Density-Aware Tree–Graph Cross-Message Passing for LiDAR Point Cloud 3D Object Detection
LiDAR-based 3D object detection is fundamental in autonomous driving but remains challenging due to the irregularity, unordered nature, and non-uniform density of point clouds. Existing methods primarily rely on either graph-based or tree-based representations: Graph-based models capture fine-graine...
