Abstract
An apparatus for estimating a facial pose. The apparatus includes a pre-processing module that provides feature points of a subject'"'"'s face of a received image, and a pose-estimation module that computes sizes of a left half plane and a right half plane of the face from the provided feature points, and a lateral rotation angle of the face from the computed sizes.

19. A face recognition system comprising:
-
a face-image database that stores face images;
an image-providing module that provides an image including a face image of a subject that is being searched for;
a facial-pose-estimation module that computes a lateral rotation angle of a left half plane and a right half plane of the subject'"'"'s face from a size ratio thereof; and
an image-comparison module that rotates the face image of the subject by the computed rotation angle in the opposite direction, and searches for an image similar to the face image of the subject. - View Dependent Claims (20)
