Abstract
Methods, apparatus and systems for human recognition based on one or more gait features detected wirelessly are described. In one example, a described system comprises: a transmitter configured to transmit a first wireless signal through a wireless channel of a venue; a receiver configured to receive a second wireless signal through the wireless channel, wherein the second wireless signal comprises a reflection of the first wireless signal by at least one object in the venue; and a processor. The processor is configured for: obtaining a time series of channel information (CI) of the wireless channel based on the second wireless signal, determining a presence of a person moving in the venue based on the time series of CI (TSCI), extracting at least one gait feature of the person from the TSCI, and recognizing an identity of the person based on the at least one gait feature.
