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...

The development and evaluation of a virtual radiotherapy treatment machine using an immersive visualisation environment (2005)
Journal Article
Bridge, P., Appleyard, R. M., Ward, J. W., Philips, R., & Beavis, A. W. (2007). The development and evaluation of a virtual radiotherapy treatment machine using an immersive visualisation environment. Computers & education, 49(2), 481-494. https://doi.org/10.1016/j.compedu.2005.10.006

Due to the lengthy learning process associated with complicated clinical techniques, undergraduate radiotherapy students can struggle to access sufficient time or patients to gain the level of expertise they require. By developing a hybrid virtual en... Read More about The development and evaluation of a virtual radiotherapy treatment machine using an immersive visualisation environment.

The use of 3D information in face recognition (2005)
Journal Article
Liu, C. H., & Ward, J. (2006). The use of 3D information in face recognition. Vision Research, 46(6-7), 768-773. https://doi.org/10.1016/j.visres.2005.10.008

Effects of shading in face recognition have often alluded to 3D shape processing. However, research to date has failed to demonstrate any use of important 3D information. Stereopsis adds no advantage in face encoding [Liu, C. H., Ward, J., & Young,... Read More about The use of 3D information in face recognition.

VRVision: A new tool for the display of 3-D images in behavioral research (2005)
Journal Article
Ward, J., & Liu, C. H. (2005). VRVision: A new tool for the display of 3-D images in behavioral research. Behavior research methods, 37(3), 464-469. https://doi.org/10.3758/BF03192715

Researchers using three-dimensional (3-D) scenes in their studies often spend a lot of time prerendering the scenes into a set of images for later presentations. To improve efficiency, we have developed a new plug-in program for MATLAB that eliminate... Read More about VRVision: A new tool for the display of 3-D images in behavioral research.

Constructive implicit fitting (2005)
Journal Article
Li, Q., Griffiths, J. G., & Ward, J. (2006). Constructive implicit fitting. Computer aided geometric design, 23(1), 17-44. https://doi.org/10.1016/j.cagd.2005.04.011

In this paper, we present a constructive method for fitting both an explicit and an implicit curve or surface to a set of scattered points by using gate functions. With this technique, the data are first partitioned with geometric primitives into sma... Read More about Constructive implicit fitting.

Immersive visualization training of radiotherapy treatment (2005)
Journal Article
Phillips, R., Ward, J. W., & Beavis, A. W. (2005). Immersive visualization training of radiotherapy treatment. Studies in health technology and informatics, 111, 390 - 396

External radiation beam treatment of cancer tumours involves delivery of invisible radiation beams through the body where internal structures can not be seen. Beam targeting of patient anatomy has to very accurate to achieve the desired therapeutic r... Read More about Immersive visualization training of radiotherapy treatment.

Face matching across 2-D and 3-D representations (2004)
Journal Article
Young, A., Liu, C., & Ward, J. (2004). Face matching across 2-D and 3-D representations. Perception, 33(ECVP Abstract Supplement), 109 - 109

Research on face recognition has mainly relied on photographic or video stimuli where the 3-D volumetric information of a face for both training and test materials is limited to the depth cues given by the 2-D pictorial representation. In reality, ho... Read More about Face matching across 2-D and 3-D representations.

Implicit fitting using radial basis functions with ellipsoid constraint (2004)
Journal Article
Li, Q., Wills, D., Phillips, R., Viant, W. J., Griffiths, J. G., & Ward, J. (2004). Implicit fitting using radial basis functions with ellipsoid constraint. Computer graphics forum : journal of the European Association for Computer Graphics, 23(1), 55-69. https://doi.org/10.1111/j.1467-8659.2004.00005.x

Implicit planar curve and surface fitting to a set of scattered points plays an important role in solving a wide variety of problems occurring in computer graphics modelling, computer graphics animation, and computer assisted surgery. The fitted impl... Read More about Implicit fitting using radial basis functions with ellipsoid constraint.
