This model performs Handwritten Text Recognition in Norwegian. It was developed during the HUGIN-MUNIN project.
The model has been trained using the PyLaia library on the NorHand v3 document images.
Training images were resized with a fixed height of 128 pixels, keeping the original aspect ratio.

An external 6-gram character language model can be used to improve recognition. The language model is trained on the text from the NorHand v3 training set.
The model achieves the following results:
set | Language model | CER (%) | WER (%) | N lines |
---|---|---|---|---|
test | no | 7.52 | 22.99 | 1,573 |
test | yes | 6.36 | 18.11 | 1,573 |
