Mencari pengguna (ID wajah/ID pengguna)

Untuk mencari pengguna (SDK)

1. Jika belum:

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

   2. Instal dan konfigurasikan AWS CLI dan AWS SDKs. Untuk informasi selengkapnya, lihat Langkah 2: Mengatur AWS CLI dan AWS SDKs.

2. Gunakan contoh berikut untuk memanggil operasi SearchUsers.

   Java

   Contoh Java ini mencari pengguna dalam koleksi menggunakan operasi. SearchUsers

   import com.amazonaws.services.rekognition.AmazonRekognition;
   import com.amazonaws.services.rekognition.AmazonRekognitionClientBuilder;
   import com.amazonaws.services.rekognition.model.UserMatch;
   import com.amazonaws.services.rekognition.model.SearchUsersRequest;
   import com.amazonaws.services.rekognition.model.SearchUsersResult;
   import com.amazonaws.services.rekognition.model.UserMatch;
   
   public class SearchUsers {
       //Replace collectionId and faceId with the values you want to use.
   
       public static final String collectionId = "MyCollection";
       public static final String faceId = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx";
   
       public static final String userd = 'demo-user';
   
       public static void main(String[] args) throws Exception {
   
           AmazonRekognition rekognitionClient = AmazonRekognitionClientBuilder.defaultClient();
   
           // Search collection for faces matching the user id.
           SearchUsersRequest request = new SearchUsersRequest()
                   .withCollectionId(collectionId)
                   .withUserId(userId);
   
           SearchUsersResult result =
                   rekognitionClient.searchUsers(request);
   
           System.out.println("Printing first search result with matched user and similarity score");
           for (UserMatch match: result.getUserMatches()) {
               System.out.println(match.getUser().getUserId() + " with similarity score " + match.getSimilarity());
           }
   
           // Search collection for faces matching the face id.
           SearchUsersRequest request1 = new SearchUsersRequest()
                   .withCollectionId(collectionId)
                   .withFaceId(faceId);
   
           SearchUsersResult result1 =
                   rekognitionClient.searchUsers(request1);
   
           System.out.println("Printing second search result with matched user and similarity score");
           for (UserMatch match: result1.getUserMatches()) {
               System.out.println(match.getUser().getUserId() + " with similarity score " + match.getSimilarity());
           }
       }
   

   AWS CLI
