Hybrid Coding Scheme for Brillouin Optical Time-domain Analysis Based on Golay and Differential Pulses

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Zhisheng Yang, Zonglei Li

A hybrid Golay coding method based on differential pulse-pair sequences is proposed for distributed Brillouin sensing. The method provides 1.5 dB signal-to-noise ratio improvement over unipolar Golay with halved measurement time, securing high spatial reso ...

A Hybrid Approach for Efficient Color Gamut Mapping

Ultra High Definition (UHD) and High Definition (HD) Television standard recommendations support different color gamuts with the HD gamut much smaller than that of the UHD one. To adapt UHD content to the restricted gamut of HD televisions, a process known ...

Evaluation of Color Mapping Algorithms in Different Color Spaces

Touradj Ebrahimi

The color gamut supported by current commercial displays is only a subset of the full spectrum of colors visible by the human eye. In High-Definition (HD) television technology, the scope of the supported colors covers 35.9% of the full visible gamut. For ...

Extension of Fourier-based techniques for ultrafast imaging in ultrasound with diverging waves

Jean-Philippe Thiran, Rafael Eduardo Carrillo Rangel, Adrien Georges Jean Besson, Olivier Bernard, Damien Garcia

Ultrafast ultrasound imaging has become an intensive area of research thanks to its capability in reaching high frame rates. In this paper, we propose a scheme which allows the extension of the current Fourier-based techniques derived for planar acquisitio ...

Towards prediction of Sense of Presence in immersive audiovisual communications

Touradj Ebrahimi, Martin Rerabek, Anne-Flore Nicole Marie Perrin

Tremendous progress has been made in audiovisual technologies in the last decades. Consequently, new technologies quality measures evolve and trend to be more user-centric. This is the reason why the Quality of Experience (QoE) assessment is presently mean ...

Nonstationary flow surface theory for modeling the viscoplastic behaviors of soils

Lyesse Laloui, Alessio Ferrari, Yafei Qiao

This paper presents a three-dimensional elastic viscoplastic model that can describe the time-dependent behaviors of soft clays. The constitutive model is formulated based on the nonstationary flow surface theory and incorporates new developments, includin ...

A sparse regularization approach for ultrafast ultrasound imaging

Jean-Philippe Thiran, Yves Wiaux, Rafael Eduardo Carrillo Rangel, Adrien Georges Jean Besson, Olivier Bernard

Ultrafast imaging based on plane-wave (PW) in- sonification is an active area of research due to its capability of reaching high frame rates. Several approaches have been proposed either based on either of Fourier-domain reconstruction or on delay-and-sum ...

H2B2VS (HEVC Hybrid Broadcast Broadband Video Services) – building innovative solutions over hybrid networks

Claudio Paolo Alberti

Broadcast and broadband networks continue to be separate worlds in the video consumption business. Some initiatives such as HbbTV have built a bridge between both worlds, but its application is almost limited to providing links over the broadcast channel t ...
