon S3 버킷에 저장된 지정된 이미지에서 안전하지 않은 콘텐츠를 감지합니다.

aws rekognition detect-moderation-labels \
    --image "S3Object={Bucket=MyImageS3Bucket,Name=gun.jpg}"

출력:

{
    "ModerationModelVersion": "3.0",
    "ModerationLabels": [
        {
            "Confidence": 97.29618072509766,
            "ParentName": "Violence",
            "Name": "Weapon Violence"
        },
        {
            "Confidence": 97.29618072509766,
            "ParentName": "",
            "Name": "Violence"
