Dual energy X-ray imaging based material discrimination technique was developed to discriminate and identify the materials types (namely Organic, inorganic and metal) in a passenger luggage bag based on atomic number and density values. The developed technique integrated with X-ray Baggage Inspection Systems (XBIS) can be deployed in airports, shopping malls, corporate buildings, hotels and railway stations etc. for passenger luggage inspection to identify concealed materials & substances present inside parcels. XBIS combines the extensive benefits of the scanning process with state-of-the-art image processing.
Salient technical features
- Dual energy image fusion
- Determination of atomic number and density of scanned material items
- Based on atomic number, the material items are labeled and displayed as 3-color & 6-color material discrimination images under different categories namely organic, inorganic and metals
- Separate buttons are provided for image processing functionalities such as image loading, image fusion, 3-color image, 6-color image, density image, organic stripping, inorganic stripping and metal detection.
- Two identical materials of similar thickness belonging to different material types can be segregated.
- Display of density image
- High density region alarm (red alert)
- Algorithm implementation as DLL library
- Hardware security enabled X-ray software
Benefits
- This technology enables industry collaborator M/s.Krystalvision to upgrade their X-ray Baggage scanning machine to next level of commercialization with additional features and cost benefits.
- It has wide application in security and surveillance based Dual-energy X-ray scanning systems.
The know-how was transferred to M/s. Krystalvision Image Systems Pvt. Ltd., Pune, Maharashtra. About 24 scanners were fabricated and installed throughout India by the licensee during 2017-18.
