DPG-CD: Depth-Prior-Guided Cross-Modal Joint 2D-3D Change Detection
Researchers introduce DPG-CD, a deep learning framework that detects both 2D semantic and 3D structural changes in urban environments by fusing multi-temporal satellite imagery with Digital Surface Model data. The method addresses the challenge of combining different data modalities to enable high-frequency urban monitoring and disaster assessment without requiring expensive frequent 3D data collection.
