Optimization Techniques and Variable Transformation for 2-D and 3-D Filter Design

Professor Nikos E. Mastorakis
Technical University of Sofia

Abstract: The Design of m-D (Multidimensional) Filters attracted much attention in Systems Theory and Digital Signal Processing due to great interest as well as numerous applications in Medical Data, Seismic Data and Satellite Data Processing, X-ray Enhancement, Pattern Recognition etc. In this Plenary lecture we present new 2-D and 3-D Filter Design techniques.
We present two major methodologies in m-d Filter Design: a) appropriate variable transformations and b) Optimization. Stability of m-D Filters is examined and ensured. The validity of the methods is proven and illustrated by various numerical examples.

Brief Biography of the Speaker: Prof. Dr. Nikos E. Mastorakis received his B.Sc. and M.Sc. (Diploma) in Electrical Engineering from the National Technical University of Athens (Greece) and the Ph.D. in Electrical Engineering and Computer Science from the same university. He also received the B.Sc. (Ptychion) in Pure Mathematics from the National University of Athens, Greece. He also studied Medicine in Medical School of Athens of the same university. He have served as special scientist on Computers and Electronics in the Hellenic (Greek) Army General Staff (1993-1994) and taught several courses in the Electrical and Computer Engineering Department of the National Technical University of Athens (1998-1994). He has also served as Visiting Professor at the University of Exeter, School of Engineering (UK, 1998), Visiting Professor in the Technical University of Sofia (Bulgaria, 2003-2004) while he is now Professor in the Technical University of Sofia (Bulgaria,, and and also Professor in the department of Computer Science at the Military Institutions of University Education (MIUE) -Hellenic Naval Academy, Greece.
Prof. Dr. Nikos Mastorakis was the first that solved with several different approaches the former unsolved problem of Multivariable Factorization and published it. He was also the first scholar that completely solved the problem of stability for Multidimensional Systems using Genetic Algorithms. Also, was the first that constructed Electronic Musical Instrument with the spaces of the Byzantine music. He is an active researcher in Applied Mathematics and Computer Science (Systems Theory, Control, Optimization Theory, Algorithms Theory, Signal Processing, Robotics, Computational Intelligence).
