Research activity in 2000

The research has been carried on pluridimensional signals involving images and sound. In the images area the interest is focused on three main subjects: pattern recognition, compression and images’ synthesis. The first subject has been applied to biomedical and pictorial images while the two others are referred to virtual reality domain.

The main topics of the research are:

  1. improvement and study of new pattern recognition algorithms applied to biomedical, archaeological and pictorial images;

  2. compression and reconstruction of static images and movies, both monochromatic and coloured, using Loeve Karhunen expansion based on universal set of eigenvalue functions;

  3. project of prototypal virtual reality modules;

  4. study and creation of hypermedial didactical modules for children;

  5. application of image processing technique in forensic medicine;

  6. real time integration of virtual and real distributed environments;

  7. real time sound rendering for applications in virtual reality;

  8. transcoding and transmission of MPEG-2 video streams.

Multimedia Software Products

The ADDIZIONARIO project is a hypermedia linguistic laboratory to help children in the process of first language learning, in particular through the use of a multimedia dictionary. This software, developed in cooperation with the Institute for Computational Linguistics of CNR, was patented during 2000.
