Mengenali selebriti dalam sebuah citra

Untuk mengenali selebriti dalam sebuah citra

1. Jika belum:

   1. Buat atau perbarui pengguna dengan AmazonRekognitionFullAccess dan AmazonS3ReadOnlyAccess izin. Untuk informasi selengkapnya, lihat Langkah 1: Siapkan AWS akun dan buat Pengguna.

   2. Instal dan konfigurasikan SDK AWS CLI dan AWS. Untuk informasi selengkapnya, lihat Langkah 2: Siapkan AWS CLI and AWS SDKs.

2. Gunakan contoh berikut ini untuk memanggil operasi RecognizeCelebrities.

   Java

   Contoh ini menampilkan informasi tentang selebriti yang terdeteksi dalam sebuah citra.

   AWS CLI

   Perintah AWS CLI ini menampilkan output JSON untuk operasi CLI recognize-celebrities.

   Ubah bucketname dengan nama bucket Amazon S3 yang berisi citra. Ubah input.jpg ke nama file dari sebuah citra yang berisi satu wajah selebriti atau lebih.

   Ganti nilai profile_name dengan nama profil pengembang Anda.

   aws rekognition recognize-celebrities \
     --image "S3Object={Bucket=bucketname,Name=input.jpg}"

   Jika Anda mengakses CLI pada perangkat Windows, gunakan tanda kutip ganda alih-alih tanda kutip tunggal dan hindari tanda kutip ganda bagian dalam dengan garis miring terbalik (yaitu\) untuk mengatasi kesalahan parser yang mungkin Anda temui. Sebagai contoh, lihat berikut ini:

   
                                       aws rekognition recognize-celebrities --image \
                                       "{\"S3Object\":{\"Bucket\":\"bucket-name\",\"Name\":\"image-name\"}}" --profile profile-name
                                   

   Python

   Contoh ini menampilkan informasi tentang selebriti yang terdeteksi dalam sebuah citra.

   Ubah nilai photo dengan nama jalur dan file dari sebuah file citra yang berisi satu wajah selebriti atau lebih.

   Ganti nilai profile_name di baris yang membuat sesi Rekognition dengan nama profil pengembang Anda.
