Role and contribution

The role of DISI in the project is primarily concerned with software design and development. DISI will contribute regarding 3D reconstruction and mosaicing from range data, multiresolution modelling and augmented reality visualisation. In particular, DISI is responsible for WP5, and it contributes heavily in WP6. Moreover, it will contribute in the system specification, integration and validation activities.

   

Qualification

DISI (Dipartimento di Informatica e Scienze dell'Informazione), the Department of Computer and Information Sciences of the University of Genova, has been established in 1992. It has been rapidly growing and its teaching and research staff consists presently of 24 people, among which 8 full professors, plus about 20 PhD students involved in research activities. The main research areas at DISI include Formal Methods, Computer Graphics and Computational Geometry, Object Oriented and Logic Programming, Performance Evaluation, Semantics and Logic, Databases and Information Systems, Design and Implementation of Languages and Systems.

DISI and its members are actively engaged in many national and international research projects (both with academia and industry), among which Esprit BR WG APPSEM, Esprit BRA POSSO, Esprit BR WG ISCORE, HCM EXPRESS, HPRN MINGLE; some notable projects in the past are Brite BRA VENICE, HCM SPACENET, HCM MEDICIS, Esprit BR WG COMPASS, Esprit BRA CLICS, HCM MATCH, MAP project on ADA Formal Definition, and Esprit DRAGON.  There are also some strong connections and collaborations with research centres in the United States, in particular with SRI (Stanford Research Institute), Department of Computer Science of the University of Maryland, and Rensselaer Polytechnic Institute.

The Computer Graphics and Geometric Modelling Group at DISI has several years of expertise and is widely known in the international scientific community. In particular, the group is well-known for its research activities in: the design of multiresolution models and data structures for representation and manipulation of solid objects and surfaces; the reconstruction of 3D surfaces and object models from sampled data; the design of geometric models and algorithms for applications in Geographical Information Systems; the development of sophisticated tools for 3D data visualisation.
