# PyLaia - CASIA-HWDB2 |
|
|
|
This model performs Handwritten Text Recognition in Chinese. |
|
|
|
## Model description |
|
|
|
The model was trained using the PyLaia library on the [CASIA-HWDB1](http://www.nlpr.ia.ac.cn/databases/handwriting/Offline_database.html) document images. |
|
|
|
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 CASIA-HWDB2 training set. |
|
