SFC-DETR: An Asymmetric Spatial-Frequency Intervention Paradigm for Dense Aerial Object Detection
Unmanned aerial vehicle (UAV) object detection struggles with weak and tiny targets due to extreme viewing angles and environmental clutter. While the Real-Time Detection Transformer (RT-DETR) offers end-to-end efficiency, its macroscopic pooling and global attention mechanisms intrinsically discard the local spatial c...
