My research interests are in the field of image synthesis, image processing, human computer interaction, visual communication and visual perception. Current and past research projects carried on at the Laboratory of Eidomatics are:

This research line aims at improving photorealistic image synthesis algorithm taking into account, in particular, the characteristics of light sources and their description in terms of colorimetric and photometric parameters. This aims both at increasing image quality and simplifying human interface to define image control parameters. Algorithmic approach focuses on ray tracing and radiosity methods.

In co-operation with CCR research centre, ISEI - Image laboratory, I have worked on improving methods for optical field computation, aiming at a new method to generate interference holograms.

I have been working until 1994 on parallelisation of ray tracing and radiosity algorithms, adopting multiprocessing architecture: KSR shared memory systems and Meiko Transupter based distributed memory system.

I have coordinated a research project for advanced modelling of environmental data, in particular my research group is developing algorithms and methods to approximate, with fractal geometry technique, a digital terrain model. Also photorealistic image synthesis is applied to increase DTM rendering.

I have coordinated a research project on image compression methods, in particular my research group is working on improving and optimizing IFS based fractal compression methods to code and compress medical, satellite and computer generated images.

At the Laboratory of Eidomatics we have implemented a computer system to visualise volumetric data sets for non destructive evaluation in industrial field. The system XEVA-VisualStudio, is currently being used by researchers in biological and medical fields, and is distributed and supported as public domain software by the laboratory.

I have coordinated a research activity which aims at providing diagnostical and surgical planning tools for orthodontics, based on volume imaging techniques. In particular I am currently working on innovative algorithms for volume data classification, based on fuzzy logic.

I have coordinated a research activity to develop GEObject, a computer system for geometric modelling, based on Object Oriented methodology and mimicing compass and ruler approach to constructive geometry. The prototypal software version of GEObject is available. This activity is part of a co-operation with the research group of prof. Didier Arques at the Université of Marne la Vallée, where this approach is used to implement a computer animation system.

I am coordinating a research activity to develop a computational model of human colour vision to improve colour reproduction, particularly for photorealistic image synthesis. The method and algorithms are based on Edwin Land's Retinex theory.

I am working on problems of design of visual communication systems. The focus of my interest and experience is in the area of distributed multimedia systems, adopting virtual reality and Web based techniques. Past projects were: an experimental Web site for the restoration of the ancient roman theatre of the town of Aosta, and the official web si te of Teatro alla Scala of Milano.

All the software systems and algorithms below have been implemented with the collaboration of undergraduate and post graduate students at the Dept. of Information Sciences, under my co-ordination and direction. This software is available as public domain, by connecting to the Web Site of Laboratory of Eidomatics: ttp://escher.usr.dsi.unimi.it/imaging or by direct request.

This is an interactive systems running on a variety of Unix based workstation, to visualise and explore volumetric data sets, by adopting voxel based volume rendering techniques. XEVA runs on standard Unix based platforms with Motif interface; a PVM version has been implemented by CSCS at Manno; new improvements are being developed by other users across the world.

Multiple versions of ray tracing Lighter software have been implemented. They support the following illumination models: Whitted, Cook & Torrance, Modified Cook & Torrance with Retinex colour computation.

The different versions of Lighter run on standard Unix platforms, on PC and on KSR and MEIKO parallel computer systems. Lighter can render any solid model created using Autcad modelling system; an interface with CADLAB Eureka system is on going. This software is available upon request.

This software renders surface based models created using Autocad geometric modelling system, and generates VRML compatible files that can be visualised using any VRML viewer. Lighter_radiance adopts different techniques to compute view factor: Malley, Hemi-Cube and approximated Stokes. This software is available upon request.

This software system models geometric objects by object oriented methodology. It allows to establish constraints among objects, that are maintained without any numerical constraint solution method. This allows a user to implement direct and inverse cinematics. A version implemented using Eiffel Language is available upon request, or for testing by remote WEB connection, only for HP 9000/700 platforms. A new version based on Java Language is being implemented.

This system supports multiple colour operation following Retinex theory of human colour visual perception. It can be integrated into a visualisation pipe-line or used stand-alone to filter a coloured image for display or printing. This software is not yet available being under debugging and optimisation.

I have been active on education since my degree, participating in many initiatives, lectures, seminars, conferences, tutorial on topics rangin from software quality control to computer gaphics, image processing and human computer interaction. These tutorial and courses have been organised by many private and public insitutions like, to mention only some of them: CILEA, Etnoteam Spa, Scuola Superiore "G. Reiss Romoli".

An important education program under my co-ordination and project has been a program for young under occupied people, financed by Regione Lombardia and European Social Fund, to give a professional background on computer imaging techniques. This annual, full time program has been repeated three times, form 1984 until 1986.

The editorial activity has been focused on dissemination of computer graphics and computer imaging techniques, methodology and applications. I have been among the founders, in 1980, of PIXEL, published by "Il Rostro", Milano, the first technical magazine on computer graphics in Italy.

I have published two introductory books on computer graphics and imaging (see references).
