## Model Details


<!-- Provide a longer summary of what this model is. -->

TrOCR model fine-tuned on the [german_handwriting](https://huggingface.co/datasets/fhswf/german_handwriting). It was introduced in the paper [TrOCR: Transformer-based Optical Character Recognition with Pre-trained Models](https://arxiv.org/abs/2109.10282) by Li et al. and first released in [this repository](https://github.com/microsoft/unilm/tree/master/trocr).

- **Developed by:** [More Information Needed]
- **Model type:** Transformer OCR
- **Language(s) (NLP):** German
- **License:** [More Information Needed]
- **Finetuned from model [optional]:** [TrOCR_large_handwritten](https://huggingface.co/microsoft/trocr-large-handwritten)


## Uses

Here is how to use this model in PyTorch:

```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('TGrote11/testModel')
model = VisionEncoderDecoderModel.from_pretrained('TGrote11/testModel')
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]
```

## Bias, Risks, and Limitations

You can use the raw model for optical character recognition (OCR) on single text-line images of german handwriting.
