Abstract
Methods and systems for identifying persons utilizing a camera and a wireless transceiver. The wireless transceiver receives wireless packets (e.g., Wi-Fi packets) from one or more mobile devices associated with one or more persons. The channel state information (CSI) is determined based on signals associated with the packets, and first motion characteristics are determined based on the CSI data. Congruently, the camera generates images, and associated image data is received, wherein the image data is associated with the one or more persons. Second motion characteristics are determined based on the image data. The first motion characteristics are matched with the second motion characteristics along with a quantified uncertainty, and the matched motion characteristics are assigned with weights that are based on the second motion characteristics (e.g., image-based). The one or more persons are identified based on the matched motion characteristics and the weights.
