Self-Supervised Diffusion-Based Scene Flow Estimation and Motion Segmentation With 4D Radar
RA-L 2025
Scene flow estimation (SFE) and motion segmentation (MOS) using 4D radar are emerging yet challenging tasks in robotics and autonomous driving applications. Existing LiDAR- or RGB-D-based point cloud processing methods often deliver suboptimal performance on radar data due to radar signals' highly s
