Deep synthesis of cloud lighting (2022)
Journal Article

Current appearance models for the sky are able to represent clear sky illumination to a high degree of accuracy. However, these models all lack a common feature of real-skies: clouds. These are an essential component for many applications which rely... Read More about Deep synthesis of cloud lighting.

Ensemble metropolis light transport (2021)
Journal Article

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.

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...

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.

Assessing a decision support tool for SOC analysts (2020)
Journal Article

It is difficult to discern real-world consequences of attacks on an enterprise when investigating network-centric data alone. In recent years, many tools have been developed to help understand attacks using visualization, but few aim to predict real-... Read More about Assessing a decision support tool for SOC analysts.

Per-pixel classification of clouds from whole sky HDR images (2020)
