With millions of smart cameras and IoT devices in our customers’ home, Xfinity Home is becoming a leading platform to improve our customers’ safety and security. Our teams are using computer vision and deep learning techniques to understand videos and sensor data from our customers’ home, to improve user experience by delivering relevant events and customizing event notification. We detect and recognize objects, identify region of interest and recognize activities by exploring the spatial-temporal relationship among object, place and actions. We built an efficient, scalable and robust video and data analytics platform for smart home applications. I will discuss the challenges of data analytics, summarize our recent efforts, and identify future opportunities for smart home.
