"Gong is leading an international team of researchers to develop a next-generation CCTV system, called Samurai, which is capable of identifying and tracking individuals that act suspiciously in crowded public spaces. It uses algorithms to profile people's behaviour, learning about how people usually behave in the environments where it is deployed. It can also take changes in lighting conditions into account, enabling it to track people as they move from one camera's viewing field to another.
Samurai is designed to issue alerts when it detects behaviour that differs from the norm, and adjusts its reasoning based on feedback. So an operator might reassure the system that the person with a mop appearing to loiter in a busy thoroughfare is no threat. When another person with a mop exhibits similar behaviour, it will remember that this is not a situation that needs flagging up." Sheesh.
