Bonjour
Veuillez trouver ci-apres un appel a communication pour le numero special de
la revue "Signal Processing"
Advances in Multirate Filter Bank Structures and Multiscale Representations
Cordialement
******************************
A century after the first outbreak of wavelets in Alfred Haar's thesis in
1909, and twenty years after the advent of Multiresolution Analysis, filter
banks and wavelet transforms lie at the heart of many digital signal
processing and communication systems. During the last thirty years, they have
been the focus of tremendous theoretical advances and practical applications
in a growing digital world. They are for instance present, as local linear
expansions, at the core of many existing or forthcoming audio, image or video
compression algorithms.
Beyond standards, many exciting developments have emerged in filter banks and
wavelets from the confrontation between scientists from different fields
(including signal and image processing, computer science, harmonic analysis,
approximation theory, statistics, bioengineering, physics,...). At their
confluence, multiscale representations of data, associated with their
efficient processing in a multirate manner, have unveiled tools or refreshed
methods impacting the whole data management process, from acquisition to
interpretation, through communications, recovery and visualization. Multirate
structures naturally shelter key concepts such as the duality between
redundancy and sparsity, as well as means for extracting low dimensional
structures from higher ones. In image processing in particular, various
extensions of wavelets provide smart linear tools for building insightful
geometrical representations of natural images.
The purpose of this special issue is to report on recent progresses performed
and emerging trends in the domain of multirate filter banks and multiscale
representations of signals and images. Answers to the challenge of handling
an increasing demand of information extraction and processing from large data
sets will be explored.
