Dynamic clustering and propagation of congestion in heterogeneously congested urban traffic networks

Nikolaos Geroliminis, Mohammadreza Saeedmanesh

The problem of clustering in urban traffic networks has been mainly studied in static framework by considering traffic conditions at a given time. Nevertheless, it is important to underline that traffic is a strongly time-variant process and it needs to be ...

Multisensory perception research has largely focused on exteroceptive signals, but recent evidence has revealed the integration of exteroceptive signals with interoceptive information. Such research revealed that heartbeat signals affect sensory (e.g., vis ...

Daylight Management in Mediterranean Cities: When Shortage Is Not the Issue

Gloria Serra Coch

Natural resources such as daylight and sunlight are highly appreciated in countries with prevailing overcast skies. Taking advantage of this scarce resource contributes to saving energy on artificial lighting. In contrast to northern, southern European cit ...

Pose and Pathosformel in Aby Warburg’s Bilderatlas

Sabine Süsstrunk, Leonardo Laurence Impett

look at Aby Warburg’s concept of Pathosformel, the repeatable formula for the expression of emotion, through the depiction of human pose in art. Using crowdsourcing, we annotate 2D human pose in one-third of the panels of Warburg’s atlas of art, and perfor ...

Contextual Interpretation and Contextual Modulation across the entire visual field

Michael Herzog

Perception of an element can be strongly modulated by surround. Likewise, neural firing of a neuron can strongly be influenced by stimuli outside the classical receptive field. Contextual modulation is often seen as a limitation of the visual system, where ...

Saliency Detection Using Regression Trees on Hierarchical Image Segments

Sabine Süsstrunk, Appu Shaji, Gökhan Yildirim

The currently best performing state-of-the-art saliency detection algorithms incorporate heuristic functions to evaluate saliency. They require parameter tuning, and the relationship between the parameter value and visual saliency is often not well underst ...

Multi-pose lipreading and audio-visual speech recognition

Jean-Philippe Thiran, Virginia Estellers Casas

In this article, we study the adaptation of visual and audio-visual speech recognition systems to non-ideal visual conditions. We focus on overcoming the effects of a changing pose of the speaker, a problem encountered in natural situations where the speak ...

Finding Audio-Visual Events in Informal Social Gatherings

In this paper we address the problem of detecting and localizing objects that can be both seen and heard, e.g., people. This may be solved within the framework of data clustering. We propose a new multimodal clustering algorithm based on a Gaussian mixture ...

Wearable systems for audio, visual and gaze monitoring

Aude Billard, Basilio Noris, Jean-Baptiste Keller

A non-obtrusive portable device, wearable from infancy through adulthood, mounted with i) a set of two or more optical device(s) providing visual and audio information as perceived by the user ii) an actuated mirror or optical device returning visual infor ...

Dynamics of Visual Feature Integration and Decision Making

Johannes Rüter

The human brain analyzes a visual object first by basic feature detectors. These features are integrated in subsequent stages of the visual hierarchy. Generally it is assumed that the information about these basic features is lost once the information is s ...
