In the notebook I created, I added support for additional input formats and a feature to save to Google Drive.
How to Use
The usage is almost the same as the NDLOCR application. Please refer to the following video.
Features
As a notable feature, I converted the recognition results into an IIIF manifest format, making them viewable in the Mirador viewer. Specifically, the following output is produced.
By clicking the latter link, the following Mirador viewer is displayed, allowing you to review the recognition results.
This IIIF manifest file is also stored in Google Drive.
