Fractal additive synthesis

Pietro Polotti

Musical and audio signals in general form a major part of the large amount of data exchange taking place in our information-based society. Transmission of high quality audio signals through narrow-band channels, such as the Internet, requires refined metho ...

Oligoquantization in low-rate lossy source coding

The theory of high rate lossy source coding is well developed both with respect to the practice of quantization and its fundamental rate distortion limits. But many modern compression systems for natural signals such as audio and images operate at lower ra ...

Optimal Scheduling of Rich Media in a Rate-Distortion Sense

Pascal Frossard

We consider the transmission of variable bit rate video over a network offering a guaranteed service such as ATM VBR or the guaranteed service of the IETF. The guaranteed service requires that the flow accepted by the network has to be conforming with a tr ...

Optimal Filter Banks for Multiple Description Coding: Analysis and Synthesis

Martin Vetterli, Pier Luigi Dragotti

Multiple description (MD) coding is a source coding technique for information transmission over unreliable networks. In MD coding, the coder generates several different descriptions of the same signal and the decoder can produce a useful reconstruction of ...

The distributed Karhunen-Loeve transform

Martin Vetterli, Michael Christoph Gastpar, Pier Luigi Dragotti

The Karhunen-Loeve transform is a key element of many signal processing tasks, including classification and compression. In this paper, we consider distributed signal processing scenarios with limited communication between correlated sources, and we invest ...

Predicting Nonlinear Distortion in Common-Emitter Stages for Amplifier Design Using Volterra Series

Martin Hasler, Oscar De Feo

In this paper we present a method for predicting nonlinear distortion in electronic circuits using the Volterra series. Simple expressions for the distortion in a Common-Emitter stage are determined. Designers may use these expressions to get a quick insig ...

Lossy to lossless object-based coding of 3-D MRI data

Jean-Philippe Thiran, Gloria Menegaz

We propose a fully three-dimensional object-based coding system exploiting the diagnostic relevance of the different regions of the volumetric data for rate allocation. The data are first decorrelated via a 3D discrete wavelet transform. The implementation ...

To Code, Or Not To Code: On the Optimality of Symbol-by-Symbol Communication

Martin Vetterli, Michael Christoph Gastpar, Bixio Rimoldi

When is uncoded transmission optimal? This paper derives easy-to-check necessary and sufficient conditions that do not require finding the rate-distortion and the capacity-cost functions. We consider the symbol-by-symbol communication of discrete-time memo ...

Soft ARQ for layered streaming media

Martin Vetterli

A growing and important class of traffic in the Internet is so-called `streaming media,' in which a server transmits a packetized multimedia signal to a receiver that buffers the packets for playback. This playback buffer, if adequately sized, counteracts ...

Joint Smoothing and Source Rate Selection for Guaranteed Service Networks

Pascal Frossard, Jean-Yves Le Boudec, Olivier Verscheure

We consider the transmission of variable bit rate (VBR) video over a network offering a guaranteed service such as ATM VBR or the guaranteed service of the IETF. The guaranteed service requires that the flow accepted by the network has to be conforming wit ...
