Resumen
La
mayoría de los métodos estadísticos en procesado
de señal están basados en las hipótesis de
linealidad y estacionareidad de los
datos. Sin embargo existen un gran número de situaciones en las
cuales dichas
hipótesis dejan de ser válidas. Una manera de poder
resolver éste tipo de
problemas consiste en combinar un análisis basado en
representaciones conjuntas
con otro tipo de técnicas tales como redes neuronales,
análisis en componentes
principales, etc. En este seminario se introducirán las
principales técnicas de
representación conjunta tales como la distribución de
Wigner-Ville, se
presentarán algunas aplicaciones donde el uso de este tipo de
métodos ha sido
particularmente útil y se comparará con otro tipo de
técnicas de uso
generalizado como las basadas en wavelets.
Gabriel Cristóbal
Gabriel Cristóbal received the MSc and PhD degrees both in
telecommunication engineering from the Universidad Politecnica of
Madrid, Spain, in 1979 and 1986, respectively. He is currently a
research scientist at the Instituto de Optica, Spanish Research Council
(CSIC). He was a postdoctoral fellow at the international Computer
Science Institute and the Electronic Research Laboratory (University of
California, Berkeley) from 1989 to 1992. His current research interests
are in joint representations, vision modeling, and image compression.
He has published more than 40 papers in technical journals and
conferences. He has been responsible for several national and EU
research and development projects. He is a Senior Member of the IEEE
and a member (and head of the Spanish
delegation) of the ISO/IEC/SC29/WG01 JPEG 2000 Committee since 2000.
Filiop Sroubek
Filip Sroubek received the B.Sc. and M.Sc. degrees in computer science
from the Czech Technical University, Prague, Czech Republic, in 1996
and 1998, respectively, and is currently pursuing the Ph.D. degree in
computer science at the Charles University,
Prague. Since 1999, he has been with the Institute of Information
Theory and Automation, Academy of Sciences of the Czech Republic,
Prague. Since 2000, he has been with the Institute of Radiotechnique
and Electronics, Academy of Sciences of the Czech
Republic, Prague. From October 2004 is a posdoc fellow at the Instituto
de Optica (CSIC). His current research interests include all aspects of
digital image processing and pattern recognition, particularly
multichannel blind deconvolution, image denoising, image registration,
and computer simulation and visualization of atomic collision
processes.
