IB-HFN: Information Bottleneck-Driven SAR-Optical Fusion Network for High-Fidelity Cloud Removal
Researchers have developed a new network called IB-HFN to improve the removal of clouds from optical remote sensing images using synthetic aperture radar (SAR) data. This method addresses limitations in existing techniques that can introduce SAR speckle noise and lead to over-smoothed results. IB-HFN uses a dual-stream backbone and a novel fusion module to better preserve modality-specific information and suppress noise while maintaining texture and spectral fidelity. Experiments show that IB-HFN outperforms current methods on the SEN12MS-CR dataset. AI
