WILDTRACK: A Multi-camera HD Dataset for Dense Unscripted Pedestrian Detection

Pascal Fua, François Fleuret, Tatjana Chavdarova, Andrii Maksai, Cijo Jose

People detection methods are highly sensitive to occlusions between pedestrians, which are extremely frequent in many situations where cameras have to be mounted at a limited height. The reduction of camera prices allows for the generalization of static mu ...

Motor imagery in spinal cord injured people is modulated by somatotopic coding, perspective taking, and post-lesional chronic pain

Polona Pozeg

Motor imagery (MI) allows one to mentally represent an action without necessarily performing it. Importantly, however, MI is profoundly influenced by the ability to actually execute actions, as demonstrated by the impairment of this ability as a consequenc ...

Those are Your Legs: The Effect of Visuo-Spatial Viewpoint on Visuo-Tactile Integration and Body Ownership

Olaf Blanke, Polona Pozeg

Experiencing a body part as one's own, i.e., body ownership, depends on the integration of multisensory bodily signals (including visual, tactile, and proprioceptive information) with the visual top down signals from peripersonal space. Although it has bee ...

Characterizing Embodied Interaction in First and Third Person Perspective Viewpoints

Ronan Boulic, Bruno Herbelin, Eray Molla, Henrique Galvan Debarba

Third Person Perspective (3PP) viewpoints have the potential to expand how one perceives and acts in a virtual environment. They offer increased awareness of the posture and of the surrounding of the virtual body as compared to First Person Perspective (1P ...

Quality Assessment of a Stereo Pair Formed From Two Synthesized Views Using Objective Metrics

Touradj Ebrahimi, Philippe Hanhart

When a stereo pair is formed from two synthesized views, it is unclear whether objective 2D quality metrics can provide a good estimation of the perceived quality. In this paper, this problem is addressed considering a 3D video represented in multiview vid ...

MicroPlay: A Networking Framework for Local Multiplayer Games

Christina Fragouli, Lorenzo Keller

Smartphones are an ideal platform for local multiplayer games, thanks to their computational and networking ca- pabilities as well as their popularity and portability. How- ever, existing game engines do not exploit the locality of players to improve game ...

Quality Assessment of a Stereo Pair Formed From Decoded and Synthesized Views Using Objective Metrics

Touradj Ebrahimi, Philippe Hanhart

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 ...

Towards reliable and reproducible 3D video quality assessment

Touradj Ebrahimi, Lutz Goldmann

The success of 3D video, as one of the emerging multimedia formats, will largely depend on the improved quality of experience that it provides to viewers when compared to conventional 2D video. Therefore reliable methods for 3D video quality assessment are ...

Providing the best Third-Person Perspective to a Video-Through HMD

Daniel Thalmann, Frédéric Vexo, Patrick Salamin

This paper describes a system with several fixed cameras that provide Third-Person Perspective (3PP) to the video-through HMD of the user. Once done, our system uses an algorithm to make intelligent switches between the different cameras in order to provid ...

Quantifying effects of exposure to the third and first-person perspectives in virtual-reality-based training

Daniel Thalmann, Olaf Blanke, Frédéric Vexo, Patrick Salamin, Ravi Tej Sai Giridhar Tadi

In the recent years, usage of the third-person perspective (3PP) in virtual training methods has become increasingly viable and despite the growing interest in virtual reality and graphics underlying third-person perspective usage, not many studies have sy ...

Temporal Synchronization in Stereoscopic Video: Influence on Quality of Experience and Automatic Asynchrony Detection

Touradj Ebrahimi, Jong Seok Lee, Lutz Goldmann

In this paper, we analyze the inﬂuence of temporal asyn- chrony on the subjective quality of stereoscopic video. Based on our recently created 3D video database, different levels of asynchrony were simulated and a comprehensive subjective test was conducte ...

Learning from animation enabled by collaboration

Pierre Dillenbourg

Animated graphics are extensively used in multimedia instructions explaining how natural or artificial dynamic systems work. As animation directly depicts spatial changes over time, it is legitimate to believe that animated graphics will improve comprehens ...

Intelligent switch: An algorithm to provide the best third-person perspective in augmented reality

Daniel Thalmann, Frédéric Vexo, Patrick Salamin

Augmented reality (AR) environments are suffering from a limited workspace. In addition, registration issues are also increased by the use of a mobile camera on the user that provides a first-person perspective (1PP). Using several fixed cameras reduces th ...

Characterizing full-body reach duration across task and viewpoint modalities

Daniel Thalmann, Ronan Boulic, Damien Maupu

The full-body control of virtual characters is a promising technique for application fields such as Virtual Prototyping. However it is important to assess to what extent the user full-body behavior is modified when immersed in a virtual environment. In the ...

Improved Third-Person Perspective: a solution reducing occlusion of the 3PP?

Daniel Thalmann, Frédéric Vexo, Patrick Salamin

Pre-existing researches [Salamin et al. 2006] showed that Third-Person Perspective (3PP) enhances user navigation in 3D virtual environments by reducing proprio-perception issues. Nevertheless, this approach has shown drawbacks related to occlusions and ad ...

The Benefits of Third-Person Perspective in Virtual and Augmented Reality?

Daniel Thalmann, Frédéric Vexo, Patrick Salamin

Instead of the reality in which you can see your own limbs, in virtual reality simulations it is sometimes disturbing not to be able to see your own body. It seems to create an issue in the proprioperception of the user who does not completely feel integra ...
