# ZeroIG: Zero-Shot Illumination-Guided Joint Denoising and Adaptive Enhancement
🎉 **CVPR 2024** | Zero-shot low-light image enhancement without training data
## 🚀 Quick Start
Upload a low-light image and get an enhanced version in seconds! No training required.
## 📖 About
This space implements **ZeroIG**, a novel zero-shot method for jointly denoising and enhancing low-light images. The method is completely independent of training data and noise distribution.
### ✨ Key Features
- **Zero-shot**: No training data required
- **Joint processing**: Simultaneous denoising and enhancement
- **Illumination-guided**: Smart adaptive enhancement
- **Prevents artifacts**: Avoids over-enhancement and localized overexposure
- **Real-time**: Fast processing for practical use
### 🔬 How it Works
1. **Illumination Estimation**: Extracts near-authentic illumination from the input
2. **Adaptive Enhancement**: Applies different enhancement levels based on pixel intensity
3. **Joint Denoising**: Removes noise while preserving image details
4. **Artifact Prevention**: Prevents common enhancement artifacts
## 📊 Performance
ZeroIG outperforms state-of-the-art methods on standard benchmarks while requiring no training data.
## 🎯 Use Cases
- **Photography**: Rescue underexposed photos
- **Security**: Enhance surveillance footage
- **Mobile**: Real-time camera enhancement
- **Medical**: Improve low-light medical imaging
- **Astronomy**: Enhance night sky photography
## 🖼️ Supported Formats
- JPEG, PNG, TIFF, BMP
- RGB color images
- Various resolutions (optimized for typical photo sizes)
## ⚡ Tips for Best Results
- Works best with real low-light photos (not artificially darkened)
- Indoor and outdoor scenes both supported
- Processing time varies with image size (typically 10-30 seconds)
