PC$^2$-AD: Point Cloud Upsampling to Safeguard 3D Anomaly Detection with Resolution-constrained Edge Devices

Low-cost and low-resolution sensors used in edge deployments can produce test point clouds that are substantially sparser than the normal training data. This train-test sampling-resolution gap changes the local geometry available to a 3D anomaly detector. We propose PC$^2$-AD, a point cloud upsampling framework that co...

FTTrack: RGB-T Tracking With Frequency-Adaptive Fusion and Temporal Enhancement

RGB-T tracking exploits complementary information from RGB and thermal infrared (TIR) modalities to achieve robust object tracking. Mainstream approaches exhibit limitations in two critical aspects: inadequate cross-modal feature fusion and insufficient temporal modeling, resulting in performance degradation during cha...
