Figure 4. Ten illustrative images from the private container defect dataset with ground-truth annotations, arranged in two rows of five. Cyan contours indicate container-surface mask boundaries; colored rectangles indicate defect annotations (orange: Deformation; green: Hole; magenta: Repair Patch; red: Contamination). The examples show variation in defect scale and shape, illumination, viewpoint, and background clutter. They are selected illustrations rather than a statistically representative sample.
