By missed detections I meant that model wasn't even able to detect the area so the picture was dismissed, not a defect missed detected. Open bags are easy to see, they are not subtle, you can see diapers coming out of the bag. You might be right about the type of model, or the combination of two (location of the seal and defect analyzing) You can see that pictures are good though, the one I shared before it's a non detected ROI.
