A biometric solution linked to machine learning and CCTV systems could track an individual or object anywhere in a city, and potentially within minutes, according to a Singaporean startup.The company, Xjera Labs, has created a system that can detect individuals, vehicles and objects from video footage with a 97% accuracy, based on a database containing 20,000 people whose faces have been captured on CCTV.A report in IBtimes details how the company has defeated current limitations in AI and video analytics.Xjera Labs says it has made this possible by building incredibly dense 52-layer neural networks and having multiple networks, so that it is possible for the system to produce the answer to a single attribute question like, “How many men have brown hair?” within 200 milliseconds. “If the police want to find someone, then they want a very fast response. With our system, we are constantly doing facial indexing in real-time on CCTV camera footage. The footage is uploaded to the cloud by our customers and we process the data,” Xjera Labs' founder and CTO Ethan Chu told IBTimesUK at the Innovfest Unbound 2017 event in Singapore.”We use part-based representation and different layers in the neural network focus on different attributes. We have basic layers that describe the subject in general, ie. the subject's shape, texture and colours. Then other layers are split into different attributes to describe things in more detail, so if we want to know if someone is wearing glasses, only the layers that concern detecting the head will be used to search for that.”The start-up has developed three products – XHound, which is able to locate a person or vehicle of interest; XIntelligence, which is able to count people in a crowd in high density indoor and outdoor locations; and XTransport, which can count and classify cars on highways, as well as detecting illegal driving and traffic accidents.Xjera Labs says that its products are already being used by the Singapore police, as well as by large corporations that run theme parks, conveyor belt sushi restaurants and even schools in China.
