Abstract: Highlights•Features within an object are aggregated to reduce communication volume.•A sparse 3D cooperation module is proposed to enhance agent interaction.•A bounding box restoration module is introduced to recover the undetected boxes.•SparseComm demonstrates state-of-the-art results on the DAIR-V2X and V2XSet datasets.
