FocalComm: Hard Instance-Aware Multi-Agent Perception (WACV 2026)
Pretrained checkpoints for FocalComm, a collaborative perception framework that exchanges hard-instance-oriented features among connected agents via progressive Hard Instance Mining (HIM) and Query-guided Adaptive Feature Fusion (QAFF).
Checkpoints
| File | Dataset | Config | AP@0.3/AP@0.5 |
|---|---|---|---|
focalcomm_v2xreal/net_epoch50.pth |
V2X-Real (vehicle-centric) | FocalComm 3-stage HIM, epoch 50 | Car 91.6/88.4, Pedestrian 53.2/26.1, Truck 50.4/47.2, Overall 65.1/53.9 |
focalcomm_dairv2x/net_epoch50.pth |
DAIR-V2X | FocalComm, epoch 50 | Vehicle 73.3/66.4 |
Each checkpoint directory includes the exact training config.yaml. The DAIR-V2X checkpoint reproduces the paper result exactly; the V2X-Real checkpoint is the final epoch of the paper's training run (within ~2 mAP of the paper's Table 1 row).
Usage
pip install -U huggingface_hub
hf download scdrand23/FocalComm --local-dir checkpoints
python focalcomm/tools/inference.py --model_dir checkpoints/focalcomm_v2xreal --fusion_method intermediate
