Core Innovation: Prior-Guided Degradation Removal
At the heart of this research is a novel prior-guided dynamic degradation removal mechanism. Traditional image fusion often struggles with real-world scenarios marred by haze, low light, or overexposure. This AI integrates physical-parameter-based pre-enhancement to adaptively filter out deleterious interference before fusion. This preliminary enhancement stabilizes input images, significantly improving the quality of the fused output and enabling robust performance in challenging conditions.
Architecture: Sparse Mixture-of-Experts (MoE)
The system employs a sophisticated sparse Mixture-of-Experts (MoE) architecture, guided by degradation descriptions generated by large visual-language models (e.g., CLIP). This dynamic network structure allows the model to flexibly manage diverse degradation information. Instead of a one-size-fits-all approach, specific 'experts' are activated based on the input image's degradation severity, ensuring optimal processing for varying environmental challenges. This enhances adaptability and computational efficiency.
Loss Function: Multi-Task Integration
To further optimize fusion performance, a composite loss function has been devised, integrating pixel-level loss, gradient loss, reconstruction loss, and mutual information loss. This multi-task approach ensures that the fused images not only retain fine-grained details and structural fidelity but also maintain high modal discrimination. This comprehensive loss mechanism is crucial for producing clear, informative, and visually consistent fused images across all degradation types.

Clear Fused Output
| Metric | Proposed Method | TextIF | SuperFusion |
|---|---|---|---|
| AG | 10.7784 | 8.8831 | 4.3293 |
| EN | 7.7200 | 7.4173 | 7.1332 |
| SF | 31.9825 | 28.7048 | 16.2125 |
| SD | 62.3594 | 49.4001 | 42.0680 |
| VIF | 0.9312 | 0.6492 | 0.6984 |
| MI | 2.7019 | 2.4305 | 3.7571 |
| The proposed method consistently outperforms competitors in critical metrics like Average Gradient (AG) and Spatial Frequency (SF) on the LLVIP dataset, demonstrating superior clarity and detail retention in low-light conditions. While MI is slightly lower than SuperFusion, the overall balance of metrics indicates a more comprehensive performance. | |||
Enhanced Night Vision in Surveillance
Scenario: A surveillance camera monitors a bridge at night, a scenario where insufficient brightness renders visible images almost useless. Traditional fusion methods struggle to restore clarity, leading to blurry or underexposed results.
Solution: The AI's physics-parameter pre-enhancement and MoE architecture dynamically adapt to the extreme low-light. It accurately restores scene brightness and extracts fine-grained pedestrian information from infrared, merging it with the faint visible details.
Outcome: The fused image clearly shows pedestrians on a zebra crossing and legible text on a pole, critical details missed by other methods. This significantly improves real-time threat detection and situational awareness in low-light surveillance.
