Usage

python

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

# Load model and processor
processor = TrOCRProcessor.from_pretrained("anuashok/ocr-captcha-v3")
model = VisionEncoderDecoderModel.from_pretrained("anuashok/ocr-captcha-v3")

# Load image
image = Image.open('path_to_your_image.jpg').convert("RGB")
# Load and preprocess image for display
image = Image.open(image_path).convert("RGBA")
# Create white background
background = Image.new("RGBA", image.size, (255, 255, 255))
combined = Image.alpha_composite(background, image).convert("RGB")

# Prepare image
pixel_values = processor(combined, return_tensors="pt").pixel_values

# Generate text
generated_ids = model.generate(pixel_values)
generated_text = processor.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(generated_text)
