Recently, short animated image sequences have become very popular in social networks. Most animated images are represented in GIF format. In this paper we propose an animated JPEG format, called aJPEG, which allows the standard JPEG format to be extended i ...

What is the gamma gamma resonance at 750 GeV?

Riccardo Rattazzi, Francesco Riva, Roberto Franceschini, Michele Redi, Riccardo Torre

Run 2 LHC data show hints of a new resonance in the diphoton distribution at an invariant mass of 750 GeV. We analyse the data in terms of a new boson, extracting information on its properties and exploring theoretical interpretations. Scenarios covered in ...

The JPEG XT Suite of Standards: Status and Future Plans

Touradj Ebrahimi

The JPEG standard has known an enormous market adoption. Daily, billions of pictures are created, stored and exchanged in this format. The JPEG committee acknowledges this success and spends continued efforts in maintaining and expanding the standard speci ...

Overview and Evaluation of the JPEG XT HDR Image Compression Standard

Touradj Ebrahimi, Philippe Hanhart

Standards play an important role in providing a common set of specifications and allowing inter-operability between devices and systems. Until recently, no standard for High Dynamic Range (HDR) image coding had been adopted by the market, and HDR imaging r ...

Creativity without critique: An inquiry into the aesthetization of the alternative culture

Luca Giovanni Pattaroni, Yves Pedrazzini, Mischa-Sébastien Piraud, Letícia Cabeçadas Do Carmo

The category of “creative city” is far from neutral. Indeed, it can be linked to very contrasted – and even opposed – practices and urban worlds. In order to grasp those differences, we need to take a closer look at what is entailed in the concepts of “cre ...

ALLARM: Optimizing Sparse Directories for Thread-Local Data

Amitabha Roy

Large-scale cache-coherent systems often impose unnecessary overhead on data that is thread-private for the whole of its lifetime. These include resources devoted to tracking the coherence state of the data, as well as unnecessary coherence messages sent o ...

Design and Characterization of a Full-Duplex Multiantenna System for WiFi Networks

Vaneet Aggarwal

In this paper, we present an experiment-and simulation-based study to evaluate the use of full duplex (FD) as a potential mode in practical IEEE 802.11 networks. To enable the study, we designed a 20-MHz multiantenna orthogonal frequency-division-multiplex ...

JPEG backward compatible format for 3D content representation

Touradj Ebrahimi, Philippe Hanhart, Martin Rerabek

Different formats and compression algorithms have been proposed for 3D video content, but 3D images are still mostly represented as a stereo pair only. However, for enhanced 3D rendering capabilities, such as depth perception adjustment or display size ada ...

Context-dependent JPEG backward-compatible high-dynamic range image compression

Touradj Ebrahimi

High Dynamic Range (HDR) imaging is expected, together with ultra-high definition (UHD) and high frame rate (HFR) video, to become a technology that may change photo, TV, and film industries. Many cameras and displays capable of capturing and rendering bot ...

Analysis-suitable T-splines of arbitrary degree: definition, linear independence and approximation properties

Annalisa Buffa, Rafael Vazquez Hernandez

T-splines are an important tool in IGA since they allow local refinement. In this paper we define analysis-suitable T-splines of arbitrary degree and prove fundamental properties: Linear independence of the blending functions and optimal approximation prop ...
