GED-YOLOv5: an improved YOLOv5 model for weld defect detection via gather-and-distribute mechanism and transfer learning

Small-sample visible-light weld inspection is difficult because circular metal surfaces introduce specular reflection, low local contrast, weld-like background texture, and elongated defects that may occupy only a small region after image resizing. This paper proposes GED-YOLOv5, a task-adapted YOLOv5 detector for circ...
