An Improved YOLOv8n-Based Algorithm for Body-in-White Spot-Weld Defect Detection
In automotive body-in-white (BIW) inspection, small spot-weld defects can be obscured by metal-surface reflections and by the similar morphology of normal and defective welds. This study proposes FasterNet-Context-Guided Block-C2f-CNCM YOLO (FCC-YOLO), an improved YOLOv8n detector that applies stage-wise feature compen...
