模型簡介

字符錯誤率（CER）：0.035。這是一個用於處理CATMuS數據集中中世紀手寫文字的TrOCR模型。基礎模型採用了 microsoft/trocr-base-handwritten。訓練使用的數據集為 CATMuS。該模型尚未經過正式測試，初步檢查表明可能需要進一步微調。微調操作可使用本倉庫中的 finetune.py 腳本完成。

使用示例

from transformers import TrOCRProcessor, VisionEncoderDecoderModel
from PIL import Image
import requests

# 從IAM數據庫加載圖像
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]
