Blue noise for diffusion models

no code implementations7 Feb 2024 Xingchang Huang, Corentin Salaün, Cristina Vasconcelos, Christian Theobalt, Cengiz Öztireli, Gurprit Singh

In this paper, we introduce a novel and general class of diffusion models taking correlated noise within and across images into account.

Efficient Gradient Estimation via Adaptive Sampling and Importance Sampling

no code implementations24 Nov 2023 Corentin Salaün, Xingchang Huang, Iliyan Georgiev, Niloy J. Mitra, Gurprit Singh

Nevertheless, existing algorithms have struggled to efficiently integrate importance sampling into machine learning frameworks.

Joint Sampling and Optimisation for Inverse Rendering

no code implementations27 Sep 2023 Martin Balint, Karol Myszkowski, Hans-Peter Seidel, Gurprit Singh

By combining proportional and finite-difference samples, we continuously reduce the variance of our novel gradient meta-estimators throughout the optimisation process.

Neural Relightable Participating Media Rendering

no code implementations NeurIPS 2021 Quan Zheng, Gurprit Singh, Hans-Peter Seidel

We propose to learn neural representations for participating media with a complete simulation of global illumination.

Perceptual error optimization for Monte Carlo rendering

no code implementations4 Dec 2020 Vassillen Chizhov, Iliyan Georgiev, Karol Myszkowski, Gurprit Singh

To find solutions, we present a set of algorithms that provide varying trade-offs between quality and speed, showing substantial improvements over prior state of the art.
