In this paper we present a collision avoidance system based on visual detection. Our hardware consists of a Hummingbird quadrotor equipped with a large red marker with two built-in fish-eye cameras. Fusion of the measurements from the two cameras is done u ...
In this paper, we investigate the influence of music on human walking behaviors in a public setting monitored by surveillance cameras. To this end, we propose a novel algorithm to characterize the frequency and phase of the walk. It relies on a human-by-de ...
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 ...
Free-viewpoint television is expected to create a more natural and interactive viewing experience by providing the ability to interactively change the viewpoint to enjoy a 3D scene. To render new virtual viewpoints, free-viewpoint systems rely on view synt ...
We propose a novel method to automatically detect and extract the video modality of the sound sources that are present in a scene. For this purpose, we first assess the synchrony between the moving objects captured with a video camera and the sounds record ...

Ce projet prend place dans le cadre du programme Turbhélios qui vise à concevoir un prototype de centrale thermique hybride utilisant l’énergie solaire et le gaz. Ce rapport porte sur la partie commande et structure des héliostats. Il décrit la conception ...
Interactive free viewpoint video offers the possibility for each user to independently choose the views of a 3D scene to be displayed at de- coder. The visual content is commonly represented by N texture and depth map pairs that capture different viewpoint ...
Neuromorphic spike event-based dynamic vision sensors (DVS) offer the possibility of fast, computationally efficient visual processing for navigation in mobile robotics. To extract motion parallax cues relating to 3D scene structure, the uninformative came ...
This paper discusses how realtime face tracking and performance-based animation can facilitate new ways of interaction for computer gaming and other online applications. We identify a number of requirements for realtime face capture and animation systems, ...
In this paper, the analysis of a subjective quality experiment consisting in assessing the quality of free-viewpoint video sequences generated from decompressed depth data is presented. In the absence of a dedicated subjective assessment protocol for the e ...
