Two-stage 3D object detection architecture via integrated attention mechanism and voxel aggregation
This paper presents spatial-channel attention guided with Gumbel SUBSET SAMPLING and context fusion RCNN (SCAGCF-RCNN) as an incremental engineering improvement of the PV-RCNN two-stage point–voxel detection baseline, demonstrating competitive detection accuracy and robustness in challenging scenarios.
