GPU-accelerated depth codec for real-time, high-quality light field reconstruction

Journal Article
Koniaris, B., Kosek, M., Sinclair, D., & Mitchell, K. (2018)
GPU-accelerated depth codec for real-time, high-quality light field reconstruction. Proceedings of the ACM on Computer Graphics and Interactive Techniques, 1(1), 1-15. https://doi.org/10.1145/3203193
Pre-calculated depth information is essential for efficient light field video rendering, due to the prohibitive cost of depth estimation from color when real-time performance ...

Journal Article
Powers, S. T., Ekárt, A., & Lewis, P. R. (2018)
Modelling enduring institutions: The complementarity of evolutionary and agent-based approaches. Cognitive Systems Research, 52, 67-81. https://doi.org/10.1016/j.cogsys.2018.04.012
Empirical work has shown that societies can sometimes avoid antisocial outcomes , such as the Tragedy of the Commons, by establishing institutional rules that govern their int...

From Faces to Outdoor Light Probes

Journal Article
Calian, D. A., Lalonde, J., Gotardo, P., Simon, T., Matthews, I., & Mitchell, K. (2018)
From Faces to Outdoor Light Probes. Computer Graphics Forum, 37(2), 51-61. doi:10.1111/cgf.13341
Image‐based lighting has allowed the creation of photo‐realistic computer‐generated content. However, it requires the accurate capture of the illumination conditions, a task n...

Empowerment and embodiment for collaborative mixed reality systems: Empowerment and Embodiment

Journal Article
Pan, Y., Sinclair, D., & Mitchell, K. (2018)
Empowerment and embodiment for collaborative mixed reality systems: Empowerment and Embodiment. Computer Animation and Virtual Worlds, 29(3-4), https://doi.org/10.1002/cav.1838
We present several mixed‐reality‐based remote collaboration settings by using consumer head‐mounted displays. We investigated how two people are able to work together in these...

Compressed Animated Light Fields with Real-time View-dependent Reconstruction

Journal Article
Koniaris, C., Kosek, M., Sinclair, D., & Mitchell, K. (2019)
Compressed Animated Light Fields with Real-time View-dependent Reconstruction. IEEE Transactions on Visualization and Computer Graphics, 25(4), 1666-1680. https://doi.org/10.1109/tvcg.2018.2818156
We propose an end-to-end solution for presenting movie quality animated graphics to the user while still allowing the sense of presence afforded by free viewpoint head motion....

The institutional approach for modeling the evolution of human societies

Journal Article

The institutional approach for modeling the evolution of human societies. Artificial Life, 24(1), 10-28. https://doi.org/10.1162/ARTL_a_00251
Artificial Life is concerned with understanding the dynamics of human societies. A defining feature of any society is its institutions. However, defining exactly what an insti...

The co-evolution of social institutions, demography, and large-scale human cooperation

Journal Article
Powers, S. T., & Lehmann, L. (2013)
The co-evolution of social institutions, demography, and large-scale human cooperation. Ecology Letters, 16(11), 1356-1364. https://doi.org/10.1111/ele.12178
Human cooperation is typically coordinated by institutions, which determine the outcome structure of the social interactions individuals engage in. Explaining the Neolithic tr...

Punishment can promote defection in group-structured populations

Journal Article
Powers, S. T., Taylor, D. J., & Bryson, J. J. (2012)
Punishment can promote defection in group-structured populations. Journal of Theoretical Biology, 311, 107-116. https://doi.org/10.1016/j.jtbi.2012.07.010
Pro-social punishment, whereby cooperators punish defectors, is often suggested as a mechanism that maintains cooperation in large human groups. Importantly, models that suppo...

The concurrent evolution of cooperation and the population structures that support it

Journal Article
Powers, S. T., Penn, A. S., & Watson, R. A. (2011)
The concurrent evolution of cooperation and the population structures that support it. Evolution, 65(6), 1527-1543. https://doi.org/10.1111/j.1558-5646.2011.01250.x
The evolution of cooperation often depends upon population structure, yet nearly all models of cooperation implicitly assume that this structure remains static. This is a simp...
