My OCR-D workflow
|
|
=================
|
|
|
|
[](https://travis-ci.org/mikegerber/my_ocrd_workflow)
|
|
|
|
WIP. Given a OCR-D workspace with document images in the OCR-D-IMG file group,
|
|
this workflow produces:
|
|
|
|
* Binarized images
|
|
* Line segmentation
|
|
* OCR text (using Calamari and Tesseract, both with GT4HistOCR models)
|
|
* (Given ground truth in OCR-D-GT-PAGE, also an OCR text evaluation report)
|
|
|
|
If you're interested in the exact processors, versions and parameters, please take a look at the [script](my_ocrd_workflow) and possibly the [Dockerfile](Dockerfile) and the [requirements](requirements.txt).
|
|
|
|
Goal
|
|
----
|
|
Provide a **test environment** to produce OCR output for historical prints, using OCR-D, especially [ocrd_calamari](https://github.com/OCR-D/ocrd_calamari) and [sbb_textline_detection](https://github.com/qurator-spk/sbb_textline_detection), including all dependencies in Docker.

How to use
|
|
----------
|
|
It's easiest to use it as a container. To build the container using Docker:
|
|
~~~
|
|
cd ~/devel/my_ocrd_workflow
|
|
./build
|
|
~~~
|
|
|
|
To run the container on an example workspace:
|
|
~~~
|
|
# Download an example workspace
|
|
cd /tmp
|
|
wget https://qurator-data.de/examples/actevedef_718448162.first-page.zip
|
|
unzip actevedef_718448162.first-page.zip
|
|
|
|
# Run the workflow on it
|
|
cd actevedef_718448162.first-page
|
|
~/devel/my_ocrd_workflow/run
|
|
~~~
|
|
|
|
### Viewing results
|
|
You may then examine the results using
|
|
[PRImA's PAGE Viewer](https://www.primaresearch.org/tools/PAGEViewer):
|
|
~~~
|
|
java -jar /path/to/JPageViewer.jar --resolve-dir . OCR-D-OCR-CALAMARI/OCR-D-OCR-CALAMARI_00000024.xml
|
|
~~~
|
|
|
|
The workflow also produces OCR evaluation reports using
|
|
[dinglehopper](https://github.com/qurator-spk/dinglehopper), if ground truth was
|
|
available:
|
|
~~~
|
|
firefox OCR-D-OCR-CALAMARI-EVAL/OCR-D-OCR-CALAMARI-EVAL_00000024.html
|
