Reconfigurable media coding: a new specification model for multimedia coders

Multimedia coding technology, after about 20 years of active research, has delivered a rich variety of different and complex coding algorithms. Selecting an appropriate subset of these algorithms would, in principle, enable a designer to produce the codec ...

A Stochastic Model for Video and its Information Rates

Martin Vetterli, Minh Do

We propose a stochastic model for video and compute its information rates. The model has two sources of information representing ensembles of camera motion and visual scene data (i.e. "realities"). The sources of information are combined generating a vecto ...

Fault-Tolerant Multi-Level Logic Decoder for Nanoscale Crossbar Memory Arrays

Giovanni De Micheli, Mihai Adrian Ionescu, David Atienza Alonso, Didier Bouvet, Kirsten Emilie Moselund, Yusuf Leblebici

Several technologies with sub-lithographic features are targeting the fabrication of crossbar memories in which the nanowire decoder is playing a major role. In this paper, we suggest a way to reduce the decoder size and keep it defect tolerant by using mu ...

Image Coding of 3D Volume Using Wavelet Transform for Fast Retrieval of 2D Images

Vijayaraghavan Thirumalai

An encoder/decoder system for 3D volumetric medical data is proposed. The system allows fast access to any 2D image by decoding only the relevant information from each subband image and thus provides minimum decoding time. This will be of immense use for t ...

Juicer: A Weighted Finite-State Transducer speech decoder

John David Scott Dines, Darren Moore

A major component in the development of any speech recognition system is the decoder. As task complexities and, consequently, system complexities have continued to increase the decoding problem has become an increasingly significant component in the overal ...

Successive decoding

Ninoslav Marina

As the demand for wireless mobile communication services is constantly growing, the need for mobile systems and devices that support much higher data rates is increasing. The available bandwidth is limited and expensive, thus we need new technologies that ...

Perceptual Prefiltering for Video Coding

Touradj Ebrahimi

Semantic segmentation is generally associated with second generation video coders, or object-based coders. Object-based coders encode different video objects separately in order to achieve lower bitrates and to enable object-based functionalities. In this ...

Video quality evaluation for mobile applications

Frédéric Dufaux, Stefan Winkler

This paper presents the results of our quality evaluations of video sequences encoded for and transmitted over a wireless channel. We selected content, codecs, bitrates and bit error patterns representative of mobile applications and we concentrated on the ...

Multidomain pseudospectral time-domain simulations of scattering by objects buried in lossy media

Jan Sickmann Hesthaven

A multidomain pseudospectral time-domain (PSTD) method with a newly developed well-posed PML is introduced as an accurate and flexible tool for the modeling of electromagnetic scattering by 2-D objects buried in an inhomogeneous lossy medium. Compared with ...
