<p>An image recognition system (10) is provided for identifying predetermined individual members of a viewing audience in a monitored area. A pattern image signature is extracted (98) and is stored (100) corresponding to each predetermined individual member of the viewing audience to be identified. An audience scanner (12) includes audience locating circuitry (30, 18) for locating individual audience members in the monitored area. A video image (28A, 22A) is captured (12, 18, 22) for each of the located individual audience members in the monitored area. A pattern image signature is extracted (110) from the captured image. The extracted pattern image signature is compared (112, 114) with each of the stored pattern image signatures (100) to identify a particular one of the predetermined audience members. These steps are repeated to identify all of the located individual audience members in the monitored area.</p> |
