Abstract: The method of face model alignment on unseen face includes inputting a face image; warping the face image into a standard shaped face based on a model seen by AAM (Active Appearance Model); normalizing the warped image by removing a texture change of the warped image; extracting a face texture from the normalized image; calculating error areas by comparing the face texture with the seen model; and aligning edges of the face texture with edges of the seen model while reducing the difference of the error areas.
