Oscar Pueyo-Ciutad
Hi! I am Oscar Pueyo-Ciutad, a PhD Candidate in Computational Imaging in the
Graphics & Imaging Lab
supervised by
Prof. Diego Gutierrez
and
Prof. Albert Redo-Sanchez
at Universidad de Zaragoza (Spain).
Previously, I studied a Bachelor's Degree in Computer Engineering and a Master of Engineering in Robotics, Graphics and
Computer Vision at the Universidad de Zaragoza.
During my PhD, I have visited Princeton Computational Imaging Lab for three months, supervised by Prof. Felix Heide.
My research interests are related to Computational Imaging:
Transient, non-line-of-sight and polarization imaging, wave optics and holography, computational photography, and forward and inverse physically-based rendering.

Statistical Denoising of Transient Rendering
Oscar Pueyo-Ciutad, Alvaro Lopez, Diego Gutierrez
EUROGRAPHICS 2026
Transient rendering simulates light in motion, although the stochastic nature of Monte Carlo yields noisy results. By relying on statistics over the transient domain, we achieve a near-optimal trade-off between reduced variance and introduced bias.

Artifact-Resilient Real-Time Holography
Victor Chu, Oscar Pueyo-Ciutad, Ethan Tseng, Florian Schiffers, Grace Kuo, Nathan Matsuda, Albert Redo-Sanchez, Douglas Lanman, Oliver Cossairt, Felix Heide
SIGGRAPH Asia 2025 (Journal track)
Holographic near-eye displays are limited in real-world viewing conditions, where eyelashes and eye floaters degrade image quality. We introduce a differentiable metric to train a network and generate artifact-resilient 3D holograms in real time.

mitransient: Transient light transport in Mitsuba 3
Diego Royo, Jorge Garcia-Pueyo, Miguel Crespo, Oscar Pueyo-Ciutad, Guillermo Enguita, Diego Bielsa
mitransient is a library that adds support to Mitsuba 3 for transient simulations, with support for non-line-of-sight (NLOS) scenes, polarization tracking and differentiable transient rendering.

Time-Gated Polarization for Active Non-Line-Of-Sight Imaging
Oscar Pueyo-Ciutad, Julio Marco, Stephane Schertzer, Frank Christnacher, Martin Laurenzis, Diego Gutierrez, Albert Redo-Sanchez
SIGGRAPH Asia 2024
We integrate polarization in non-line-of-sight imaging and reconstruct features that were invisible to previous methods by leveraging the directional information encoded in the polarization of light.
