| # Text Region Detection in Historical Astronomical Diagrams |
|
|
| Official repository of the paper _"Text region detection in historical astronomical diagrams"_. We introduce the first large, diverse, open-access dataset of **948** historical astronomical diagrams annotated with **10,940** oriented polygonal text regions that spans ten centuries (8<sup>th</sup> to 18<sup>th</sup>) and seven major traditions: Arabic, Persian, Chinese, Byzantine, Latin, Hebrew, and Sanskrit. |

| # Dataset 📜 |
| ## Content |
| We provide our dataset under two directories, namely `EIDA` and `EIDALatin`, with annotations in `LabelMe` format. `EIDA` contains images and associated annotations of all traditions (including Latin) under `train`, `val`, and `test` splits: |
| ``` |
| EIDA/ |
| ├── train/ |
| │ ├── <filename_1>.jpg |
| │ ├── <filename_1>.json |
| │ │ . |
| │ │ . |
| │ ├── <filename_N>.jpg |
| │ └── <filename_N>.json |
| ├── val/ |
| └── test/ |
| ``` |
|
|
| For class-aware annotations, we provide `EIDALatin`, which contains Latin subset with text classes, and splits in `.txt` format: |
| ``` |
| EIDALatin/ |
| ├── data/ |
| │ ├── <filename_1>.jpg |
| │ ├── <filename_1>.json |
| │ │ . |
| │ │ . |
| │ ├── <filename_N>.jpg |
| │ └── <filename_N>.json |
| ├── train.txt |
| ├── val.txt |
| └── test.txt |
| ``` |
