See Through Solutions aims for global markets with a solution that modernizes and speeds up security screening. Its terahertz-based thermal camera can accurately and discreetly detect objects hidden under clothing. The solution removes the need for manual inspections, helping large numbers of people move more quickly through locations such as border crossings, transport hubs and large public events.
In the company’s technology, the detection of threat objects, such as weapons, plastic explosives and drugs, is automated using artificial intelligence. However, training suitable AI models for this purpose is challenging: collecting sufficiently large and diverse training datasets from terahertz images is labor-intensive and cannot cover every real-world scenario.
Aalto University computer science student Syed Ashraf developed an AI solution for See Through Solutions in his master’s thesis, improving the detection of threats hidden under clothing.
“In my thesis, I examined a key challenge in terahertz imaging: the lack of high-quality and diverse training data,” Ashraf explains.
“In the project, synthetic data was generated and tested to see how it affects the model’s ability to make accurate predictions,” says Perttu Kajatkari, Software Manager at See Through Solutions, who served as the thesis advisor.
The thesis was funded by the Finnish AI Region (FAIR EDIH) initiative, which supports the adoption of AI in SMEs. Aalto University is one of the ten partners in the FAIR network.
“FAIR brings together augmented reality, artificial intelligence and their industrial applications—exactly the areas our technology builds on. In a way, our camera functions as a ‘sixth sense’, allowing us to see things that humans normally cannot,” says Aarne Oja, CEO of See Through Solutions.
