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 ...
Research in the field of video quality assessment relies on the availability of subjective scores, collected by means of experiments in which groups of people are asked to rate the quality of video sequences. The availability of subjective scores is fundam ...
When a stereo pair is formed from a decoded view and a synthesized view, it is unclear how the overall quality of the stereo pair should be assessed through objective quality metrics. In this paper, this problem is addressed considering a 3D video represen ...
Dual eye tracking offers new possibilities for the analysis and diagnosis of collaborative interaction. Cross-recurrence analyses and visualizations offer insight into how closely two collaborators’ gaze follow each other. We contrast two cases to illustra ...
