MCESAN: A Modality Complementary Enhancement and Sparse Attention Network for Joint Hyperspectral and LiDAR Image Classification
Hyperspectral images (HSIs), with their hundreds of contiguous narrow bands, capture detailed physicochemical properties of land covers; LiDAR provides high-precision 3-D spatial and geometric structure, and the two modalities are highly complementary. However, differences in imaging mechanisms lead to insufficient cro...
