Feature integration across space, time, and orientation

The perception of a visual target can be strongly influenced by flanking stimuli. In static displays, performance on the target improves when the distance to the flanking elements increases-presumably because feature pooling and integration vanishes with d ...

Filling-in afterimage colors between the lines

Marcus Leonardus Vergeer

It is known that when a colored surface is viewed for some time and a blank screen is presented afterwards, an afterimage can be perceived in the complementary color. Color appearances in afterimages are due to adaptation of retinal cones and they are espe ...

Enhanced temporal but not attentional processing in expert tennis players

Michael Herzog, Olaf Blanke

In tennis, as in many disciplines of sport, fine spatio-temporal resolution is required to reach optimal performance. While many studies on tennis have focused on anticipatory skills or decision making, fewer have investigated the underlying visual percept ...

Neurocomputational modeling of imitation deficits

Aude Billard, Biljana Petreska von Ritter-Zahony

We are interested in the question of human imitation and we address this through convergent evidence from neuroscience. The rationale of our work is that the nature of imitation deficits following brain lesion can unveil some of the neural and computationa ...

Investigating Automatic Dominance Estimation in Groups From Visual Attention and Speaking Activity

Daniel Gatica-Perez, Jean-Marc Odobez, Silèye Oumar Ba, Dinesh Babu Jayagopi

We study the automation of the visual dominance ratio (VDR); a classic measure of displayed dominance in social psychology literature, which combines both gaze and speaking activity cues. The VDR is modified to estimate dominance in multi-party group discu ...

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 ...
