Belfort handwritten text recognition
This model performs Handwritten Text Recognition in French on historical documents.
Model description
The model was trained using the PyLaia library on the Belfort dataset.
For training, text-lines were resized with a fixed height of 128 pixels, keeping the original aspect ratio. Vertical lines are discarded.

| train | 25,800 |
| val | 3,102 |
| test | 3,819 |
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.
Evaluation results
The model achieves the following results:
| set | Language model | CER (%) | WER (%) | N lines |
|---|---|---|---|---|
| test | no | 10.54 | 28.12 | 3,819 |
| test | yes | 9.52 | 23.73 | 3,819 |
