Workshop on Transforms and Filter Banks

Second International Workshop on Transforms and Filter Banks will be arranged on March 5 – 7, 1999 by Fachhochschule Brandenburg, University of Applied Sciences in Brandenburg an der Havel, Germany. Chairman of the workshop is Prof. Reiner Creutzburg and Co-Chair Prof. Jaakko Astola.

First International Workshop on Transforms and Filter Banks was arranged last year by TICSP at Tampere University of Technology. The purpose of WTFB is to collect together some of the leading experts working in these areas and to talk about the most import issues in these fields. One of the goals is to establish a common language between the "transform people" and the "filter bank people" in order to generate fruitful discussions on the connections between transforms and filter banks. About 35 participants from 15 different countries have registered to the workshop.

TICSP Publication Series

TICSP has launched a new publication series. Two publications have already been printed and are available at TICSP:

Proceedings of First International Workshop on Transforms and Filter Banks Edited by J. Astola and R. Creutzburg					Target Location: Accuracy, Reliability and Optimal Adaptive Filters by Leonid P. Yaroslavsky, 1998.

Visitors to TICSP

Theodor Krenkel

Prof. Theodor Krenkel from Moscow Technical University of Communications and Informatics visited TICSP during the period of January 7 – February 6, 1999. Prof. Krenkel received the degrees of M.Sc., Ph.D. and Doctor of Science from Moscow Institute of Communications (MTUCI) in 1962, 1969 and 1991 respectively in radio engineering and computer science.

From 1969 to 1973 Prof. Krenkel held the position of Assistant Professor at the Department of Mathematics, and from 1974 he has acted as Associate Professor and Professor at the Department of Applied Mathematics and Computer Science of MTUCI.

Prof. Krenkel’s research interests include non-Euclidean conformal field theory, new mathematical techniques in image processing, morphogenetic models in economics and fractal analysis of images derived from stock, future and financial markets.

During his short visit Prof. Krenkel gave two presentations.

Dan Stefaniou

Dr. Dan Stefanoiu is currently affiliated to Politehnica University of Bucharest, Department of Automatic Control and Computer Science, where he works as a conference master. He visited TICSP on January 12 – March 9, 1999.

In 1986 Dr. Stefanoiu received the M.Sc. degree in automatic control and computers from Politehnica University of Bucharest and in 1993 in mathematics at the University of Bucharest. The Ph.D. degree he obtained in 1995 from Politehnica University of Bucharest on the subject "Time-Frequency Signal Analysis". In 1992, 1994 and 1995 he was an invited researcher and professor at Institut de la Communication Parlée of Grenoble. He gave also courses in Signal Processing for graduate students at Institut National Polytechnique of Grenoble.

His main fields of research interests are applied mathematics in signal processing and system identification, time-frequency and time-scale signal analysis (especially wavelets), data compression as well as speech processing and coding.

During his visit to TICSP he focused on a link between some results in discrete-time wavelets theory and the design of non-uniform filter banks with variable (signal dependent) filtering cells aimed to maximize the coding gain.
