Estimating Fusion Weights of a Multi-Camera Eye Tracking System by Leveraging User Calibration Data

Jean-Philippe Thiran, Nuri Murat Arar

Cross-ratio (CR)-based eye tracking has been attracting much interest due to its simple setup, yet its accuracy is lower than that of the model-based approaches. In order to improve the estimation accuracy, a multi-camera setup can be exploited rather than ...

Retina Color-Opponency Based Pursuit Implemented Through Spiking Neural Networks in the Neurorobotics Platform

Marc-Oliver Gewaltig, Egidio Falotico, Lorenzo Vannucci, Paul Levi, Georg Hinkel, Stefan Ulbrich, Alessandro Ambrosano, Ugo Albanese, Murat Kirtay

The 'red-green' pathway of the retina is classically recognized as one of the retinal mechanisms allowing humans to gather color information from light, by combining information from L-cones and M-cones in an opponent way. The precise retinal circuitry tha ...

Evaluation of Color Mapping Algorithms in Different Color Spaces

Touradj Ebrahimi

The color gamut supported by current commercial displays is only a subset of the full spectrum of colors visible by the human eye. In High-Definition (HD) television technology, the scope of the supported colors covers 35.9% of the full visible gamut. For ...

Human responsive daylighting in offices : a gaze-driven approach for dynamic discomfort glare assessment

Mandana Sarey Khanie

This dissertation proposes a novel gaze-driven approach for dynamic discomfort glare assessments as a first step towards understanding human responsive comfort with respect to daylight. The objective was to observe the natural gaze behaviour in relation to ...

3D Gaze Estimation from Remote RGB-D Sensors

Kenneth Alberto Funes Mora

The development of systems able to retrieve and characterise the state of humans is important for many applications and fields of study. In particular, as a display of attention and interest, gaze is a fundamental cue in understanding people activities, be ...

Attention Driven Foveated Video Quality Assessment

Touradj Ebrahimi

Contrast sensitivity of the human visual system to visual stimuli can be significantly affected by several mechanisms, e. g., vision foveation and attention. Existing studies on foveation based video quality assessment only take into account static foveati ...

A new device for dynamic luminance mapping and glare risk assessment in buildings

Jean-Louis Scartezzini, Laurent Deschamps, Apiparn Borisuit

High dynamic range imaging has been shown to be a reliable tool to assess luminance maps and glare risk probability in buildings. However, there are some limitations of image capturing time, especially when dealing with highly dynamic and contrasted daylig ...

Investigating Gaze of Children with ASD in Naturalistic Settings

Aude Billard, Nouchine Hadjikhani, Basilio Noris

Background: Visual behavior is known to be atypical in Autism Spectrum Disorders (ASD). Monitor-based eye-tracking studies have measured several of these atypicalities in individuals with Autism. While atypical behaviors are known to be accentuated during ...

Dual Eye-Tracking Methods for the Study of Remote Collaborative Problem Solving

Marc-Antoine Nüssli

Applied eye-tracking has been extensively used for the study of psychological processes. More recently, some researchers have used this technique to study the interaction between people by tracking and analyzing eye-movements of two persons synchronously. ...

Machine Vision-Based Analysis of Gaze and Visual Context : an Application to Visual Behavior of Children with Autism Spectrum Disorders

Basilio Noris

Visual behavior, and specifically gaze directed at objects and people, is a fundamental cue for understanding how children with Autism Spectrum Disorder (ASD) experience and respond to social interaction. Indeed atypical behaviors such as averting the gaze ...
