The algorithms that go into your luggage screening at airports

When you check in your baggage for a flight, it must be screened before it is allowed on the plane. Baggage screening detects threats within luggage and personal belongings by X-ray analysis as they pass along a conveyor belt. Hold-baggage and passenger screening systems are capable of detecting contraband materials, narcotics, explosives and weapons.

Millions of bags, boxes and parcels pass through airport security every year. Baggage screening needs to be highly efficient and reliable to avoid delays. Hazard-detection systems have to comply with strict standards, without impacting throughput. Hold-baggage screening devices are capable of inspecting thousands of bags per hour.

Increasing security threats have led to higher needs for detection and for increased efficiencies. From next year, airport screening systems for hand baggage must have detection levels similar to medical CT (computed tomography) scans.
