Using raytraverse to render high accuracy images
Raytraverse is a python based software that helps to efficiently organize and guide the sampling of a lighting simulation within a scene. Radiance is embedded within Raytraverse to provide accurate and efficient solutions for each sampled ray. This talk wi ...
2023Metamaterial graphene photodetector with bandwidth exceeding 500 gigahertz
Although graphene has met many of its initially predicted optoelectronic, thermal, and mechanical properties, photodetectors with large spectral bandwidths and extremely high frequency responses remain outstanding. In this work, we demonstrate a >500 gigah ...
AMER ASSOC ADVANCEMENT SCIENCE2023DyNCA: 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 ...
