A survey of optimal transport for computer graphics and computer vision

N Bonneel, J Digne - Computer Graphics Forum, 2023 - Wiley Online Library
Optimal transport is a long‐standing theory that has been studied in depth from both
theoretical and numerical point of views. Starting from the 50s this theory has also found a …

Analysis and synthesis of digital dyadic sequences

AGM Ahmed, M Skopenkov, M Hadwiger… - ACM Transactions on …, 2023 - dl.acm.org
We explore the space of matrix-generated (0, m, 2)-nets and (0, 2)-sequences in base 2,
also known as digital dyadic nets and sequences. In computer graphics, they are arguably …

Blue noise for diffusion models

X Huang, C Salaun, C Vasconcelos… - ACM SIGGRAPH 2024 …, 2024 - dl.acm.org
Most of the existing diffusion models use Gaussian noise for training and sampling across all
time steps, which may not optimally account for the frequency contents reconstructed by the …

FAST: Filter-Adapted Spatio-Temporal Sampling for Real-Time Rendering

W Donnelly, A Wolfe, J Bütepage, J Valdés - Proceedings of the ACM on …, 2024 - dl.acm.org
Stochastic sampling techniques are ubiquitous in real-time rendering, where performance
constraints force the use of low sample counts, leading to noisy intermediate results. To …

Curl Noise Jittering

JA Bærentzen, JR Frisvad, J Martínez - SIGGRAPH Asia 2023 …, 2023 - dl.acm.org
We propose a method for implicitly generating blue noise point sets. Our method is based on
the observations that curl noise vector fields are volume-preserving and that jittering can be …

Example-Based Sampling with Diffusion Models

B Doignies, N Bonneel, D Coeurjolly, J Digne… - SIGGRAPH Asia 2023 …, 2023 - dl.acm.org
Much effort has been put into developing samplers with specific properties, such as
producing blue noise, low-discrepancy, lattice or Poisson disk samples. These samplers can …

Quad-Optimized Low-Discrepancy Sequences

V Ostromoukhov, N Bonneel, D Coeurjolly… - ACM SIGGRAPH 2024 …, 2024 - dl.acm.org
The convergence of Monte Carlo integration is given by the uniformity of samples as well as
the regularity of the integrand. Despite much effort dedicated to producing excellent …

Image Printing on Stones, Wood, and More

AGM Ahmed - ACM SIGGRAPH 2023 Posters, 2023 - dl.acm.org
Image engraving on caves is one of the oldest forms of expression and communication
known to human beings, preceding structured written languages, and arguably even spoken …

The Fall of Al-Andalus and the Evolution of its Memory in Modern Arab-Muslim Historiography

M Kabha - The Maghreb Review, 2023 - muse.jhu.edu
This article explores the Fall of al-Andalus and its use in the development of its memory in
modern Arab-Muslim historiography. After its final demise in 1492, Andalusia gradually …
