# Doc-UFCN - NorHand v1 - Line detection
The NorHand v1 line detection model predicts the following elements from NorHand document images:
- vertical text lines;
- horizontal text lines.
This model was developed during the [HUGIN-MUNIN project](https://hugin-munin-project.github.io/).
## Model description
The model has been trained using the Doc-UFCN library on the NorHand dataset.
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:
| set | class | IoU | F1 | AP@[.5] | AP@[.75] | AP@[.5,.95] |
| :---- | :--------- | ----: | ----: | ------: | -------: | ----------: |
| train | vertical | 88.29 | 89.67 | 71.37 | 33.26 | 36.32 |
| | horizontal | 69.81 | 81.35 | 91.73 | 36.62 | 45.67 |
| val | vertical | 73.01 | 75.13 | 46.02 | 4.99 | 15.58 |
| | horizontal | 61.65 | 75.69 | 87.98 | 11.18 | 31.55 |
| test | vertical | 78.62 | 80.03 | 59.93 | 15.90 | 24.11 |
| | horizontal | 63.59 | 76.49 | 95.93 | 24.18 | 41.45 |
