FRA-YOLO: Frequency-guided receptive-field adaptation for occluded ship detection in complex nearshore backgrounds

Detecting ships in complex nearshore scenes is difficult because occlusion, dense interactions, small apparent scale, and structured background textures cause missed detections, false alarms, and inaccurate localization. We propose FRA-YOLO, a compact YOLO11n-based detector that...
