The Department is involved in basic research in image processing and pictorial pattern recognition. Major application areas are biomedicine, remote sensing, astronomy, and art conservation.

Main scientific areas
  • Recognition of distorted images and patterns by invariant descriptors regardless of their actual position in the scene
  • Registration and fusion of several images of the same scene taken at different times, by different sensors and/or from different viewpoints in order to obtain information of higher quality
  • Theory of moment invariants, namely of rotation invariants, affine invariants and invariants to convolution
  • Restoration of degraded images, namely multichannel blind deconvolution, edgepreserving denoising, local contrast enhancement, and color transformations
  • Image forensics - detection of image forgeries

The research in linear control theory has a long tradition at the Institute. In early 1960s, under the guidance of Professor Strejc, researchers at the Institute made considerable developments in both transfer-function and state-space methods. In the 1970s and the 1980s, the members of the Department, led by Professor Kučera, achieved significant results, which launched an entirely new area of research worldwide. Among these are the parametrization of all controllers stabilizing a given plant (known as the Youla-Kučera parametrization) and the design of control systems via polynomial equations. In the 1990s, the research activities of the department ranged from robust control to nonlinear systems.

Applied research in the department focuses on numerical methods for control-system simulation and design, which yields various original software packages for control and simulation. The current research objectives in the Department of Control Theory, which has been led by Sergej Čelikovský since 2004, are the analysis and design of control systems on the one hand and the topological study of dynamical systems on the other. The four main research directions are:

  • Analysis and design of linear systems including robust control.
  • Numerical methods for control systems analysis and design including chaotic systems.
  • Analysis and design of nonlinear control systems.
  • Topological dynamics and dynamical systems on surfaces and manifolds.
Interest is focused on both theoretical studies and computer implementation of the results obtained.

Blind Source Separation

Blind Source Separation consists of recovering original signals from their mixtures when the mixing process is unknown. In biomedicine, namely in MEG and EEG signal processing, one of the most popular algorithms nowadays is SOBI (Second Order Blind Identification).

The Department of Adaptive Systems focuses predominantly on the design of decision-making systems, which modify their behavior according to the changing properties of their environment. This essential ability – adaptivity – enhances their efficiency. Decades of research have brought a number of conceptual, theoretical, algorithmic, software and application results. The applicability of adaptive systems is currently being extended toward complex scenarios by improving the classical adaptive systems and by developing their new versions.

The departmental “know-how” serves to resolve national as well as international research projects, running in collaboration with industry and government agencies. The interplay between theory and limited computing power is the common issue linking the various project domains. They include traffic control, management and control of technological systems, radiation protection, nuclear medicine, analysis of financial data, electronic democracy, etc. The increasing complexity of the problems addressed directs the main stream of the research toward decentralized control of large-scale systems and normative decision-making with multiple participants.
