Himanis handwritten text recognition

This model performs Handwritten Text Recognition in French on medieval documents.

Model description

The model was trained using the PyLaia library on two medieval datasets:

Himanis (French)
HOME Alcar (Latin)

For training, text-lines 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 Himanis training set.

Evaluation results

The model achieves the following results:

set	Language model	CER (%)	WER (%)	N lines
test	no	9.87	29.25	2241
test	yes	8.87	24.37	2241

How to use
