Boundary-Aligned Contribution Routing for Robust Optical--SAR Object Detection
Haifa Zhang, Yijing Wang, Haoyu Wang +2
Optical imagery provides rich appearance cues, whereas synthetic aperture radar (SAR) offers observations that are less sensitive to illumination and weather, making optical--SAR f…
DeGuNet: Depth-Guided Ultra-Compact Backbones for Efficient LiDAR-Camera 3D Detection
Haifa Zhang, Yijing Wang, Peixi Peng +1
In autonomous driving perception, the fusion of LiDAR and camera modalities has become the dominant paradigm for 3D object detection. However, current multi-modal frameworks heavil…
Can BEV Perception Gracefully Degrade under Sensor Failures?
Haifa Zhang, Yijing Wang, Haoyu Wang +2
Despite the remarkable success of multi-modal bird's-eye view (BEV) perception in autonomous driving, current systems exhibit a critical vulnerability: existing fusion mechanisms a…
AutoInst: Automatic Instance-Based Segmentation of LiDAR 3D Scans
Cedric Perauer, Laurenz Adrian Heidrich, Haifan Zhang +3
Recently, progress in acquisition equipment such as LiDAR sensors has enabled sensing increasingly spacious outdoor 3D environments. Making sense of such 3D acquisitions requires f…
