The fiducial points on the face (such as eye corners, eye centers, eyebrows) cannot always be manually marked or automatically detected with pixel precision. This is generally due to the ambiguous nature of the gray or color patterns at these positions. Also, changes in illumination and pose, effect the perception of image rendering of such fiducials.
