# POPP handwritten text recognition
|
16 |
+
|
17 |
+
This model performs Handwritten Text Recognition on French census documents.
|
18 |
+
|
19 |
+
## Model description
|
20 |
+
|
21 |
+
The model was trained using the PyLaia library on the [POPP generic](https://github.com/Shulk97/POPP-datasets/).
|
22 |
+
|
23 |
+
For training, text-lines were resized with a fixed height of 128 pixels, keeping the original aspect ratio.
|
24 |
+
|
25 |
+
An external 6-gram character language model can be used to improve recognition. The language model is trained on the text from the POPP training set.
|
26 |
+
|
27 |
+
## Evaluation results
|
28 |
+
|
29 |
+
The model achieves the following results:
