:warning: Development is currently focused on achieving the best possible quality of results for a wide variety of historical documents and therefore processing can be very slow. We aim to improve this, but contributions are welcome.

## Installation
|
||||
Python versions `3.8-3.11` with Tensorflow versions >=`2.12` on Linux are currently supported. Unfortunately we can not currently support Windows or MacOS.
|
||||
Windows users may be able to successfully run the tool through [WSL](https://learn.microsoft.com/en-us/windows/wsl/).
|
||||
Python `3.8-3.11` with Tensorflow `2.12-2.15` on Linux are currently supported.
|
||||
|
||||
For (limited) GPU support the CUDA toolkit needs to be installed.

## Models
|

Pre-trained models can be downloaded from [qurator-data.de](https://qurator-data.de/eynollah/).
|
||||
Pre-trained models can be downloaded from [qurator-data.de](https://qurator-data.de/eynollah/) or [huggingface](https://huggingface.co/SBB?search_models=eynollah).

In case you want to train your own model to use with Eynollah, have a look at [sbb_pixelwise_segmentation](https://github.com/qurator-spk/sbb_pixelwise_segmentation).

In case you want to train your own model, have a look at [`sbb_pixelwise_segmentation`](https://github.com/qurator-spk/sbb_pixelwise_segmentation).
|

|
||||
## Usage
|
||||
The command-line interface can be called like this:
|
||||
|
||||
```sh
|
||||
eynollah \
|
||||
-i <image file> \
|
||||
-i <single image file> | -di <directory containing image files> \

-m <directory containing model files> \
|

[OPTIONS]
|

```
|

The following options can be used to further configure the processing:

| `-ib` | apply binarization (the resulting image is saved to the output directory) |
|

| `-ep` | enable plotting (MUST always be used with `-sl`, `-sd`, `-sa`, `-si` or `-ae`) |
|
||||
| `-ho` | ignore headers for reading order dectection |
|
||||
| `-di <directory>` | process all images in a directory in batch mode |

| `-si <directory>` | save image regions detected to this directory |

| `-sp <directory>` | save cropped page image to this directory |
|
||||
| `-sa <directory>` | save all (plot, enhanced/binary image, layout) to this directory |
|
||||
|

If no option is set, the tool will perform layout detection of main regions (background, text, images, separators and marginals).

The tool produces better quality output when RGB images are used as input than greyscale or binarized images.
