Among these problems, inspection systems for continuous feed production (named as “web-inspection”), are those that raise the main challenges for the researchers exceeding the current systems capacity. Manual inspection, that is still being used in many cases, does not allow to reach detection guarantees, accuracy, robustness and a high volume that are required in webbased manufacturing.
