Abstract
Research activities of the group cover a number of interrelated topics that may be used in the field of transmission and processing of digitised multimedia data and signals. In the area of algorithmic theory for digital processing of multidimensional signals we are active on several types of processing, filtering, enhancement and encoding of static images. We are also active in the basic research of image compression methods, object recognition and enhancement, thus related also to the forthcoming standards for object-based encoding and video compression (MPEG4, MPEG7). Within this framework, we develop methods for non-linear image sharpening, wavelet-based image compression, image quality assessments, object recognition and optimal shape encoding. Besides, we also work on image encoding parameter optimisation related to image transfer over communication networks where dynamic network properties (network latencies, errors, bandwidth) are to be taken into account, thus addressing also some issues in network and service management. In the field of pattern recognition, a new theory of invariant transformations has been developed within our group. The group is also active in the field of parallel processing, where a massively parallel processor for multidimensional signal processing is being designed. In parallel, parallel processing matrix computational algorithms are being developed that enable complex real time image processing operations. As an extension to basic theoretical research, we also study new services that employ the mentioned approaches, with emphasis to mobile systems, communication network integration and service personalisation. In the communication services area, we work on network management for real time image transfer in high quality and for support of symmetrical and asymmetrical visual communication services. With user services, we are working also on user interface improvements and on interactive user and service management. As a test field, we promote new technologies used for remote education application. Our concept of remote education combines interactivity with the power of local storage to provide media rich educational environment. The concepts introduced are being extended to dedicated services like high-quality services in (tele)medicine. Our group is currently active on reconfigurable hardware architectures that may be used for system prototyping and evaluation, especially in the image-processing domain. The system is designed to enable hardware emulation and verification of complex digital structures before VLSI realisation. Partial research also covers user-friendly tools for circuit design, optimisation, synthesis and verification.
