Data-Driven MRSI Spectral Localization Via Low-Rank Component Analysis

Dimitri Nestor Alice Van De Ville, Jeffrey Adam Kasten

Magnetic resonance spectroscopic imaging (MRSI) is a powerful tool capable of providing spatially localized maps of metabolite concentrations. Its utility, however, is often depreciated by spectral leakage artifacts resulting from low spatial resolution me ...

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 ...

Finite Rate of Innovation Based Modeling and Compression of ECG Signals

Gilles Baechler, Nikolaos Freris

Mobile health is gaining increasing importance for society and the quest for new power efficient devices sampling biosignals is becoming critical. We discuss a new scheme called Variable PulseWidth Finite Rate of Innovation (VPW-FRI) to model and compress ...

Correlation Estimation from Compressed Images

Pascal Frossard, Vijayaraghavan Thirumalai

This paper addresses the problem of correlation estimation in sets of compressed images. We consider a framework where images are represented under the form of linear measurements due to low complexity sensing or security requirements. We assume that the i ...

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 ...

Heat Transfer Modelling of a Co-rotating Scroll Compressor

Emil Shaykhilislamov

This report accounts for making the heat transfer model in co-rotating scroll compressor. This mathematical model was proposed according to the working principle of the compressor, its geometry and basic thermodynamics’ laws. Previous papers and reports, r ...

Effects of grain size and gradation on the dynamic responses of quartz sands

Jeffrey Huang, Sheng Xu

The dynamic compression responses of quartz sands of different grain sizes and gradations are tested with a modified spilt Hopkinson pressure bar in which a single-pulse loading system is implemented. The yield stresses, the compressibility and the energy- ...

Joint Reconstruction of Multi-view Compressed Images

Pascal Frossard, Vijayaraghavan Thirumalai

The distributed representation of correlated multi-view images is an important problem that arise in vision sensor networks. This paper concentrates on the joint reconstruction problem where the distributively compressed correlated images are jointly decod ...

Fast encoding techniques for Multiview Video Coding

Pascal Frossard

Multiview Video Coding (MVC) is a technique that permits efficient compression of multiview video. MVC uses variable block size motion and disparity estimation for block matching. This requires an exhaustive search process that involves all possible macro- ...
