PyLaia - Esposalles

This model performs Handwritten Text Recognition in Catalan (19th century).

Model description

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

Training images were resized with a fixed height of 128 pixels, keeping the original aspect ratio.

split	N lines
train	2,328
val	742
test	757

An external 6-gram character language model can be used to improve recognition. The language model is trained on the text from the Esposalles training set.

Evaluation results

The model achieves the following results:

set	Language model	CER (%)	WER (%)	N lines
test	no	0.76	2.62	757
test	yes	1.04	3.38	757

How to use
