Anomaly Detection using Pattern-of-Life Visual Metaphors (2019)
Journal Article
Happa, J., Bashford-Rogers, T., Agrafiotis, I., Goldsmith, M., & Creese, S. (in press). Anomaly Detection using Pattern-of-Life Visual Metaphors. IEEE Access, https://doi.org/10.1109/ACCESS.2017.DOI

Complex dependencies exist across the technology estate, users and purposes of machines. This can make it difficult to efficiently detect attacks. Visualization to date is mainly used to communicate patterns of raw logs, or to visualize the output of... Read More about Anomaly Detection using Pattern-of-Life Visual Metaphors.

Learning preferential perceptual exposure for HDR displays (2019)
Journal Article
Bashford-Rogers, T., Melo, M., Debattista, K., Marnerides, D., Bessa, M., & Chalmers, A. (2019). Learning preferential perceptual exposure for HDR displays. IEEE Access, 7, 2169-3536. https://doi.org/10.1109/ACCESS.2019.2898910

High Dynamic Range (HDR) displays are capable of displaying a wider dynamic range of values than conventional displays. As HDR content becomes more ubiquitous, the use of these displays is likely to accelerate. As HDR displays can present a wider ran...

Audio-visual-olfactory resource allocation for tri-modal virtual environments (2019)
Journal Article
Doukakis, E., Debattista, K., Bashford-Rogers, T., Dhokia, A., Asadipour, A., Chalmers, A., & Harvey, C. (2019). Audio-visual-olfactory resource allocation for tri-modal virtual environments. IEEE Transactions on Visualization and Computer Graphics, 25(5), 1865-1875. https://doi.org/10.1109/TVCG.2019.2898823

Virtual Environments (VEs) provide the opportunity to simulate a wide range of applications, from training to entertainment, in a safe and controlled manner. For applications which require realistic representations of real world environments, the VEs... Read More about Audio-visual-olfactory resource allocation for tri-modal virtual environments.

Uniform color space based high dynamic range video compression (2018)
Journal Article

ExpandNet: A deep convolutional neural network for high dynamic range expansion from low dynamic range content (2018)
Journal Article
Marnerides, D., Bashford-Rogers, T., Hatchett, J., & Debattista, K. (2018). ExpandNet: A deep convolutional neural network for high dynamic range expansion from low dynamic range content. Computer Graphics Forum, 37(2), 37-49. https://doi.org/10.1111/cgf.13340

High dynamic range (HDR) imaging provides the capability of handling real world lighting as opposed to the traditional low dynamic range (LDR) which struggles to accurately represent images with higher dynamic range. However, most imaging content is... Read More about ExpandNet: A deep convolutional neural network for high dynamic range expansion from low dynamic range content.
