+# About
+
+This is a TrOCR model for medieval Castilian, specifically the Hybrida script. 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 Textualis.
+
+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://fki.tic.heia-fr.ch/static/img/a01-122-02-00.jpg'
+image = Image.open(requests.get(url, stream=True).raw).convert("RGB")
+
+processor = TrOCRProcessor.from_pretrained('medieval-data/trocr-medieval-castilian-hybrida')
+model = VisionEncoderDecoderModel.from_pretrained('medieval-data/trocr-medieval-castilian-hybrida')
+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]
