Balancing Attended and Global Stimuli in Perceived Video Quality Assessment

Touradj Ebrahimi

The visual attention mechanism plays a key role in the human perception system and it has a significant impact on our assessment of perceived video quality. In spite of receiving less attention from the viewers, unattended stimuli can still contribute to t ...

Dynamic Visual Attention on the Sphere

Pierre-André Farine, Heinz Hügli, Iva Bogdanova Vandergheynst, Alexandre Bur

In this paper we present a computational model of dynamic visual attention on the sphere which combines static (intensity,chromaticity, orientation) and motion features in order to detect salient locations in omnidirectional image sequences while working d ...

Attention and non-retinotopic feature integration

Michael Herzog, Thomas Otto

Features of moving objects are non-retinotopically integrated along their motion trajectories as demonstrated by a variety of recent studies. The mechanisms of non-retinotopic feature integration are largely unknown. Here, we investigated the role of atten ...

Dynamic Attentive System for Omnidirectional Video

Pierre-André Farine, Iva Bogdanova Vandergheynst

In this paper, we propose a dynamic attentive system for detecting the most salient regions of interest in omnidirectional video. The spot selection is based on computer modeling of dynamic visual attention. In order to operate on video sequences, the proc ...

Visual Attention on the Sphere

Heinz Hügli, Iva Bogdanova Vandergheynst, Alexandre Bur

Human visual system makes an extensive use of visual attention in order to select the most relevant information and speed-up the vision process. Inspired by visual attention, several computer models have been developped and many computer vision application ...

Dynamic Visual Attention: Motion Direction versus Motion Magnitude

Heinz Hügli, Alexandre Bur

Defined as an attentive process in the context of visual sequences, dynamic visual attention refers to the selection of the most informative parts of video sequence. This paper investigates the contribution of motion in dynamic visual attention, and specif ...

The spherical approach to omnidirectional visual attention

Heinz Hügli, Iva Bogdanova Vandergheynst, Alexandre Bur

Computational visual attention (VA) has been widely investigated during the last three decades but the conventional algorithms are not suitable for omnidirectional images which often contain a significant amount of radial distortion. Only recently a comput ...

Motion Integration in Visual Attention Models for Predicting Simple Dynamic Scenes

Heinz Hügli, Alexandre Bur

Visual attention models mimic the ability of a visual system, to detect potentially relevant parts of a scene. This process of attentional selection is a prerequisite for higher level tasks such as object recognition. Given the high relevance of temporal a ...

Adaptive visual attention model

Heinz Hügli, Alexandre Bur

Visual attention, defined as the ability of a biological or artificial vision system to rapidly detect potentially relevant parts of a visual scene, provides a general purpose solution for low level feature detection in a vision architecture. Well consider ...

Optimal Cue Combination for Saliency Computation: A Comparison with Human Vision

Heinz Hügli, Alexandre Bur

The computer model of visual attention derives an interest or saliency map from an input image in a process that encompasses several data combination steps. While several combination strategies are possible, not all perform equally well. This paper compare ...
