# trocr-old-russian
## Info
The model is trained to recognize printed texts in Old Russian language
- Use microsoft/trocr-small-printed as base model for fine-tune.
- Fine-tune on 636k text images from dataset: https://huggingface.co/datasets/nevmenandr/russian-old-orthography-ocr

## Usage
### Base-usage
```python
from PIL import Image
from transformers import TrOCRProcessor, VisionEncoderDecoderModel

hf_model = VisionEncoderDecoderModel.from_pretrained("Serovvans/trocr-prereform-orthography")

image = Image.open("./path/to/your/image")

processor = TrOCRProcessor.from_pretrained("microsoft/trocr-base-printed")
pixel_values = processor(images=image, return_tensors="pt").pixel_values

generated_ids = hf_model.generate(pixel_values)
generated_text = processor.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(generated_text)
```
## Usage for recognizing the book
```python
```

## Metrics on test
- CER (Char Error Rate) = 0.095
- WER (Word Error Rate) = 0.298
