Steering via the image in local, distributed and collaborative settings (2007)
Presentation / Conference Contribution
Wright, H., & Wood, J. D. Steering via the image in local, distributed and collaborative settings

Computational steering is a valuable mechanism for scientific investigation in which the parameters of a running program can be altered and the results visualized immediately. In a previous paper we put forward an architecture for computational steer... Read More about Steering via the image in local, distributed and collaborative settings.

Smooth piecewise polynomial blending operations for implicit shapes (2007)
Journal Article

In this paper, we present a new set of blending operations for implicitly defined geometric shapes. The proposed shape operators are piecewise polynomial and blending range controllable, and can be constructed to any required degree of smoothness. Th...

Classical Fault Tree Analysis (FTA) can determine the effects of combinations of failure events on a system but cannot capture the significance of the temporal order of events, which may be critical. In this paper, we propose an extension based on fo... Read More about Synthesis and analysis of temporal fault trees with PANDORA: the time of Priority AND gates.

The role of exploratory action in face encoding (2006)
Presentation / Conference Contribution
Liu, C., & Ward, J. The role of exploratory action in face encoding

Research on face recognition has mainly relied on methods where observers are relatively passive viewers of face stimuli. We investigated whether active exploration of 3-D face stimuli could facilitate recognition performance. A yoked design was empl... Read More about The role of exploratory action in face encoding.

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...
