Journal Article
Bitterli, B., Rousselle, F., Moon, B., Iglesias-Guitián, J. A., Adler, D., Mitchell, K., Jarosz, W., & Novák, J. (2016). Nonlinearly Weighted First-order Regression for Denoising Monte Carlo Renderings. Computer Graphics Forum, 35(4), 107-117. https://doi.org/10.1111/cgf.12954

We address the problem of denoising Monte Carlo renderings by studying existing approaches and proposing a new algorithm that yields state-of-the-art performance on a wide range of scenes. We analyze existing approaches from a theoretical and empiric... Read More about Nonlinearly Weighted First-order Regression for Denoising Monte Carlo Renderings.

Guided ecological simulation for artistic editing of plant distributions in natural scenes (2015)
Journal Article
Bradbury, G. A., Subr, K., Koniaris, C., Mitchell, K., & Weyrich, T. (2015). Guided ecological simulation for artistic editing of plant distributions in natural scenes. The Journal of Computer Graphics Techniques, 4(4), 28-53

In this paper we present a novel approach to author vegetation cover of large natural scenes. Unlike stochastic scatter-instancing tools for plant placement (such as multi-class blue noise generators), we use a simulation based on ecological processe...

Adaptive rendering with linear predictions (2015)
Journal Article
Moon, B., Iglesias-Guitian, J. A., Yoon, S.-E., & Mitchell, K. (2015). Adaptive rendering with linear predictions. ACM transactions on graphics, 34(4), 121:1-121:11. https://doi.org/10.1145/2766992

We propose a new adaptive rendering algorithm that enhances the
performance of Monte Carlo ray tracing by reducing the noise, i.e.,
variance, while preserving a variety of high-frequency edges in rendered
images through a novel prediction based re... Read More about Adaptive rendering with linear predictions.

Error analysis of estimators that use combinations of stochastic sampling strategies for direct illumination (2014)
Journal Article
Subr, K., Nowrouzezahrai, D., Jarosz, W., Kautz, J., & Mitchell, K. (2014). Error analysis of estimators that use combinations of stochastic sampling strategies for direct illumination. Computer Graphics Forum, 33(4), 93-102. https://doi.org/10.1111/cgf.12416

We present a theoretical analysis of error of combinations of Monte Carlo estimators used in image synthesis. Importance sampling and multiple importance sampling are popular variance-reduction strategies. Unfortunately, neither strategy improves the...

Survey of texture mapping techniques for representing and rendering volumetric mesostructure (2014)
Journal Article
Koniaris, B., Cosker, D., Yang, X., & Mitchell, K. (2014). Survey of texture mapping techniques for representing and rendering volumetric mesostructure. The Journal of Computer Graphics Techniques, 3(2), 18-60

Representation and rendering of volumetric mesostructure using texture mapping can potentially allow the display of highly detailed, animated surfaces at a low performance cost. Given the need for consistently more detailed and dynamic worlds rendere... Read More about Survey of texture mapping techniques for representing and rendering volumetric mesostructure.

Iterative image warping (2012)
Journal Article

Animated image sequences often exhibit a large amount of inter-frame coherence which standard rendering algorithms and pipelines are ill-equipped to exploit, limiting their efficiency. To address this inefficiency we transfer rendering results across... Read More about Iterative image warping.
