Parameter-efficient small object detection via P2 head co-design for UAV remote sensing images

Small object detection from UAVs is fundamentally limited by the resolution loss imposed by standard P3–P5 feature pyramids, which leave nearly 47% of VisDrone annotations under-resolved. We address this by co-designing a stride-4 P2 detection head with shared Distribution Focal Loss and channel scaling, reducing param...
