Daniil-Domino/trocr-base-ru-dialectic-stackmix

Russian Dialectic HTR using TrOCR

The TrOCR-base-ru model was fine-tuned on synthetic datasets generated using StackMix method and based on various fonts.

For more information, check out the GitHub repository.

Model description

TrOCR-base-ru was fine-tuned for Handwritten Russian Text Recognition in dialectological cards. The model was trained for a total of 20 epochs with a batch size of 16 using dual NVIDIA T4 GPUs. The fine-tuning process took approximately 28 hours.

Example Usage

# Load libraries
from transformers import TrOCRProcessor, VisionEncoderDecoderModel
import matplotlib.pyplot as plt
from PIL import Image


# Load image
img_path = 'path/to/image'
image = Image.open(img_path).convert("RGB")

# Load model and processor
model_name = "Daniil-Domino/trocr-base-ru-dialectic-stackmix"
processor = TrOCRProcessor.from_pretrained(model_name)
model = VisionEncoderDecoderModel.from_pretrained(model_name)

# Preprocess and run inference
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]

# Output result
print(generated_text)

# Display input image
plt.axis("off")
plt.imshow(image)
plt.show()
