Advanced Surveillance Software

China has introduced a new surveillance software in Beijing and Shanghai which authorities say can identify people from their walking style, even with their backs turned and faces hidden. The software takes a digital model of a person’s silhouette and walking style from surveillance video and then creates a 3D model of their style and stance. The CEO of Watrix, the company behind the technology, promises to fix problems with facial recognition software, which needs close-up, high-quality images to identify people.
