S3D-Mosaic: Subgradient-Guided Cross-Band Structure Transfer for Spectral Demosaicing
Weiqiang Zhao, Xian Li, Yuzhe Gui +2
Multispectral filter array (MSFA) imaging enables snapshot spectral acquisition, but its per-band sparse sampling causes severe spatial aliasing. Although missing spatial structure…
PF-Trans: Physics-Embedded Frequency-Aware Transformer for Spectral Reconstruction
Yuzhe Gui, Tianzhu Liu, Yanfeng Gu +1
Snapshot Broadband Filter Array (BFA) imaging provides high light throughput for spectral reconstruction but introduces severe spectral aliasing due to complex modulation. Current…
Multi-Angular Reflectance Anisotropy Observed from UAV Multispectral Imagery
Zhenqiang Qin, Chenguang Dai, Min Wang +1
UAV multispectral imagery naturally contains multi-angular observations due to low flight altitude and wide field-of-view imaging, which may introduce geometry-driven radiometric v…
CAMF-Det: Closure-Aware Multimodal Fusion for LiDAR-Camera 3D Object Detection on UAV Platforms
Yanze Jiang, Yanfeng Gu, Xian Li
Multimodal 3D object detection based on LiDAR and cameras has demonstrated excellent performance in ground-vehicle scenarios, but has not been explored for Unmanned Aerial Vehicle…
Illumination-Invariant Anomaly Detection for Sub-Canopy UAV Multispectral Point Clouds
Likun Chen, Yanfeng Gu, Xian Li
Unmanned Aerial Vehicle (UAV) multispectral point clouds (MPC) provide high-dimensional spatial-spectral data for sub-canopy target detection; however, their efficacy is significan…
An Enhanced Geometric-Spectral Feature Learning Framework for Airborne Multispectral Point Cloud Classification
Xian Li, Yanfeng, Gu Linghua Xu +1
Multispectral point cloud (MPC) is composed of 3D spatial-spectral information, which holds tremendous potential for accurate land-cover classification. However, the representation…
Sub-Footprint Effect Correction in FW-LiDAR Point Clouds via Intra-Footprint Target Unmixing
Zhen Xiao, Yanfeng Gu, Xian Li
Sub-footprint target mixing within a laser footprint significantly increases LiDAR intensity uncertainty, especially in complex environments where heterogeneous materials inside on…
