Low Threat Detection Rates

Image interpretation relies heavily on human perception and decision-making. Failure rates and false alarms are high, due to the disruptive environment and other external variables such as the pressure to perform or tiredness. Majority of the scanned bags do not contain threats, which can result in complacency as time passes. While many actual threats are missed because of image complexity and the difficulty posed by the object’s viewing angle, the list of prohibited items continues to grow, challenging the human operator even more.

Slow Throughput

Long and slow-moving queues to security screening frustrate airline passengers. Separating electronics and liquids prior to screening helps the image interpretation task, but increases the time passengers spend at the checkpoint. In addition, up to 30% of the bags are flagged for manual inspection, prolonging the process further. Allowing passengers to keep electronics and liquids inside their bags and reducing the number of items erroneously flagged for manual search, would dramatically increase throughput.
