Model Architecture
WeatherRemover adopts a UNet-like structure, enhanced with a multi-scale pyramid vision Transformer (MS-PVT) and channel-wise attention. This design ensures that the model can handle varying input image sizes and process features across multiple scales effectively. The integration of linear spatial reduction within the Transformer minimizes computational demands while preserving crucial information. This architectural choice is key to the model's ability to balance high-quality restoration with operational efficiency across diverse weather conditions.
Performance Gains
The model consistently achieves state-of-the-art performance in single-weather removal tasks (rain, snow, fog) and robust performance in multi-weather scenarios. Notably, it delivers a PSNR of 32.26 dB for desnowing (Snow100K-L) and 32.99 dB for raindrop removal (Raindrop-A), outperforming many existing models. The ability to restore fine-grained details and reconstruct underlying scenes accurately, even in challenging conditions, translates into clearer visual data for enterprise applications.
Efficiency Metrics
Despite its superior restoration quality, WeatherRemover is designed to be lightweight and efficient. It boasts a parameter count of 24.3M and inference times ranging from 0.05s to 0.16s across different datasets (RTX 4090). Compared to models like Restormer, it achieves a 49% reduction in MACs, making it highly suitable for real-time applications and environments with constrained computational resources, such as autonomous vehicles or surveillance systems.
Gating Mechanism
A novel gating mechanism is strategically incorporated into both the downsampling process and the feed-forward network (GFN). This mechanism selectively retains essential information, minimizing the interference of redundant data and refining information processing. It adaptively selects crucial data, ensuring superior restoration and maximizing efficiency. The GFN, while adding about 3.66M parameters, significantly boosts restoration performance, justifying its computational cost through enhanced output quality.
Challenges & Future Work
While effective, the model currently faces challenges in handling dense occlusions and low-resolution restoration during extreme weather, and its multi-weather performance, though strong, is not yet on par with single-weather specialists. Future work aims to optimize the GFN's computational efficiency by replacing convolutions with pooling layers, integrate a global attention mechanism for better contextual feature integration, and implement continual learning strategies to adapt to new weather conditions without catastrophic forgetting, ensuring broader applicability and robustness.
