Research Paper Overview
FSG-Net: Frequency-Spatial Synergistic Gated Network for High-Resolution Remote Sensing Change Detection
Summary
FSG-Net addresses false alarms and semantic gaps in high-resolution remote sensing change detection by disentangling genuine changes from nuisance variations. It uses a Discrepancy-Aware Wavelet Interaction Module to reduce pseudo-changes in the frequency domain, a Synergistic Temporal-Spatial Attention Module to enhance true change regions spatially, and a Lightweight Gated Fusion Unit to integrate semantic and detailed features effectively. Validated on multiple benchmarks, it achieves state-of-the-art accuracy.
