Recognition of unfamiliar faces is susceptible to image differences caused by angular sizes subtended from the face to the camera. Research on perception of cubes suggests that apparent distortions of a shape due to large camera angle are correctable...

Because stereoscopic depth cues are not present in an ordinary photograph, matching a two-dimensional (2-D) photograph to a three-dimensional (3-D) face requires establishing a correspondence between information derived from monocular depth cues and...
