Rate Distortion Optimized Graph Partitioning for Omnidirectional Image Coding

Pascal Frossard, Francesca De Simone, Thomas Maugey, Mira Rizkallah

Omnidirectional images are spherical signals captured by cameras with 360-degree field of view. In order to be compressed using existing encoders, these signals are mapped to planar domain. A commonly used planar representation is the equirectangular one, ...

The effects of visual realism, spatial abilities, and competition on performance in map-based route learning in men

Rebecca Francelet

We report on how visual realism might influence map-based route learning performance in a controlled laboratory experiment with 104 male participants in a competitive context. Using animations of a dot moving through routes of interest, we find that partic ...

The subtle mechanics of an avalanche – as seen in 3D

Drawing on the fact that the snow in an avalanche can behave like both a solid and a fluid, a young researcher at EPFL and WSL Institute for Snow and Avalanche Research SLF has managed to simulate a snow slab avalanche with unrivaled precision. ...

Improved calibration of vertical scanning optical profilometers for spherical profiles measurements

Toralf Scharf, Wilfried Noell, Jeremy Béguelin

A new method for calibrating optical scanning profilometers is presented. Especially adapted to spherical and aspherical profile measurements, it shows an increase of accuracy bigger than one order of magnitude for radius of curvature measurements. Calibra ...

Learning Intelligent Dialogs for Bounding Box Annotation

Ksenia Konyushkova, Vittorio Ferrari

We introduce Intelligent Annotation Dialogs for bounding box annotation. We train an agent to automatically choose a sequence of actions for a human annotator to produce a bounding box in a minimal amount of time. Specifically, we consider two actions: box ...

Using Networks to Visualize Publications

Dario Rodighiero

Retrieval systems are often shaped as lists organized in pages. However, the majority of users look at the first page ignoring the other ones. This presentation concerns an alterna- tive way to present the results of a query using network visualizations.  ...

The Hermenutic Circle of Data Visualization

Dario Rodighiero

According to Don Ihde (1990, 80–97), hermeneutic relations are a specific kind of technologically mediated I-world relations in which the technology must be “read” and “interpreted” in order to access the world. More recently, Peter-Paul Verbeek (2010, 145 ...
