Feasibility of Indoor Frame-Wise Lidar Semantic Segmentation via Distillation from Visual Foundation Model

The paper frames the work as perceptionPerception & SensingPerceptionThe process of turning raw sensor data into useful understanding of the world.. Start here because it defines what success means and which assumptions the rest of the method inherits.
