Transfer between two- and three-dimensional representations of faces (2006)
Journal Article
Liu, C. H., Ward, J., & Young, A. W. (2006). Transfer between two- and three-dimensional representations of faces. Visual Cognition, 13(1), 51-64. https://doi.org/10.1080/13506280500143391

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...

Face recognition in pictures is affected by perspective transformation but not by the centre of projection (2006)
Journal Article
Liu, C. H., & Ward, J. (2006). Face recognition in pictures is affected by perspective transformation but not by the centre of projection. Perception, 35(12), 1637-1650. https://doi.org/10.1068/p5545

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...

For a subset ψ of PG(N, 2) a known result states that ψ has polynomial degree ≤ r, r ≤ N, if and only if ψ intersects every r-flat of PG(N, 2) in an odd number of points. Certain refinements of this result are considered, and are then applied in the... Read More about The polynomial degree of the Grassmannian G1,n,2.

The insertion of distal locking screws is a difficult task in intra-medullary (IM) nailing operations of long bones and contributes a significant proportion to the overall operating time. The current technique to insert these screws uses numerous flu...

Advantages of 3D methods for face recognition research in humans (2005)
Journal Article
Liu, C., & Ward, J. (2005). Advantages of 3D methods for face recognition research in humans. Lecture notes in computer science, 3723, 244 - 254

Research on face recognition in humans has mainly relied on 2D images. This approach has certain limitations. First, observers become relatively passive in face encoding, although in reality they may be more spontaneous in exploring different views o...
