Propagate and Calibrate: Real-Time Passive Non-Line-of-Sight Tracking
2023 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2023 Non-line-of-sight (NLOS) tracking has drawn increasing attention in recent years, due to its ability to detect object motion out of sight. Most previous works on NLOS tracking rely on active illumination, e.g., laser, and suffer from high cost and elaborate experimental conditions.
