# Himanis handwritten text recognition
|
16 |
+
|
17 |
+
This model performs Handwritten Text Recognition in French on medieval documents.
|
18 |
+
|
19 |
+
## Model description
|
20 |
+
|
21 |
+
The model was trained using the PyLaia library on two medieval datasets:
|
22 |
+
* [Himanis](https://demo.arkindex.org/browse/5000e248-a624-4df1-8679-1b34679817ef?top_level=true&folder=true) (French)
|
23 |
+
* [HOME Alcar](https://demo.arkindex.org/browse/46b9b1f4-baeb-4342-a501-e2f15472a276?top_level=true&folder=true) (Latin)
|
24 |
+
|
25 |
+
For training, text-lines were resized with a fixed height of 128 pixels, keeping the original aspect ratio.
|
26 |
+
|
27 |
+
An external 6-gram character language model can be used to improve recognition. The language model is trained on the text from the Himanis training set.
|
28 |
+
|
29 |
+
## Evaluation results
|
30 |
+
|
31 |
+
The model achieves the following results:
