# Riconoscimento di celebrità in un video archiviato
<a name="celebrities-video-sqs"></a>

Il riconoscimento di volti celebri di Video Amazon Rekognition nei video archiviati è un'operazione asincrona. Per riconoscere le celebrità in un video archiviato, utilizzalo per avviare l'analisi video. [StartCelebrityRecognition](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_StartCelebrityRecognition.html) Amazon Rekognition per video pubblica lo stato di completamento dell'analisi video in un argomento Amazon Simple Notification Service. Se l'analisi video ha esito positivo, effettua la chiamata a [GetCelebrityRecognition](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_GetCelebrityRecognition.html) per ottenere i risultati dell'analisi. Per ulteriori informazioni su come avviare analisi video e ottenere i risultati, consultare [Chiamata delle operazioni Video Amazon Rekognition](api-video.md). 

La procedura si espande nel codice in [Analisi di un video archiviato in un bucket Amazon S3 con Java o Python (SDK)](video-analyzing-with-sqs.md), che utilizza una coda di Amazon SQS per ottenere lo stato di completamento di una richiesta di analisi video. Per eseguire questa procedura, è necessario disporre di un file video contenente uno o più volti celebri.

**Per individuare le celebrità in un video archiviato in un bucket Amazon S3 (SDK)**

1. Eseguire [Analisi di un video archiviato in un bucket Amazon S3 con Java o Python (SDK)](video-analyzing-with-sqs.md).

1. Aggiungere il seguente codice alla classe `VideoDetect` creata nella fase 1.

#### [ Node.JS ]

   Nel seguente esempio di Node.Js codice, sostituisci il valore di `amzn-s3-demo-bucket` con il nome del bucket S3 contenente il tuo video e il valore di `videoName` con il nome del file video. Dovrai inoltre sostituire il valore di `roleArn` con l'ARN associato al tuo ruolo di servizio IAM. Infine, sostituisci il valore di `region` con il nome della regione operativa associata al tuo account. Sostituisci il valore di `profile_name` nella riga che crea la sessione di Rekognition con il nome del tuo profilo di sviluppatore.

#### [ CLI ]

   Esegui il AWS CLI comando seguente per iniziare a rilevare le celebrità in un video.

   ```
   aws rekognition start-celebrity-recognition --video "{"S3Object":{"Bucket":"amzn-s3-demo-bucket","Name":"video-name"}}" \
   --notification-channel "{"SNSTopicArn":"topic-arn","RoleArn":"role-arn"}" \
   --region region-name --profile profile-name
   ```

   Aggiorna i seguenti valori:
   + Modifica `amzn-s3-demo-bucket` e `video-name` con il nome del bucket Amazon S3 e il nome del file specificati nella fase 2.
   + Cambia `region-name` con la regione AWS che stai utilizzando.
   + Sostituisci il valore di `profile-name` con il nome del tuo profilo di sviluppatore.
   + Cambia `topic-ARN` con l'ARN dell'argomento Amazon SNS creato nella fase 3 di [Configurazione di Video Amazon Rekognition](api-video-roles.md).
   + Modifica `role-ARN` con l'ARN del ruolo di servizio IAM creato nella fase 7 di [Configurazione di Video Amazon Rekognition](api-video-roles.md).

   Se accedi alla CLI da un dispositivo Windows, usa le virgolette doppie anziché le virgolette singole ed evita le virgolette doppie interne tramite barra rovesciata (ovvero, \\) per risolvere eventuali errori del parser che potresti riscontrare. Un esempio è fornito di seguito: 

   ```
   aws rekognition start-celebrity-recognition --video "{\"S3Object\":{\"Bucket\":\"amzn-s3-demo-bucket\",\"Name\":\"video-name\"}}" \
   --notification-channel "{\"SNSTopicArn\":\"topic-arn\",\"RoleArn\":\"role-arn\"}" \
   --region region-name --profile profile-name
   ```

   Dopo aver eseguito l'esempio di codice precedente, copia il `jobID` restituito e inseriscilo nel comando `GetCelebrityRecognition` di seguito per ottenere i risultati, sostituendo `job-id-number` con il `jobID` ricevuto in precedenza: 

   ```
   aws rekognition get-celebrity-recognition --job-id job-id-number --profile profile-name                               
   ```

**Nota**  
Se hai già eseguito un video di esempio diverso da [Analisi di un video archiviato in un bucket Amazon S3 con Java o Python (SDK)](video-analyzing-with-sqs.md), il codice da sostituire potrebbe essere diverso.

1. Eseguire il codice. Vengono visualizzate le informazioni sui volti celebri riconosciuti nel video.

## GetCelebrityRecognition risposta all'operazione
<a name="getcelebrityrecognition-operation-output"></a>

Di seguito è riportata una risposta JSON di esempio. La risposta include quanto segue:
+ **Celebrità riconosciute**: `Celebrities` è una matrice di celebrità e degli orari in cui vengono riconosciute in un video. Esiste un oggetto [CelebrityRecognition](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_CelebrityRecognition.html) per ogni ora in cui viene riconosciuto un volto celebre nel video. Ogni `CelebrityRecognition` contiene informazioni su un volto celebre riconosciuto ([CelebrityDetail](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_CelebrityDetail.html)) e l'ora (`Timestamp`) in cui la celebrità è stata riconosciuta nel video. `Timestamp` si misura in millisecondi dall'inizio del video. 
+ **CelebrityDetail**— Contiene informazioni su una celebrità riconosciuta. Include il nome della celebrità (`Name`), l'identificatore (`ID`), il genere noto della celebrità (`KnownGender`) e un elenco di URL che indirizzano a contenuti correlati (`Urls`). Include anche il livello di fiducia di Amazon Rekognition Video nell'accuratezza del riconoscimento e i dettagli sul volto della celebrità. [FaceDetail](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_FaceDetail.html) [Se hai bisogno di scaricare i contenuti correlati in un secondo momento, puoi utilizzarli con get. `ID` CelebrityInfo](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_GetCelebrityInfo.html) 
+ **VideoMetadata**— Informazioni sul video che è stato analizzato.
