Signals & Images Laboratory

Set up in 2002, the Signals & Images Lab (SI-Lab) is an inter-disciplinary research laboratory in computer vision, signal analysis, smart vision systems and multimedia data understanding.
Researchers and technologists in computer science, mathematics, engineering and physics work together to produce original and effective research in computer vision and signal analysis, and to transfer knowledge and innovative solutions to society and industrial production and services, from cultural heritage to tourism, from mobility to entertainment, from security to environment, as well as healthcare and wellness.


To foster innovation by considering that sensorial information is increasing its importance in both our daily life and the most advanced technological and scientific contexts.
To boost the understanding of visual and audio information which is becoming the most significant part of the global data to be processed, understood and manipulated.


To increase knowledge in the fields of signal processing, image understanding and artificial vision, in both theoretical and applicative contexts.
To study and develop models, computer-based methods and machines for the formation, elaboration, analysis and recognition of images and signals, and to apply these methods and techniques to several sectors of the public and private society having strategic, scientific and technological interests.


To pursue front-line, reality-driven basic and applied research in emerging fields of computer vision and signal analysis relevant to the actual and future needs of the Internet society and industry.
To improve the research quality in relevant areas of signals and images in order to continue participating in high-level research partnerships and attracting Industrial, Regional, National and European funding.
To make high-level education and training for university students and doctoral schools.
To transfer innovative knowledge and technology to the various facets of the society.


In September 2000, the Institute of Information Processing (IEI-CNR) and the CNUCE Institute (CNUCE-CNR) of the Italian National Research Council in Pisa merged to form the Institute of Information Science and Technologies (ISTI-CNR).
Following this fusion, the former internal bodies of the two institutes were reorganized to give rise the present scientific structure of ISTI.

In particular, the beginnings of IEI-CNR can be traced back to 1954 when Pisa University, on the advice of the Nobel laureate Enrico Fermi and financially backed by the provinces of Pisa, Lucca and Livorno decided to design and construct a computer intended entirely for scientific use, the first in Italy. The Center for Studies on Electronic Computing (CSCE) was thus founded, and in 1961 the Pisan Electronic Computer - CEP - was inaugurated.
In 1962 the CSCE became part of the CNR, and in 1968 was renamed Istituto di Elaborazione dell'Informazione (IEI).

By statute, IEI-CNR was organized into five research Departments (Languages and Operating Systems, Architecture of Computer Systems, Techniques for Information Processing, Computational Mathematics and Computer Graphics, Signals and Images Processing) and some supporting technological Services, among which the Image Processing Service.

At the time of ISTI-CNR establishment it was then constituted the Signals and Images Laboratory (SI-Lab), as a result of the unification of the whole Department of Signals and Images Processing and the Image Processing Service. Soon after, the SI-Lab incorporated two other research groups of CNUCE-CNR, the Computer Art and the Creative Virtual Systems groups.

Virtualità intErattiva nel paRco di pinOcchio

Funded under: POR FSE 2014 -2020

Start date 1 June 2020    End date 31 May 2022


Keywords: Augmented reality; Cultural heritage; Interaction design

ICT technologies can foster understanding and fruition of cultural heritage supporting and enriching of the visitors experience. In particular, augmented reality (AR) systems can encourage greater and wider involvement of the public. Moreover, they can be useful for overcoming cognitive barriers, for a more inclusive access. In this project we will create a special AR based app for the Pinocchio Park, located in Collodi (Tuscany). The mosaics in the Piazzetta di Venturino Venturi, inside the Park, will be animated with original 3D contents, thanks to AR technologies. The visitors, by framing the scenes of the mosaics (depicting book episodes) with the device, will be able to view 3D animations perfectly integrated with the real scene, giving the illusion that the mosaic comes alive in the space. The AR app will be available both on dedicated wearable viewers (delivered by the staff at the entrance of the park) and via smartphone app, freely downloadable. The 3D animated contents will be carried out by digital artists, collaborators of Alma Artis Academy in Pisa, under the artistic supervision of the Collodi Foundation.
