An image recognition method and system are provided for identifying predetermined individual members of a viewing audience in a monitored area. A pattern image signature is stored corresponding to each predetermined individual member of the viewing audience to be identified. An audience scanner includes audience locating circuitry for locating individual audience members in the monitored area. A video image is captured for each of the located individual audience members in the monitored area. A pattern image signature is extracted from the captured image.
