Stefano Tubaro was born in Novara in 1957. He
completed his studies in Electronic Engineering at the "Politecnico di
Milano", Italy, in 1982. He then joined the Dipartimento
di Elettronica e Informazione
of the "Politecnico di Milano", first as a
researcher of the National Research Council, and then (in November 1991) as an
Associate Professor. Since December 2004 he has been appointed as Full
Professor of Telecommunication at the Dipartimento
di Elettronica e Informazione
of the "Politecnico di Milano", where he
became the Coordinator of the Telecommunications Section of the "Dipartimento di Elettronica e Informazione" in 2008.
His current research interests are on image and
video analysis for the geometric and radiometric modeling of 3D scenes; advanced
algorithms for video coding and sound processing.
Stefano Tubaro authored over 150 scientific
publications on international journals and congresses. He also co-authored two
books on digital processing of video sequences. His main research contributions
were, initially, on the use of differential motion-compensated schemes for
frame interpolation (upsampling along time) of video
sequences; and in the use of vector quantization in motion-compensated video
coding schemes. He then used the acquired expertise on motion analysis between
images to the case of 3D reconstruction from multiple views. In particular, he
developed effective techniques for disparity map estimation and for the use
image triplets to resolve ambiguities in depth estimation; methodologies for
camera self-calibration and egomotion estimation;
innovative methods for 3D surface reconstruction based on the fusion of depth
maps or on levelset evolution. In the area of video
coding, he participated and contributed to the activities of the ISO-IEC MPEG
working group for the definition of the MPEG4-SVC (Scalable Video Coding)
Standard; he then worked on the use of the distributed source coding approach
for defining new video coding approaches where the computational complexity is
moved from the coding side to the decoding side. This approach proved essential
to the development of light video acquisition/delivery systems, such as video
sensor networks.
In the past few years he has focused on the
development of innovative techniques for image and video tampering detection
and, in general, for the blind recovery of the processing history of multimedia
objects.
As far as
audio processing is concerned he worked on innovative methodologies for sound
synthesis based on physical modeling. He also worked on solutions for music
information retrieval, with particular emphasis on content-based musical genre
classification. With similar approaches he also worked on sound classification
for applications of safety and security. Another area of focus in the audio
realm has been space-time audio processing for both sensing and rendering
applications. He developed solutions for acoustic source localization and
tracking, for advanced beamforming, and for the sound-based extraction of
information on the environment (geometry and reflectivity of walls). As for
acoustic modeling is concerned, he worked on innovative methods for fast
modeling of acoustic propagation in complex environments, based on path tracing
and beam tracing in the ray space. As far as audio rendering is concerned, he
worked on Environment-Aware Geometric WaveField
Synthesis based on arrays of speaker, developing solutions for geometric room
compensation and virtual environment rendering.
Stefano
Tubaro coordinates the research activities of the Image and Sound Processing
Group (ISPG) at the "Dipartimento di Elettronica e Informazione"
of the "Politecnico di Milano". The group
includes a Full Professor (Stefano Tubaro), an Associate Professor (Augusto
Sarti), two Assistant Professors (Marco Marcon, Marco Tagliasacchi), and a
total of eight researchers (post-docs, phd students,
research assistants). The ISPG group manages two laboratories (about 700 sqm in
total) one in Milano (ISPG-Multimedia Lab) and one in Como (ISPG-Sound and
Music Computing Lab).
ISPG
contributed to numerous national and European Research Projects:
In the following a partial list of the European projects to which ISPG
has participated:

In
particular, it is important to mention that Stefano Tubaro has been the role of
Project Coordinator of the ICT-2000-28436 European Project "ORIGAMI: A new
paradigm for high-quality mixing of real and virtual". He was in the
management board of the Network of Excellence funded by the European
Commission: ICT-NOE-VISNET-I/II (Networked audiovisual media technologies).
From May 2011 he is the Coordinator of the research project ICT-FET-OPEN REWIND
REVerse engineering of audio-VIsual
coNtent Data (www.rewindproject.eu).
This project is aimed at synergistically combining principles of signal
processing, machine learning and information theory to answer relevant
questions on the past history of such objects.
Stefano
Tubaro has also been the scientific responsibly of several research and
development contracts signed by ISPG with national and international companies.
Moreover Stefano Tubaro is (and has been) involved in many evaluation and
concertation activities for European Projects. He has also be
part of the IEEE Multimedia Signal Processing Technical Committee (2005-2009),
and from January 2012 he has been elected as member of the IEEE SPS Image Video
and Multidimensional Signal Processing Technical Committee. Stefano Tubaro has
been guest editor of several special issues published by EURASIP journals; he
also has been among the organizers of a number of international conferences:
IEEE-MMSP-2004/2013, IEEE-ICIP-2005, IEEE-AVSS-2005/2009, IEEE-ICDSC-2009 to
mention a few.
From May
2012 he is an Associate Editor of the IEEE Transactions on Image Processing.
