# Doc-UFCN - Generic historical line detection

The generic historical line detection model predicts text lines from document images.

## Model description

The model has been trained using the Doc-UFCN library on 10 historical document datasets including these public datasets:
  * [Bozen](https://zenodo.org/record/218236)
  * [cBAD2017 (READ)](https://zenodo.org/record/1491441)
  * [cBAD2019](https://zenodo.org/record/2567398)
  * [DIVA-HisDB](https://diuf.unifr.ch/main/hisdoc/diva-hisdb.html)
  * [Horae](https://github.com/oriflamms/HORAE/)
  * [ScribbleLens](https://www.openslr.org/84/)

It has been trained on images with their largest dimension equal to 768 pixels, keeping the original aspect ratio.

## Evaluation results

The model achieves the following results on the test sets:

|                         | IoU   | F1    | AP@[.5] | AP@[.75] | AP@[.5,.95] |
| ----------------------- | ----: | ----: | ------: | -------: | ----------: |
| Bozen                   | 60.15 | 75.10 | 97.14   | 3.79     | 27.50       |
| cBAD2017 (READ) Complex | 46.79 | 60.35 | 56.01   | 3.40     | 16.26       |
| cBAD2017 (READ) Simple  | 53.97 | 68.43 | 57.26   | 8.45     | 19.39       |
| cBAD2019                | 50.77 | 64.52 | 35.46   | 2.88     | 11.51       |
| DIVA-HisDB              | 41.54 | 57.88 | 63.15   | 0.00     | 11.69       |
| Horae                   | 48.93 | 63.95 | 57.45   | 5.20     | 15.55       |
| ScribbleLens            | 76.61 | 86.72 | 98.02   | 71.87    | 58.32       |

The model has been trained to reduce mergers in predictions (see the [paper](https://link.springer.com/article/10.1007/s10032-022-00395-7) for more details on training). Therefore, despite slightly low evaluation values, the model correctly detects lines on a wide variety of historical and modern manuscript documents.
