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 ...

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
