Trocr Medieval Castilian Hybrida

🚀 中世紀卡斯蒂利亞語Hybrida字體TrOCR模型

本項目是一個針對中世紀卡斯蒂利亞語，特別是Hybrida字體的TrOCR模型。該模型能有效識別中世紀卡斯蒂利亞語Hybrida字體的圖像文本，為相關歷史文獻的數字化處理提供了有力支持。

🚀 快速開始

本模型是用於中世紀卡斯蒂利亞語的TrOCR模型，具體針對Hybrida字體。基礎模型採用了 microsoft/trocr-base-handwritten，之後針對卡羅琳字體進行了微調：medieval-data/trocr-medieval-latin-caroline。從保存的檢查點開始，模型進一步針對卡斯蒂利亞語Hybrida字體進行了微調。

訓練使用的數據集是 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。

微調使用的是本倉庫中的 finetune.py 文件。

💻 使用示例

基礎用法

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-castilian-hybrida/resolve/main/images/hybrida-1.png'
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]
