✨ AuraSR: GAN Super-Resolution for Images 🖼️

AuraSR is a powerful GAN-based super-resolution tool that enhances image clarity and size. Based on the GigaGAN concept, it excels with specific image types.

🎨 Features

• Upscales PNG, lossless WebP, and high-quality JPEG XL (90+) images
• Supports scale factors of 2x, 4x, 8x, 16x, and 32x
• Efficient processing with adjustable batch sizes

⚠️ Important Notes

AuraSR is powerful but has some limitations:

1. Best results with PNG, lossless WebP, and high-quality JPEG XL (90+)
2. Sensitive to compression artifacts
3. No built-in error correction for image imperfections
4. Ideal for upscaling AI-generated or high-quality uncompressed images

🛠️ Usage

Input Parameters

• image: The input image to upscale (PNG, WebP, or high-quality JPEG XL)
• scale_factor: Upscaling factor (2, 4, 8, 16, or 32)
• max_batch_size: Number of image tiles processed simultaneously (default: 1)

Example

import replicate

output = replicate.run(
    "zsxkib/aura-sr:<VERSION>",
    input={
        "image": open("path/to/your/image.png", "rb"),
        "scale_factor": 4,
        "max_batch_size": 4
    }
)
print(output)
