PyLaia - HOME-Alcar

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

Model description

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

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 HOME-Alcar training set.

Evaluation results

On HOME-Alcar text lines, the model achieves the following results:

set Language model CER (%) WER (%) lines
test no 8.35 26.15 6,932
test yes 7.85 23.20 6,932
