Patent ID: 7027619

Claim:
A method for use in detecting a face of a person, the method comprising: providing image data representative of reflected light of a scene in at least a first and second bandwidth within a reflected infrared radiation range; extracting regions of the scene in the image data representative of reflected light of the scene in the first bandwidth within the reflected infrared radiation range which correspond to one or both eyebrows of a person; extracting regions of the scene in the image data representative of reflected light of the scene in the second bandwidth within the reflected infrared radiation range which correspond to one or both eyes of the person; combining the extracted regions of the scene which correspond to one or both eyebrows of the person with the extracted regions of the scene that correspond to one or both eyes of the person resulting in a composite feature image; and searching the composite feature image based on model data representative of an eye region to detect one or both eyes of the person.
