Welding Defect Object Detection

2,028 annotated images of welds for defect detection, in both YOLO and COCO formats. Three classes:

id (YOLO / COCO)	name
0 / 1	Bad Weld
1 / 2	Good Weld
2 / 3	Defect

Splits

split	images	annotations
train	1,619	4,583
valid	283	802
test	126	301

COCO conversion notes

The coco/ jsons were generated from the YOLO labels with the flux YOLO→COCO converter:

bbox = [x_min, y_min, width, height], float pixels
boxes clamped to image bounds
category ids are one-based (YOLO class 0 → COCO id 1)
annotation count parity verified: 5,686 YOLO label lines → 5,686 COCO annotations
