Visual Distortions in 360-degree Videos

Pascal Frossard, Francesca De Simone, Roberto Gerson De Albuquerque Azevedo

Omnidirectional (or 360-degree) images and videos are emergent signals in many areas such as robotics and virtual/augmented reality. In particular, for virtual reality, they allow an immersive experience in which the user is provided with a 360-degree fiel ...

Experimental demonstration of ray-rotation sheets

Toralf Scharf

We have built microstructured sheets that rotate, on transmission, the direction of light rays by an arbitrary, but fixed, angle around the sheet normal. These ray-rotation sheets comprise two pairs of confocal lenticular arrays. In addition to rotating th ...

Physical and 3D Numerical Simulations of the Flow in the Tailrace of a Hydroelectric Power Plant to Design Fishway Entries

Giovanni De Cesare, Pierre Bourqui

This work is part of a project aiming at dimensioning a fishway for a hydroelectric power plant on the Rhine River. Here we only focus on the design of the fishway entrances, for which a physical model of the draft tubes and tailrace of the powerplant was ...

Impact of Visualisation Strategy for Subjective Quality Assessment of Point Clouds

Touradj Ebrahimi, Evangelos Alexiou

Point clouds have recently emerged as a promising and practical solution to code 3D visual information for immersive applications. Among other challenges, objective and subjective quality assessments are still open problems for this type of visual data rep ...

Learning to Segment 3D Linear Structures Using Only 2D Annotations

Pascal Fua, Mathieu Salzmann, Agata Justyna Mosinska, Mateusz Kozinski

We propose a loss function for training a Deep Neural Network (DNN) to segment volumetric data, that accommodates ground truth annotations of 2D projections of the training volumes, instead of annotations of the 3D volumes themselves. In consequence, we si ...

Towards subjective quality assessment of point cloud imaging in augmented reality

Touradj Ebrahimi, Evgeniy Upenik, Evangelos Alexiou

Recently, there has been an increased interest in capture, processing and rendering of visual content in form of point clouds. Among other challenges, subjective and objective quality evaluation of point clouds are still open problems. Most proposed subjec ...

Comparison and evaluation of light field image coding approaches

Touradj Ebrahimi, Martin Rerabek, Irene Viola

The recent advances in light field imaging, supported among others by the introduction of commercially available cameras e.g. Lytro or Raytrix, are changing the ways in which visual content is captured and processed. Efficient storage and delivery systems ...

1024-Channel Single 5W FPGA Towards High-quality Portable 3D Ultrasound Platform

Jean-Philippe Thiran, Giovanni De Micheli, Marcel Arditi, Aya Mohamed Naguib Ahmed Ibrahim, Ahmet Caner Yüzügüler

Volumetric Ultrasound (US) imaging is an emerging tech- nology for medical US applications. Typically, US imaging is 2D, where a number of vibrating elements, arranged in an array, are used to scan 2D cross-sections of the human body. In volumetric US a ma ...

Robust and Accurate 3D Head Pose Estimation through 3DMM and Online Head Model Reconstruction

Jean-Marc Odobez, Kenneth Alberto Funes Mora, Yu Yu

Accurate and robust 3D head pose estimation is important for face related analysis. Though high accuracy has been achieved by previous works based on 3D morphable model (3DMM), their performance drops with extreme head poses because such models usually onl ...
