+## 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)
