PyLaia - CASIA-HWDB2

This model performs Handwritten Text Recognition in Chinese.

Model description

The model was trained using the PyLaia library on the CASIA-HWDB2 dataset.

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

set	lines
train	33,425
val	8,325
test	10,449

An external 6-gram character language model can be used to improve recognition. The language model is trained on the text from the CASIA-HWDB2 training set.

Evaluation results

The model achieves the following results:

set	Language model	CER (%)	lines
test	no	4.61	10,449
test	yes	1.53	10,449
