IGECNet: An Interaction-Guided Multimodal Fusion Network With Elevation Constraint for Remote Sensing Semantic Segmentation (opens in new tab)

Semantic segmentation of multimodal remote sensing images plays a crucial role in geospatial analysis. However, existing methods often struggle to effectively integrate spatial–spectral and geometric–geographic information, capture multiscale contextual features, and preserve the fine-grained boundaries of geo-objects. To address these challenges, we propose an interaction-guided multimodal fusion network with elevation constraint, referred to as IGECNet. The proposed network comprises four k...
