Researchers have developed a novel framework for weakly supervised radar scene flow estimation, addressing the challenge of limited ground-truth data. This new method utilizes images and odometry for auxiliary supervision, avoiding the need for costly LiDAR sensors or complex multi-task architectures. The approach incorporates instance-aware self-supervised losses derived from 2D tracking and segmentation, along with a rigid static loss for stationary regions. Experiments on the View-of-Delft dataset show superior performance compared to existing cross-modal supervised and fully supervised methods. AI
