On the significance of binning in a scaling-law sense

Michael Christoph Gastpar

An efficient distributed source coding system with two encoders and dependent data streams must remove two kinds of redundancy: redundancy in each stream and between the two streams. The striking result of Slepian and Wolf showed that the latter can be eli ...

Audio Coding Based on Long Temporal Segments: Experiments With Quantization of Excitation Signal

Petr Motlicek

In this paper, we describe additional experiments based on a novel audio coding technique that uses an autoregressive model to approximate an audio signal's Hilbert envelope. This technique is performed over long segments (1000 ms) in critical-band-sized s ...

Low rate and flexible image coding with redundant representations

Pascal Frossard, Pierre Vandergheynst

New breakthroughs in image coding possibly rely in signal decomposition through non-separable basis functions. The work proposed in this paper provides an adaptive way of representing images as a sum of two-dimensional features. It presents a low bit-rate ...

Media Aware Routing in Large Scale Networks with Overlay

Pascal Frossard, Dan Jurca, Sofija Petrovic

This paper presents a new routing strategy, that selects the best network paths in an overlay network, in order to minimize the distortion perceived by the end user. We first propose a model that reports the video distortion as a function of the encoding r ...

Multiresolution Motion Estimation for Omnidirectional Images

Pascal Frossard, Pierre Vandergheynst, Ivana Tosic, Iva Bogdanova Vandergheynst

This paper presents a novel local motion estimation algorithm for omnidirectional images. The algorithm captures correlation between two spherical images of a scene, taken from arbitrary viewpoints, with the objective to reduce the encoding rate of these i ...

Rate-distortion optimized geometrical image processing

Rahul Shukla

Since geometrical features, like edges, represent one of the most important perceptual information in an image, efficient exploitation of such geometrical information is a key ingredient of many image processing tasks, including compression, denoising and ...

Hierarchical Implicit Surface Joint Limits for Human Body Tracking

Pascal Fua, Raquel Urtasun, Lorna Herda

To increase the reliability of existing human motion tracking algorithms, we propose a method for imposing limits on the underlying hierarchical joint structures in a way that is true to life. Unlike most existing approaches, we explicitly represent depend ...

Adaptive video streaming in lossy networks: versions or layers?

Pascal Frossard, Ivana Radulovic

This paper tackles low delay adaptive video streaming over error-prone networks. Our framework consists of an encoding station, an edge server and a set of clients with various access rates. The edge server is capable of performing simple error concealment ...

JPEG2000: The upcoming still image compression standard

Touradj Ebrahimi

With the increasing use of multimedia technologies, image compression requires higher performance as well as new features. To address this need in the specific area of still image encoding, a new standard is currently being developed, the JPEG2000. It is n ...
