Modelling spatio-temporal saliency to predict gaze direction for short videos

S Marat, T Ho Phuoc, L Granjon, N Guyader… - International journal of …, 2009 - Springer
This paper presents a spatio-temporal saliency model that predicts eye movement during
video free viewing. This model is inspired by the biology of the first steps of the human visual …

[HTML][HTML] Do low spatial frequencies explain the extremely fast saccades towards human faces?

N Guyader, A Chauvin, M Boucart, C Peyrin - Vision research, 2017 - Elsevier
The visual perception of human faces by man is fast and efficient compared to that of other
categories of objects. Using a saccadic choice task, recent studies showed that participants …

[HTML][HTML] Image phase or amplitude? Rapid scene categorization is an amplitude-based process

N Guyader, A Chauvin, C Peyrin, J Hérault… - Comptes Rendus …, 2004 - Elsevier
Models of the visual cortex are based on image decomposition according to the Fourier
spectrum (amplitude and phase). On one hand, it is commonly believed that phase information is …

[HTML][HTML] How saliency, faces, and sound influence gaze in dynamic social scenes

A Coutrot, N Guyader - Journal of vision, 2014 - iovs.arvojournals.org
Abstract Abstract: Abstract Conversation scenes are a typical example in which classical
models of visual attention dramatically fail to predict eye positions. Indeed, these models rarely …

Influence of soundtrack on eye movements during video exploration

A Coutrot, N Guyader, G Ionescu… - Journal of Eye Movement …, 2012 - hal.science
Models of visual attention rely on visual features such as orientation, intensity or motion to
predict which regions of complex scenes attract the gaze of observers. So far, sound has …

Improving visual saliency by adding 'face feature map'and 'center bias'

S Marat, A Rahman, D Pellerin, N Guyader… - Cognitive …, 2013 - Springer
Faces play an important role in guiding visual attention, and thus, the inclusion of face
detection into a classical visual attention model can improve eye movement predictions. In this …

Spatial frequency processing in scene-selective cortical regions

L Kauffmann, S Ramanoël, N Guyader, A Chauvin… - NeuroImage, 2015 - Elsevier
Visual analysis begins with the parallel extraction of different attributes at different spatial
frequencies. Low spatial frequencies (LSF) convey coarse information and are characterized …

An eye fixation–related potentials analysis of the P300 potential for fixations onto a target object when exploring natural scenes

H Devillez, N Guyader, A Guérin-Dugué - Journal of vision, 2015 - jov.arvojournals.org
The P300 event-related potential has been extensively studied in electroencephalography
with classical paradigms that force observers to not move their eyes. This potential is …

Coarse-to-fine categorization of visual scenes in scene-selective cortex

…, S Ramanoël, C Giavarini, N Guyader… - Journal of cognitive …, 2014 - direct.mit.edu
Neurophysiological, behavioral, and computational data indicate that visual analysis may start
with the parallel extraction of different elementary attributes at different spatial frequencies …

Twice-daily neuronavigated intermittent theta burst stimulation for bipolar depression: a randomized sham-controlled pilot study

…, M Peré, S Harquel, A Chauvin, N Guyader… - Neurophysiologie …, 2019 - Elsevier
The safety and efficacy of neuronavigated intermittent theta burst stimulation (iTBS) in patients
with bipolar depression has not yet been investigated. We hypothesized the superiority of …
