# About |
|
|
|
This is a TrOCR model for medieval Humanistica. The base model was [microsoft/trocr-base-handwritten](https://huggingface.co/microsoft/trocr-base-handwritten). The model was then finetuned to Caroline: [medieval-data/trocr-medieval-latin-caroline](https://huggingface.co/medieval-data/trocr-medieval-latin-caroline). From a saved checkpoint, the model was further finetuned to Humanistica. |
|
|
|
The dataset used for training was [CATMuS](https://huggingface.co/datasets/CATMuS/medieval). |
|
|
|
The model has not been formally tested. Preliminary examination indicates that further finetuning is needed. |
|
|
|
Finetuning was done with finetune.py found in this repository. |

# Usage |
|
|
|
```python |
|
from transformers import TrOCRProcessor, VisionEncoderDecoderModel |
|
from PIL import Image |
|
import requests |
|
|
|
# load image from the IAM database |
|
url = 'https://huggingface.co/medieval-data/trocr-medieval-humanistica/resolve/main/images/humanistica-1.png' |
|
image = Image.open(requests.get(url, stream=True).raw).convert("RGB") |
|
|
|
processor = TrOCRProcessor.from_pretrained('medieval-data/trocr-medieval-humanistica') |
|
model = VisionEncoderDecoderModel.from_pretrained('medieval-data/trocr-medieval-humanistica') |
|
pixel_values = processor(images=image, return_tensors="pt").pixel_values |
|
|
|
generated_ids = model.generate(pixel_values) |
|
generated_text = processor.batch_decode(generated_ids, skip_special_tokens=True)[0] |
|
``` |
