DyNCA: Real-time Dynamic Texture Synthesis Using Neural Cellular Automata
Sabine Süsstrunk, Tong Zhang, Ehsan Pajouheshgar, Yitao Xu
Current Dynamic Texture Synthesis (DyTS) models can synthesize realistic videos. However, they require a slow iterative optimization process to synthesize a single fixed-size short video, and they do not offer any post-training control over the synthesis p ...

Los Alamitos2023Accelerated deep self-supervised ptycho-laminography for three-dimensional nanoscale imaging of integrated circuits
Yi Jiang, Manuel Guizar Sicairos
Three-dimensional inspection of nanostructures such as integrated circuits is important for security and reliability assurance. Two scanning operations are required: ptychographic to recover the complex transmissivity of the specimen, and rotation of the s ...
2023Vertex function compliant with the Ward identity for quasiparticle self-consistent calculations beyond GW
Alfredo Pasquarello, Aleksei Tal, Wei Chen
We extend the quasiparticle self-consistent approach beyond the GW approximation by using a range separated vertex function. The developed approach yields band gaps, dielectric constants, and band positions with an accuracy similar to highest-level electro ...
2021Hessian Splines For Scanning Transmission X-Ray Microscopy
Michaël Unser, Thomas Jean Debarre
Scanning transmission X-ray microscopy (STXM) produces images in which each pixel value is related to the measured attenuation of an X-ray beam. In practice, the location of the illuminated region does not exactly match the desired uniform pixel grid. This ...
IEEE2020Moiré effects produced by superpositions of micro-lens arrays
Moiré effects result from the superimposition of repetitive structures. The beauty of these moirés comes from the fact that macroscopic shapes seem to appear from the superposition of layers containing microscopic patterns. In addition, the moirés are dyna ...
EPFL2020Level-line moirés by superposition of cylindrical microlens gratings
Jürgen Brugger, Roger Hersch, Thomas Walger, Valentin Flauraud, Théophane Besson
Two superposed layers of transparent cylindrical lenslet gratings create classical moiré fringes when illuminated from behind. We rely on this observation to conceive special devices made of superposed lenslet gratings that produce compelling beating shape ...
2020Parallel Optical Spatial Signal Processing Based on 2x2 MIMO Computational Metasurface
Romain Christophe Rémy Fleury, Ali Momeni, Amirhossein Babaee
We introduce a novel concept of Multi-Input Multi-Output (MIMO) metasurface processor with asymmetric Optical Transfer Function (OTF) which can perform spatial first-order derivation on two orthogonal distinct input signals for both TM and TE polarizations ...
IEEE2020New architecture for the analog front-end of Medipix4
Jean-Michel Sallese, Adil Koukab, Viros Sriskaran
The Medipix4 chip is the latest member of the family of Medipix pixel detector readout chips aimed at high rate spectroscopic X-ray imaging. Unlike its predecessors, it will be possible to tile the chip on all 4 sides permitting seamless large area coverag ...
ELSEVIER2020Reparameterizing Discontinuous Integrands for Differentiable Rendering
Wenzel Alban Jakob, Guillaume Rémi Bruno Loubet
Differentiable rendering has recently opened the door to a number of challenging inverse problems involving photorealistic images, such as computational material design and scattering-aware reconstruction of geometry and materials from photographs. Differe ...
