xModel-KD: Cross-modal Knowledge Distillation for 3D Scene Perception using LiDAR arXiv:2605.30111v1 Announce Type: new Abstract: Point cloud segmentation is a fundamental task in 3D scene understanding. Its progress is constrained by the high cost and time required for dense 3D annotations, making labeled samples difficult to obtain. Beyond annotation scarcity, different sensing modalities face inherent limitations. 2D images provide rich texture and appearance cues, yet they lack explicit dep
