PyLaia - NorHand v2
This model performs Handwritten Text Recognition in Norwegian. It was developed during the HUGIN-MUNIN project.
Model description
The model was trained using the PyLaia library on the NorHand v2 dataset.
Training images were resized with a fixed height of 128 pixels, keeping the original aspect ratio.
| set | lines | horizontal lines |
|---|---|---|
| train | 146,693 | 145,061 |
| val | 15,119 | 14,980 |
| test | 1,830 | 1,793 |
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 (%) | lines |
|---|---|---|---|---|
| test | no | 3.82 | 12.00 | 1,573 |
| test | yes | 3.13 | 9.29 | 1,573 |
