A living mesoscopic cellular automaton made of skin scales
L Manukyan, SA Montandon, A Fofonjka, S Smirnov… - Nature, 2017 - nature.com
In vertebrates, skin colour patterns emerge from nonlinear dynamical microscopic systems of
cell interactions. Here we show that in ocellated lizards a quasi-hexagonal lattice of skin …

A survey of digital stippling
In this article we survey techniques for the digital simulation of hand-made stippling—one of
the core techniques developed within non-photorealistic/expressive rendering. Over the …

Blue noise sampling with controlled aliasing
D Heck, T Schlömer, O Deussen - ACM Transactions on Graphics (TOG), 2013 - dl.acm.org
In this article we revisit the problem of blue noise sampling with a strong focus on the
spectral properties of the sampling patterns. Starting from the observation that oscillations in …

Low-discrepancy blue noise sampling
AGM Ahmed, H Perrier, D Coeurjolly… - ACM Transactions on …, 2016 - dl.acm.org
We present a novel technique that produces two-dimensional low-discrepancy (LD) blue
noise point sets for sampling. Using one-dimensional binary van der Corput sequences, we …

Active mini-batch sampling using repulsive point processes
The convergence speed of stochastic gradient descent (SGD) can be improved by actively
selecting mini-batches. We explore sampling schemes where similar data points are less …

Variance analysis for Monte Carlo integration
A Pilleboue, G Singh, D Coeurjolly… - ACM Transactions on …, 2015 - dl.acm.org
We propose a new spectral analysis of the variance in Monte Carlo integration, expressed in
terms of the power spectra of the sampling pattern and the integrand involved. We build our …

Gaussian blue noise
Among the various approaches for producing point distributions with blue noise spectrum,
we argue for an optimization framework using Gaussian kernels. We show that with a wise …

Semi‐Procedural Textures Using Point Process Texture Basis Functions
P Guehl, R Allegre, JM Dischler… - Computer Graphics …, 2020 - Wiley Online Library
We introduce a novel semi‐procedural approach that avoids drawbacks of procedural
textures and leverages advantages of data‐driven texture synthesis. We split synthesis in …
