TELIN/UGent/IR07
Currently, TELIN consists of the following research groups:
The group studies how to extend databases for dealing with fuzzy and uncertain information. This involves, on the one hand, the representation of fuzzy data and the adaptations of the existing database schema's. On the other hand, it involves the uncertainty as to the manipulation of the data studied. The modelling is based on the use of fuzzy set theory and the related possibility theory. Semantical aspects are studied in collaboration with a team of linguists. Most of the research up till now has been concerned with the extension of the ER-model and of object-oriented database models. For implementation purposes, some related research has been carried out.
The topics studied in the DIGCOM research group are: Modulation/Demodulation, Coding/Decoding, Carrier and Clock Synchronisation, and Equalization
Within the IPI research group the following topics are being studied: Watershed Based Segmentation, Content Based Image Retrieval, Edges and Line Detection, Model-Based Image Interpretation, Motion Estimation and Motion-Based Segmentation, Scale Space, Stereo Vision, Texture segmentation, Image processing techniques for the detection of buried landmines, Techniques for restoration and quantitative image analysis of medical ultrasound images, Compression of medical images and video
The main applications of the work done by this group are situated in the performance assessment of digital communication systems and networks. The research activities of the SMACS Research Group can be more or less divided in two parts. The major topic is the statistical analysis of buffers for the storage of digital information, by means of discrete-time queueing models. The second (minor) topic is the design, analysis and optimization of ARQ retransmission protocols.
