## Usage with OCR-D
|
|
~~~
|
|
ocrd-example-binarize -I OCR-D-IMG -O OCR-D-IMG-BIN
|
|
ocrd_sbb_textline_detector -I OCR-D-IMG-BIN -O OCR-D-SEG-LINE-SBB \
|
|
-p '{ "model": "/path/to/the/models/textline_detection" }'

|
|
Segmentation works on raw RGB images, but respects and retains
|
|
`AlternativeImage`s from binarization steps, so it's a good idea to do
|
|
binarization first, then perform the textline detection. The used binarization
|
|
processor must produce an `AlternativeImage` for the binarized image, not
|
|
replace the original raw RGB image.
