FAD-Net: Frequency-Domain Amplitude-Phase Decoupling Network for Optical-Elevation Remote Sensing Segmentation (opens in new tab)

Multimodal remote sensing semantic segmentation leverages multisource information for fine-grained scene analysis. However, due to the inherent limitations of spatial-domain representations, achieving effective feature interaction and reconstruction remains challenging. In this article, we propose the frequency-domain amplitude-phase decoupling network (FAD-Net). To resolve the fusion bottleneck caused by heterogeneous feature misalignment in the spatial domain, we design the multimodal Mona ...
