# Binarization
> Binarization for document images
## Introduction
This tool performs document image binarization (i.e. transform colour/grayscale
to black-and-white pixels) for OCR using multiple trained models.
## Installation
Clone the repository, enter it and run
`pip install .`
### Models
Pre-trained models can be downloaded from here:
https://qurator-data.de/sbb_binarization/
## Usage
```sh
sbb_binarize \
--patches \
-m <directory with models> \
<input image> \
<output image>
```
**Note** In virtually all cases, the `--patches` flag will improve results.
