Claim One:
1. A method comprising steps of: reading, from a storage device, a first image of a scene that was captured with a first amount of illumination; reading, from the storage device, a second image of the scene that was captured with a second amount of illumination that differs from the first amount of illumination; distinguishing a foreground portion of the scene from a background portion of the scene based on a comparison of the first image to the second image; identifying, in the scene, a crown region that contains a crown of a person's head; identifying portions of the crown region that have been misidentified as belonging to the background portion rather than the foreground portion; and recharacterizing the misidentified portions of the crown region as belonging to the foreground portion rather than the background portion; wherein the steps are performed by an automated device.
