## Example Usage
Before using `ocrd-calamari-recognize` get some example data and model, and
prepare the document for OCR:
```
# Download model and example data
make gt4histocr-calamari
make actevedef_718448162
~~~
ocrd-calamari-recognize -p test-parameters.json -m mets.xml -I OCR-D-SEG-LINE -O OCR-D-OCR-CALAMARI
~~~
# Create binarized images and line segmentation using other OCR-D projects
ocrd-olena-binarize -p '{ "impl": "sauvola-ms-split" }' -I OCR-D-IMG -O OCR-D-IMG-BINPAGE,OCR-D-IMG-BIN
ocrd-tesserocr-segment-region -I OCR-D-IMG-BINPAGE -O OCR-D-SEG-REGION
ocrd-tesserocr-segment-line -I OCR-D-SEG-REGION -O OCR-D-SEG-LINE
```
With `test-parameters.json`:
~~~
{
"checkpoint": "/path/to/for/example/gt4histocr-calamari/*.ckpt.json",
"textequiv_level": "line"
}
~~~
Finally recognize the text using ocrd_calamari and the downloaded model:
```
ocrd-calamari-recognize -p '{ "checkpoint": "../gt4histocr-calamari/*.ckpt.json" }' -I OCR-D-SEG-LINE -O OCR-D-OCR-CALAMARI
```
You may want to have a look at the [ocrd-tool.json](ocrd_calamari/ocrd-tool.json) descriptions
for additional parameters and default values.
