METHOD FOR FINDING ALL FRONTAL FACES IN ARBITRARILY COMPLEX VISUAL SCENES

A method for detecting a face in an image includes the steps of applying the image to a first classification tool that determines a rotational angle for rotating the image that makes the image most resemble an upright face; rotating the image by the rotational angle determined by the first classification tool; and applying the rotated image to a second classification tool, which determines whether the rotated image represents a frontal face or not.
