Launched a state project to develop an AI gait analysis platform for criminal investigations

SEOUL — South Korea has launched a state project to develop an advanced gait analysis system for scientific crime investigations, based on artificial intelligence and deep learning, nearly nine years after the demonstration of related technology by a British expert who played a crucial role in the capture of a criminal.

In 2013, a criminal fled after throwing a firebomb at the home of a former intelligence chief in Seoul, but investigators failed to identify him due to poor image quality closed-circuit television (CCTV) cameras. Police have sought the help of Hayden Kelly, a British consultant podiatrist who is listed in the Guinness Book of World Records as the first person to use gait analysis in a court case.

Based on Kelly’s analysis, the investigation was complete. Since then, the National Police Agency (NPA) has tried to master Kelly’s skills in cooperation with researchers, but the technological development failed for various reasons. The Ministry of Science and ICT said on March 28 that it had approved a joint project with the police to develop an AI gait analysis system.

To improve the reliability and accuracy of an investigative technique that tracks suspects in walking form, the ministry said CCTV footage would be combined with biomechanical data to quickly select and track criminal suspects and missing persons. . For commercialization, a university research team will work with SEO, a private company that develops video surveillance systems using technologies such as deep learning.

Gait analysis is commonly used in sports biomechanics to help athletes run more efficiently and to identify postural or movement-related issues in injured individuals.
