## Dataset Description

- **Homepage:** [Europeana](https://europeana.transcribathon.eu/documents/story/?story=121795/)
- **Point of Contact:** [TEKLIA](https://teklia.com)

## Dataset Summary

The PELLET Casimir Marius dataset includes 100 annotated French letters written between 1914 and 1918.
Annotations were done at line-level and all images do not have any text.

Note that all images are resized to a fixed height of 128 pixels.

### Languages

All the documents in the dataset are written in French.

## Dataset Structure

### Data Instances

```
{
  'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=1684x128 at 0x1A800E8E190,
  'text': 'LE HAVRE - panorama de la rue de Paris'
}
```

### Data Fields

- `image`: a PIL.Image.Image object containing the image. Note that when accessing the image column (using dataset[0]["image"]), the image file is automatically decoded. Decoding of a large number of image files might take a significant amount of time. Thus it is important to first query the sample index before the "image" column, i.e. dataset[0]["image"] should always be preferred over dataset["image"][0].
- `text`: the label transcription of the image.

## Usage with the PyLaia library

1. **Clone the repository** via 
   1. the Settings on the UI,
   2. or `GIT_LFS_SKIP_SMUDGE=1 git clone https://huggingface.co/datasets/Teklia/PELLET-Casimir-Marius-line`
2. The dataset is available in [PyLaia format](https://atr.pages.teklia.com/pylaia/usage/datasets/format/), in the `./data` folder.

You can use this dataset to:
- train a new PyLaia model,
- assess your model's performance against this dataset.
