Hydrogel-Encased Photonic Microspheres with Enhanced Color Saturation and High Suspension Stability
Regular arrays of colloidal particles can produce striking structural colors without the need for any chemical pigments. Regular arrays of colloidal particles can be processed into microparticles via emulsion templates for use as structural colorants. Phot ...
Washington2023Design of Energy-Efficient Discrete Cosine Transform using Pruned Arithmetic Circuits
Christian Enz, Vincent Frédéric Camus, Jérémy Lucien Maurice Schlachter
Inexact circuits and approximate computing have been gaining a lot of interest in order to improve performances and energy efficiency beyond the boundaries of conventional digital circuits. Image and video processing is one of the best candidate for applyi ...
IEEE2016Subjective Quality Evaluation of High Dynamic Range Video and Display for Future TV
Touradj Ebrahimi, Philippe Hanhart
The main objective of this paper is to verify test methodologies for the assessment of high dynamic range (HDR) video. To achieve this, a next generation HDR monitor by Dolby Laboratories was used to display professionally produced HDR content. Two complem ...

2014Quality assessment of multidimensional video scalability
Touradj Ebrahimi, Francesca De Simone, Jong Seok Lee
Scalability is a powerful concept for adaptive video content delivery to many end users having heterogeneous and dynamic characteristics of networks and devices. In order to maximize users' quality of experience by selecting appropriate combinations of mul ...
Institute of Electrical and Electronics Engineers2012High Power Blue-Violet Superluminescent Light Emitting Diodes with InGaN Quantum Wells
Nicolas Grandjean, Jean-François Carlin, Eric Feltin, Julien Dorsaz, Antonino Francesco Castiglia, Gatien Cosendey, Marco Rossetti
We report on the characteristics of blue superluminescent light emitting diodes based on the emission of InGaN quantum wells. Narrow ridge-waveguide devices realized by standard processing techniques and with extremely low facet reflectivity show single la ...
2010Sensing and Recovery under Sparsity Constraints
Popular transforms, like the discrete cosine transform or the wavelet transform, owe their success to the fact that they promote sparsity. These transforms are capable of extracting the structure of a large class of signals and representing them by a few t ...
EPFL2010Improved Side Information Generation for Distributed Video Coding by Exploiting Spatial and Temporal Correlations
Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret
Distributed Video Coding (DVC) is a new paradigm in video coding, which is receiving a lot of interests nowadays. Side Information (SI) generation is a key function in the DVC decoder, and plays a key-role in determining the performance of the codec. This ...
2009Distributed coding of Highly correlated image sequences with motion-compensated temporal wavelets
This paper discusses robust coding of visual content for a distributed multimedia system. The system encodes independently two correlated video signals and reconstructs them jointly at a central decoder. The video signals are captured from a dynamic scene ...
2006Image/video representation and scalable coding using redundant dictionaries
Compact or efficient representation for either images or image sequences is key operation to performing image and video processing tasks, such as compression, analysis, etc. The efficiency of an approximation is evaluated by the sparsity measure of the app ...
