| Digital signal and image processing |

(DSP) represents a
very general discipline that joins completely different topics of
scientific research using very similar mathematical tools and algorithms.
In this way it corresponds to the vision of a very famous philosopher G. W.
Leibnitz (1646-1716) who tried to find the joint basis of different
scientific disciplines to minimize communication problems of specialists
of different areas of science. The feature of DSP as a link between
different scientific problems is emphasized also now in papers of
Prof. B. Widraw devoted to artificial neural networks.
In the modern world digital signal processing forms a basis for different
research areas including information engineering, measuring engineering,
control engineering, communication technologies, technical cybernetics and
biomedical engineering. The major research topics of the DSP group cover both
theoretical methods including signal decomposition and reconstruction based
on the Wavelet transform and applications in different areas.

| Biomedical Image Processing and Classification |
|
Methods of image analysis and their linear and non-linear processing
are used to perform signal de-noising, enhancement, detection of its
components and their identification. The goal is in biomedical (NMR)
image processing using Wavelet image decomposition and reconstruction,
spline interpolation and gradient methods.

| Environmental Image Analysis and Processing |
|
Project goal is in image analysis, correlation and de-noising
by two-dimensional Wavelet transform. Application is in the
detection of dust particles by satellite observations and
verification of suggested methods and algorithms by ground
measuring stations.
