1. A method for determining the presence of a face from image data, said method comprising the steps of:

  • (a) prescreening the image data with a first algorithm, the first algorithm determining a plurality of face candidates utilizing a pattern matching technique that identifies image windows likely to contain faces based on color and shape information; and

    (b) operating on the face candidates with a second algorithm, the second algorithm processing the face candidates using a posterior probability function classifier to determine the presence of the face.
