was born in Tesero, Trento (Italy) in 1959. She received her degree in Electronic Engineering from the University of Padova, ITALY, in 1987. Ensuing her graduation she worked on radar electronics for fighters jets before joining the VLSI research group at IRST in 1989. Since 1990 she is an active member of the Computer Vision Group.
COMputer Aided Search System
R. Brunelli and O. Mich
COMPASS is a distributed application for content-based image retrieval
using remote databases. The system is configured as a client-server
architecture in which a client application can submit a user query to
multiple image servers.
Statistical methods are used to quantify image descriptor
effectiveness, to simplify user queries and to select an image
comparison strategy which optimizes search speed while preserving
The COMPASS system can be used for two main activities: to browse
still image databases, and to search image databases for pictures
similar to a set of photos or drawings provided by the user.
The COMPASS system has been developed in the context of the Esprit
Project No. 25389: OPAL.
VIDEO: Video and Image Data Exploration and Organization
R. Brunelli and O. Mich
The future of digital telecommunications is strictly linked to systems
which are able to manage multimedia databases providing type specific
interfaces. The purpose of the VIDEO (Video and Image Data
Exploration and Organization) system, developed at ITC-IRST is to provide
a leading edge tool to cope with image and video data in type and
application specific ways.
A set of algorithms to partition a video stream into shots has been
The algorithms are able to detect abrupt changes of scenes (cuts) and
gradual transitions (edits) as well. Camera operations are also
estimated and provide additional information useful in characterizing
video structure. The resulting shots are then described at different
level of detail by appropriately chosen key-frames.
Building on the functionalities of the developed algorithms an
interactive graphical interface has also been developed whose features
are: compact layout to optimize video stream presentation by
representative key-frames (linear and lighttable visualization);
multiple detail levels for the key-frame representation; simultaneous
multiple video streams presentation; possibility of simultaneous
multiple shots playing with VCR-like functionalities; shot annotation
capabilities; detection of similar shots (e.g. to speed-up the
Significant applications of the resulting system are: support for
video annotation; video abstracting for Video on Demand systems; video
