CER: 0.035
This is a TrOCR model for medieval scripts in the CATMuS Dataset. The base model was microsoft/trocr-base-handwritten.
The dataset used for training was CATMuS.
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
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-print/resolve/main/images/print-1.png'
image = Image.open(requests.get(url, stream=True).raw).convert("RGB")
processor = TrOCRProcessor.from_pretrained('medieval-data/trocr-medieval-base')
model = VisionEncoderDecoderModel.from_pretrained('medieval-data/trocr-medieval-base')
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]
