pylaia-norhand-v1

PyLaia - NorHand v1

This model performs Handwritten Text Recognition in Norwegian. It was developed during the HUGIN-MUNIN project.

Model description

The model has been trained using the PyLaia library on the NorHand v1 dataset.

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 v1 training set.

Evaluation results

The model achieves the following results:
