Dynamic and active pixel vision sensors (DAVISs) are a new type of sensor that combine a frame-based intensity readout with an event-based temporal contrast readout. This paper demonstrates that these sensors inherently perform high-speed, video compressio ...
A method of providing SVC video content with added media content, comprising the steps of: receiving an original video content transmitted from a remote site in a bit stream and including original video encoding parameters decoding said original video enco ...
In this paper, we describe a real-time multimodal analysis system with just-in-time multimodal association and fusion for a living room environment, where multiple people may enter, interact and leave the observable world with no constraints. It comprises ...
We propose and analyze an online algorithm for reconstructing a sequence of signals from a limited number of linear measurements. The signals are assumed sparse, with unknown support, and evolve over time according to a generic nonlinear dynamical model. O ...

Current increasing effort of broadcast providers to transmit UHD (Ultra High Definition) content is likely to increase demand for ultra high definition televisions (UHDTVs). To compress UHDTV content, several alter- native encoding mechanisms exist. In add ...
Ultra High Definition (UHD) is one of the emerging immersive video technologies already available to public, as even some of the smartphones are capable of capturing UHD video. The increasingly widespread availability of UHD capable recording devices has i ...
Optimization of multimedia transmissions over wireless channels should be aimed at maximizing the video quality perceived by the final user. For transmission of video sequences over an orthogonal frequency division multiplexing (OFDM) system in a slowly va ...
We consider a multiuser OFDM system in which users want to transmit videos via a base station. The base station knows the channel state information (CSI) as well as the rate distortion (RD) information of the video streams and tries to allocate power and s ...

Multiple loci of control is one of the main affordances of tangible tabletop UIs due to their capability for simultaneous manipulation. However, there is a tension between the efficiency given by simultaneous manipulation and the need to coordinate and ref ...
