 Web & Multimedia Systems


Activities:

The web & multimedia systems group studies the performance of these systems, paying special attention to interactive systems on cable networks. Current subjects of research include workload characterization, development of performance models for cable networks and influence of media servers on the quality of interactive video-on-demand services.

 Image Processing Systems


Activities:

The image processing systems group has been developing special purpose imaging systems mainly based on linear scanners. Examples of the systems developed include flatness sensors based on laser triangulation techniques, shape classification systems with real-time adaptation to variable-luminance of inspected objects, and systems for acquisition and analysis of thermographic images. Current research is mainly focused on development of correlation techniques of thermographs with flatness measurements of steel strips.
