Ensemble metropolis light transport (2021)
Journal Article
Bashford-Rogers, T., Paulo Santos, L., Marnerides, D., & Debattista, K. (2022). Ensemble metropolis light transport. ACM Transactions on Graphics, 41(1), Article 5. https://doi.org/10.1145/3472294

This article proposes a Markov Chain Monte Carlo (MCMC) rendering algorithm based on a family of guided transition kernels. The kernels exploit properties of ensembles of light transport paths, which are distributed according to the lighting in the s... Read More about Ensemble metropolis light transport.

Deception in network defences using unpredictability (2021)
Journal Article
Happa, J., Bashford-Rogers, T., Van Rensburg, A. J., Goldsmith, M., & Creese, S. (2021). Deception in network defences using unpredictability. Digital Threats: Research and Practice, 2(4), Article 29. https://doi.org/10.1145/3450973

In this article, we propose a novel method that aims to improve upon existing moving-target defences by making them unpredictably reactive using probabilistic decision-making. We postulate that unpredictability can improve network defences in two key... Read More about Deception in network defences using unpredictability.

The digital resurrection of Margaret Thatcher: Creative, technological and legal dilemmas in the use of deepfakes in screen drama (2021)
Journal Article
Lees, D., Bashford-Rogers, T., & Keppel-Palmer, M. (2021). The digital resurrection of Margaret Thatcher: Creative, technological and legal dilemmas in the use of deepfakes in screen drama. Convergence, 27(4), 954–973. https://doi.org/10.1177/13548565211030452

This article develops from the findings of an interdisciplinary research project that has linked film practice research with computer science and law, in an exercise that seeks to digitally resurrect Margaret Thatcher to play herself in a contemporar...

A fitted radiance and attenuation model for realistic atmospheres (2021)
Journal Article
Wilkie, A., Vévoda, P., Bashford-Rogers, T., Hošek, L., Iser, T., Kolářová, M., …Křivánek, J. (2021). A fitted radiance and attenuation model for realistic atmospheres. ACM Transactions on Graphics, 40(4), https://doi.org/10.1145/3450626.3459758

We present a fitted model of sky dome radiance and attenuation for realistic terrestrial atmospheres. Using scatterer distribution data from atmospheric measurement data, our model considerably improves on the visual realism of existing analytical cl...

Deep HDR hallucination for inverse tone mapping (2021)
Journal Article
Marnerides, D., Bashford-Rogers, T., & Debattista, K. (2021). Deep HDR hallucination for inverse tone mapping. Sensors, 21(12), Article 4032. https://doi.org/10.3390/s21124032

Inverse Tone Mapping (ITM) methods attempt to reconstruct High Dynamic Range (HDR) information from Low Dynamic Range (LDR) image content. The dynamic range of well-exposed areas must be expanded and any missing information due to over/under-exposure... Read More about Deep HDR hallucination for inverse tone mapping.
