ocrd_calamari

Recognize text using Calamari OCR.

Introduction

This offers a OCR-D compliant workspace processor for some of the functionality of Calamari OCR.

This processor only operates on the text line level and so needs a line segmentation (and by extension a binarized image) as its input.

pip install ocrd_calamari

pip install .

Download standard models:

wget https://github.com/Calamari-OCR/calamari_models/archive/master.zip
unzip master.zip

Download models trained on GT4HistOCR data:

make gt4histocr-calamari
ls gt4histocr-calamari

ocrd-calamari-recognize -p test-parameters.json -m mets.xml -I OCR-D-SEG-LINE -O OCR-D-OCR-CALAMARI

With test-parameters.json:

{
    "checkpoint": "/path/to/some/trained/models/*.ckpt.json"
}

For information regarding development and testing, please see README-DEV.md.
