Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for tracking a product item in an automated-checkout store. One of the methods includes receiving, by a computer system, data collected by multiple image sensors, the received data including data associated with a person, identifying, by the computer system based on the received data, multiple features of the person, extracting, by the computer system based on the identified features, data associated with the person from the received data, wherein the extracted data correspond to multiple time periods, and determining, by the computer system, a location of the person in each of the time periods based on the extracted data corresponding to the time period, wherein the determining includes aggregating the extracted data collected by different image sensors based at least in part on a location and a line of sight of each of the image sensors.
