# Historical Printed Ornaments: Dataset and Tasks

Official repository of the paper _"Historical Printed Ornaments: Dataset and Tasks"_. We introduce **_Rey's Ornaments dataset_** which focuses on an XVIIIth century bookseller, Marc Michel Rey, providing a consistent set of ornaments with a wide diversity and representative challenges. We additinally highlight three complex tasks that are of critical interest to book historians: (a) clustering, (b) element discovery, and (c) unsupervised change localization.

## Datasets 📜 and Evaluation 📈

We offer three task-specific subsets of **_Rey's Ornaments dataset_**:

```
./
├── clustering
├── element_discovery
└── change_localization
```
Detailed explanations of datasets, tasks, baselines and evaluation demos are presented in following ReadMe files:
- clustering [ReadMe](https://github.com/printed-ornaments/reys-dataset/tree/main/clustering/README.md)
- element discovery [ReadMe](https://github.com/printed-ornaments/reys-dataset/tree/main/element_discovery/README.md)
- change localization [ReadMe](https://github.com/printed-ornaments/reys-dataset/tree/main/change_localization/README.md)
