# Belfort handwritten text recognition
|
| 18 |
+
|
| 19 |
+
This model performs Handwritten Text Recognition in French on historical documents.
|
| 20 |
+
|
| 21 |
+
## Model description
|
| 22 |
+
|
| 23 |
+
The model was trained using the PyLaia library on the [Belfort dataset](https://zenodo.org/records/8041668).
|
| 24 |
+
|
| 25 |
+
For training, text-lines were resized with a fixed height of 128 pixels, keeping the original aspect ratio. Vertical lines are discarded.
|
| 26 |
+
|
| 27 |
+
| split | N lines |

| test | 3,819 |
|
| 32 |

|
| 33 |
+
An external 6-gram character language model can be used to improve recognition. The language model is trained on the text from the NorHand v2 training set.
|
| 34 |
+
|
| 35 |
+
## Evaluation results
