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 Classification Method Based on Adaptive Multi-Scale Fusion for Long-tailed Multispectral Point Clouds
TianZhu Liu, BangYan Hu, YanFeng Gu +2
Multispectral point cloud (MPC) captures 3D spatial-spectral information from the observed scene, which can be used for scene understanding and has a wide range of applications. Ho…
