RFM-UNet: Hybrid Frequency–Mamba UNet for Remote-Sensing Road Extraction

Road-network extraction from very high-resolution (VHR) remote-sensing imagery remains a challenging task owing to the structural sparsity, topological complexity, and severe occlusions of road networks. Conventional graph-based approaches preserve topological consistency yet incur considerable computational overhead,...

CoastMamba: A Boundary-Enhanced Mamba Framework for Sea–Land Segmentation in Optical Remote Sensing Imagery

To mitigate background interference and structural ambiguity, a grouped coordinate Mamba block is designed to generate adaptive gating masks for effective feature recalibration and selective boundary emphasis, and a Frequency-Domain Boundary-Enhanced Module is introduced to jointly leverage spatial and frequency repres...
