* Support for up to 10 segmentation classes:
|
|
|
|
|
* background, page border, text region, text line, header, image, separator, marginalia, initial (drop capital), table
|
|
|
|
|
* Support for various image optimization operations:
|
|
|
|
|
* cropping (border detection), binarization, deskewing, dewarping, scaling, enhancing, resizing
|
|
|
|
|
* Text line segmentation to bounding boxes or polygons (contours) including curved lines and vertical text
|
|
|
|
|
* Detection of reading order
|
|
|
|
|
* Output in [PAGE-XML](https://github.com/PRImA-Research-Lab/PAGE-XML) format

## Installation
|
|
|
|
|
`pip install .` or
|
|
|
|
|
Python versions `3.7-3.10` with Tensorflow `>=2.4` are currently supported.
|
|
|
|
|
|
|
|
|
|
`pip install -e .` for editable installation
|
|
|
|
|
For (minimal) GPU support the [matching](https://www.tensorflow.org/install/source#gpu) CUDA toolkit `>=10.1` needs to be installed.

The current version of Eynollah runs on Python `>=3.7` with Tensorflow `>=2.4`.
|
|
|
|
|
```
|
|
|
|
|
git clone git@github.com:qurator-spk/eynollah.git
|

|
cd eynollah; pip install -e .
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
In order to use a GPU for inference, the CUDA toolkit version 10.x needs to be installed.
|
|
|
|
|
Alternatively, you can run `make install` or `make install-dev` for editable installation.

|
|
|
|
|
|
|
|
|
Alternatively, running `make models` will download and extract models to `$(PWD)/models_eynollah`.
