Menambahkan lebih banyak gambar ke dataset
Anda dapat menambahkan lebih banyak gambar ke kumpulan data Anda dengan menggunakan konsol Amazon Rekognition Custom Labels atau dengan memanggilUpdateDatasetEntries API.
Menambahkan lebih banyak gambar (konsol)
Saat Anda menggunakan konsol Amazon Rekognition Custom Labels, Anda mengunggah gambar dari komputer lokal. Gambar ditambahkan ke lokasi bucket Amazon S3 (konsol atau eksternal) tempat gambar yang digunakan untuk membuat kumpulan data disimpan.
Untuk menambahkan lebih banyak gambar ke set data Anda (konsol)
Buka konsol Amazon Rekognition di https://console.aws.amazon.com/rekognition/.
-
Di panel sebelah kiri, pilih Gunakan Label Kustom. Halaman arahan Amazon Rekognition Custom Labels ditampilkan.
-
Di panel navigasi kiri, pilih Proyek. Tampilan Proyek ditampilkan.
-
Pilih proyek yang ingin Anda gunakan.
-
Di panel navigasi kiri kiri kiri kiri kiri kiri kiri kiri kiri kiri, pilih Set Data.
-
Pilih Actions dan pilih set data yang ingin Anda tambahkan gambar.
-
Pilih gambar yang ingin Anda unggah ke set data. Anda dapat menyeret gambar atau memilih gambar yang ingin Anda unggah dari komputer lokal Anda. Anda dapat mengunggah hingga 30 gambar sekaligus.
-
Pilih Unggah gambar.
-
Pilih Save changes (Simpan perubahan).
-
Beri label pada gambar. Untuk informasi selengkapnya, lihat Pelabelan gambar.
Menambahkan lebih banyak gambar (SDK)
UpdateDatasetEntriesmemperbarui atau menambahkan baris JSON ke file manifes. Anda melewati baris JSON sebagai objek data byte64 dikodekan diGroundTruth lapangan. Jika Anda menggunakanAWS SDK untuk meneleponUpdateDatasetEntries, SDK akan mengkodekan data untuk Anda. Setiap baris JSON berisi informasi untuk satu gambar, seperti label yang ditetapkan atau informasi kotak pembatas. Misalnya:
{"source-ref":"s3://bucket/image","BB":{"annotations":[{"left":1849,"top":1039,"width":422,"height":283,"class_id":0},{"left":1849,"top":1340,"width":443,"height":415,"class_id":1},{"left":2637,"top":1380,"width":676,"height":338,"class_id":2},{"left":2634,"top":1051,"width":673,"height":338,"class_id":3}],"image_size":[{"width":4000,"height":2667,"depth":3}]},"BB-metadata":{"job-name":"labeling-job/BB","class-map":{"0":"comparator","1":"pot_resistor","2":"ir_phototransistor","3":"ir_led"},"human-annotated":"yes","objects":[{"confidence":1},{"confidence":1},{"confidence":1},{"confidence":1}],"creation-date":"2021-06-22T10:11:18.006Z","type":"groundtruth/object-detection"}}
Untuk informasi selengkapnya, lihat Membuat file manifes.
Gunakansource-ref kolom sebagai kunci untuk mengidentifikasi gambar yang ingin Anda perbarui. Jika dataset tidak berisi nilaisource-ref bidang yang cocok, baris JSON ditambahkan sebagai gambar baru.
Untuk menambahkan lebih banyak gambar ke dataset (SDK)
-
Jika Anda belum melakukannya, instal dan konfigurasikanAWS CLI danAWS SDK. Untuk informasi selengkapnya, lihat Langkah 4: Siapkan AWS CLI and AWS SDKs.
-
Gunakan contoh berikut untuk menambahkan baris JSON ke dataset.
- CLI
-
Ganti nilaiGroundTruth dengan Garis JSON yang ingin Anda gunakan. Anda perlu untuk melarikan diri setiap karakter khusus dalam JSON Line.
aws rekognition update-dataset-entries\
--dataset-arn dataset_arn \
