Differentiable Physically Based Rendering: Algorithms, Systems and Applications
Physically based rendering methods can create photorealistic images by simulating the propagation and interaction of light in a virtual scene. Given a scene description including the shape of objects, participating media, material properties, etc., the sim ...
EPFL2022Perceptual Quality of Point Clouds with application to Compression
Modern information technologies and human-centric communication systems employ advanced content representations for richer portrayals of the real world. The newly adopted imaging modalities offer additional information cues and permit the depiction of real ...
EPFL2021Visual Attention and Perceptual Quality in Omnidirectional Imaging
Omnidirectional imaging has reached a level of widespread availability driven by recent advances in integrated circuit technology, image sensors, and computer graphics which allow now capturing, rendering and displaying of such type of immersive content in ...
EPFL2020PointXR: A toolbox for visualization and subjective evaluation of point clouds in virtual reality
Touradj Ebrahimi, Evangelos Alexiou, Nanyang Yang
In this study, we explore the use of virtual reality to subjectively evaluate the visual quality of point cloud contents. To this aim, we develop the PointXR toolbox, a set of Unity applications that can host experiments under variants of interactive and p ...
2020An in-depth analysis of single-image subjective quality assessment of light field contents
Quality assessment of light field images poses new questions and challenges, due to the enriched nature of the content and the possibilities it offers at the rendering step. Image-based rendering is conventionally used to showcase the increased capabilitie ...

IEEE2019Body-machine interfaces for non-homologous human-machine interactions
Virtual reality (VR), the interactive experience of being immersed in a simulated environment, has seen a tremendous development in the last years. Numerous applications came into being, ranging from flight simulators through a virtual ascent of Mount Ever ...
EPFL2019On the Influence of the Supine Posture on Simulation Sickness in Virtual Reality
Virtual Reality (VR) has the capability of fully immersing users into a wide variety of gaming experiences where the sole focus of the user is on that experience itself. One problem that often occurs when it comes to VR experiences is that of simulation si ...
2019Adequacy of Immersive Virtual Reality for the Perception of Daylit Spaces: Comparison of Real and Virtual Environments
Marilyne Andersen, Jan Wienold, Kynthia Chamilothori
This article presents a novel experimental method that uses a virtual reality (VR) headset, aiming to provide an alternative environment for the conduction of subjective assessments of daylit spaces. This method can overcome the difficulty of controlling t ...
