画像ファイルに対してGoogle Cloud Visionを適用して、IIIFマニフェストおよびTEI/XMLファイルを作成する
概要 画像ファイルに対してGoogle Cloud Visionを適用して、IIIFマニフェストおよびTEI/XMLファイルを作成するライブラリを作成しました。
https://github.com/nakamura196/iiif_tei_py
本ライブラリの使用方法を説明します。
使用方法 以下で使い方などを確認できます。
https://nakamura196.github.io/iiif_tei_py/
ライブラリのインストール GitHubのリポジトリから、ライブラリをインストールします。
pip install https://github.com/nakamura196/iiif_tei_py GCのサービスアカウントの作成 以下の記事などを参考に、GC（Google Cloud）のサービスアカウントキー（JSONファイル）をダウンロードします。

そして、以下のような.envファイルを作成します。
GOOGLE_APPLICATION_CREDENTIALS=your-google-credentials.json 実行 入力サンプル画像として、IIIF Cookbookでも使用されている以下の画像を使用します。
https://iiif.io/api/presentation/2.1/example/fixtures/resources/page1-full.png
以下のようなファイルを作成して実行します。
from iiif_tei_py.core import CoreClient cred_path = CoreClient.load_env() url = "https://iiif.io/api/presentation/2.1/example/fixtures/resources/page1-full.png" output_tei_xml_file_path = "./tmp/01/output.xml" CoreClient.create_tei_xml_with_gocr(url, output_tei_xml_file_path, cred_path, title="Sample") 上記の例では、IIIFマニフェストファイルが./tmp/01/output.jsonに、TEI/XMLファイルが./tmp/01/output.xmlに作成されます。
結果の確認 IIIF IIIFマニフェストファイルをMiradorで表示した例が以下です。
JSONファイルの内容は以下です。
