Usage Examples and API Overview

Real-ESRGAN provides a straightforward API for image restoration. Here’s a basic example of how to use the library:

from RealESRGAN import RealESRGAN

# Initialize the model
model = RealESRGAN()

# Load an image
image = model.load_image('path/to/image.jpg')

# Restore the image
restored_image = model.restore(image)

# Save the restored image
model.save_image(restored_image, 'path/to/restored_image.jpg')

This simple code snippet demonstrates how to load an image, restore it using Real-ESRGAN, and save the output.
