neighbors. However in most practical situations, the
domain can be concave and there are communication
constraints related to the RF-transmission power. In this
talk, a historical overview of the area coverage algorithms
relying on Voronoi-partitioning and power diagrams will
be provided. Recent algorithms relying on the geodesicdistance based generalized Voronoi-diagrams under
communication constraints for area coverage will be shown
followed by illustrative simulation cases.
The technologies for creating digital 3D models of reality
have undergone an impressive evolution in the last years
and are mature enough to go beyond the plain visualization
of those assets.
Dr. Anthony Tzes is Professor and Head of the Electrical
& Computer Engineering Department of the University of
Patras (UPAT) in Greece. He is a graduate of UPAT (1985)
and received his M.Sc. and doctorate from Ohio State
University in 1987 and 1990, respectively. From 1990 until
1999 he was with Polytechnic Institute of New York
University.
Although developed for the entertainment and for industrial
purposes, these technologies are also ideal for helping the
knowledge, investigation, preservation and restoration of
cultural heritage (CH), devising new tools able to extend
our insight capabilities and to revise the current
consolidated procedures for CH research and management.
His research interests include Networked Controlled
Systems, MEMs, Robotics, Mechatronics, Adaptive
Control, Instrumentation and System Identification. Prof.
Tzes has received research funding from various
organizations including NASA, the National (U.S.) Science
Foundation, the European Union and the European Space
Agency.
In particular, technologies developed for digital sampling usually called 3D scanning - are useful for the creation of
quantitatively accurate digital 3D models of CH artifacts.
Beside visualization's potential, CH scholars and
practitioners perceive producing digital models and images
just as an intermediate goal without getting the full
potentialities of having this kind of data available. The
greater challenge lies in creating new tools that allow a full
exploitation of 3D models to assist CH research, helping to
assess conservation status or to plan and document
restoration.
He has been the Chairman of IEEE’s Control Systems
Society Greek Chapter, a member of the Greek committee
of the European Control Association, member at several
committees of the International Federation of Automatic
Control, and the national representative (2006-9) to EU’s
FP7’s thematic area “Regions of Knowledge, Research
Potential and Coherent Development of Policies”. He has
served in various positions (Organizing Committee
Chairman (ECC’07), General Chairman (MED2011)), and
as IPC-member at several international conferences. He has
served on the editorial board of several journals and he is a
Visiting Professor at U. of Loughborough, UK.
Dr. Paolo Cignoni is a Senior Research Scientist with
CNR-ISTI. He received a Ph.D. Degree in Computer
Science at the University of Pisa in 1998. He has been
awarded "Best Young Researcher" by the Eurographics
association in 2004. His research interests cover Computer
Graphics fields ranging from Level of Detail and out-ofcore techniques for visualization and processing of huge 3D
datasets, to 3D scanning data processing with a particular
focus to its use in the cultural heritage field and to
Scientific Visualization (molecular visualization and
isosurface extraction). He has taught the main 3D Graphics
course at the University of Pisa for more than 10 years. He
started and still leads the development of MeshLab, a
widely known open source mesh processing tool used by
thousands of users in hundreds of universities, research
centers and companies. He has published more than one
hundred papers in international refereed
journals/conferences and has served on the Program
committees of all the most important conferences on
Computer Graphics. He is on the Editorial Boards of IEEE
TVCG, The Visual Computer, and ACM Journal on
Computing and Cultural Heritage.
He has authored more than 250 papers published in

Location: Klio Room
in speech synthesis and speech modifications, speech
coding, speech enhancement, voice quality assessment, etc.
All these models, assume that speech, and audio in general,
is locally stationary during the estimation of their
parameters. Speech, however, is not stationary and
especially during fast transitions between phonemes and
voicing states it can be considered as highly non-stationary.
The same observations can be made for music signals and
other audio signals as well. To address the non-stationary
nature of audio signals, novel models have recently been
suggested where the audio signal is projected in a set of
non-parametric basis functions which are adaptive to the
local characteristics of the input signal. A central theme of
all the new and old speech and audio models is that of
frequency estimation.
Human centered video analysis tasks will be reviewed,
notably face detection, person tracking, facial pose
estimation, eye/mouth detection, visual speech detection,
dialog detection, human activity recognition, facial
biometrics, and facial expression recognition. XML
description schemes (MPEG7 profiles, notably AVDP) of
the analysis results will be presented.
3DTV content analysis tasks will be reviewed as well,
notably multiview face/person detection and tracking,
multiview video analysis, 3D face reconstruction. XML
description schemes (MPEG7 profiles) of the analysis
results will be presented.
In the suggested tutorial, I will address the frequency
estimation problem in the context of speech and audio
signal processing and more specifically I will focus on the
passage from the non-adaptive and stationary speech and
audio models to new adaptive and non-stationary
representations. Then, I will present applications and the
potential for using these new representations on the
analysis of speech making a focus on the analysis of
pathologic speech.
Ioannis Pitas, fellow IEEE, received the Diploma and PhD
degree in Electrical Engineering, both from the Aristotle
University of Thessaloniki, Greece. Since 1994, he has
been a Professor at the Department of Informatics of the
same University. He has served as a Visiting Research
Associate or Visiting Assistant Professor at several
Universities.
It is suggested that the tutorial is split into two parts. In the
first part of the tutorial, novel algorithms for the adaptive
audio analysis will be presented and how they are related to
the well known sinusoidal representation as well as to nonlinear frequency estimators like the Newton-Gauss. The
second part will be dedicated to applications like tremor
estimation, estimation of jitter and shimmer through a
mathematical – sinusoidal based – description, objective
evaluation of spasmodic dysphonia and vocal fatigue.
His current interests are in the areas of intelligent digital
media, image/video processing (2D/3D) and humancentered interfaces. He has published over 670 papers,
contributed in 39 books in his areas of interest and edited or
(co-)authored another 8 books. He has also been an invited
speaker and/or member of the program committee of many
scientific conferences and workshops. In the past he served
as Associate Editor or co-Editor of eight international
journals and General or Technical Chair of four
international conferences (including ICIP2001). He
participated in 63 R&D projects, primarily funded by the
European Union and is/was principal
investigator/researcher in 39 such projects. He has 13400+
citations to his work and H-index 56+.
Objectives
The main objective of this tutorial is to present to students,
researchers, and engineers working in the field of signal,
speech and audio processing, the recent developments in
sinusoidal models, in frequency estimation, in non-linear
speech and audio signal processing. In terms of
applications, to show how these novel algorithms of signal
processing can be applied in the domain of voice function
assessment and pathologic voices.

Modifying iDistance for a Fast CHAMELEON with
Application to Patch based Image Segmentation
Xiaochun Wang, Xia L. Wang (PR China), and
Don M. Wilkes (USA)
Complex Systems is a term that emerges in many
disciplines and domains and has many interpretations,
implications and problems associated with it. The specific
domain provides dominant features and characterise the
nature of problems to be considered. A major classification
of such systems are to those linked with physical processes
(physics, biology, genetics, ecosystems, social etc) and
those which are manmade (engineering, technology,
energy, transport, software, management and finance etc)
and deal with the “macro level” issues and technology.
Each of the above classes has its own key paradigms,
specific problems, concepts and methodologies. There exist
however generic common issues amongst the different
domains and this requires the need for developing generic
methodologies and tools that can be applied across the
different domains. For manmade systems, Systems and
Control concepts and tools are important in the
development of methodologies aiming for the Management
of Complexity.

Existing methods in Systems and Control deal
predominantly with fixed systems, where components,
interconnection topology, measurement-actuation schemes
and control structures are specified. Two new major
paradigms expressing forms of engineering complexity
which have recently emerged are the new paradigms of:

Retinopathy
Pilar Pérez Conde, Jorge de la Calleja,
Ma. Auxilio Medina, and Antonio Benitez (Mexico)
Using the traditional view of the meaning of the system
(components, interconnection topology, environment), the
common element between those two new paradigms is that
the interconnection topology may vary, evolve in the case
of SES, whereas in the case of SoS the interconnection rule
is generalised to a new notion of a “play” [1], [2]. The
paper deals with the fundamentals as far as representation,
structure, and properties of those two challenging classes,
demonstrates the significance of traditional systems and
control theory and introduces a new research agenda for the
required control theory for those two complex systems
paradigms. In fact:
10:30 – 11:00 COFFEE BREAK
Location: Lobby
Structure Evolving Systems [3]: Such a class of systems
emerge in natural processes such as Biology, Genetics,
Crystallography etc; the area of manmade processes
includes Engineering Design, Power Systems under deregulation, Integrated Design and Re-design of Engineering
9
Systems (Process Systems, Flexible Space Structures etc),
Systems Instrumentation, Design over the Life-Cycle of
processes, Control of Communication Networks, Supply
Chain Management, Business Process Re-engineering,
Data Processes etc. This family departs considerably from
the traditional assumption that the system is fixed and its
dominant features relate to:
exhibit features well beyond the standard notion of system
composition. They represent a synthesis of systems which
themselves have a degree of autonomy, but this
composition is subject to a central task and related rules
frequently defined as “system plays” expressing the
subjection of subsystems to a central task. This
generalisation of the interconnection topology notion
introduces special features and challenging problems,
which are different than those presented by the design of
traditional systems of the engineering domain. The
distinguishing feature of this new form of complexity is
[2]:
■The topology of interconnections is not fixed but may
vary through the life-cycle of the system (Variability of
Interconnection Topology Complexity).
■The overall system may evolve through the early-late
stages of the design process (Design Time Evolution).
■ There may be Variability and/or uncertainty on the
system’s environment during the lifecycle requiring
flexibility in organisation and operability (Lifecycle
Complexity).
■ The system may be large scale, multi-component and this
may impact on methodologies and computations (Large
Scale – Multi-component Complexity).
■ There may be variability in the Organisational Structures
of the information and decision making (control) in
response to changes in goals and operational requirements
(Organisational Complexity Variability).
• The role of “objects”, or “subsystems” of the traditional
system definition is taken by the notion of the autonomous
agent, which may be characterised by some form of
intelligence.
• The notion of “interconnection topology” of traditional
systems is generalised to that of “systems play”.
• Decision making and control may take the form of a game
amongst the subsystems.
In this setup emergence takes a new form. There is a
number of fundamental challenges, if the issue of design, or
re-design SoS is to be addressed and the shaping of a new
form of System of Systems Engineering methodology is to
be addressed.
The above features characterise a new paradigm in systems
theory and introduce major challenges for Control Theory
and Design and Systems Engineering. There are different
forms of structure evolution. Integrated System Design has
been an area that has motivated some of the early studies
on SES. The integration of traditional design stages [4],
such as Process Synthesis (PS), Global Instrumentation
(GS) and finally Control Design (CD) is an evolutionary
process as far model system formation and two typical
forms of evolution are the structural design evolution, the
early-late design evolution and the interconnection
topology evolution [3]. Methodologies and tools developed
for Fixed Structure Systems (FES) cannot meet the
challenges of the SES class and new developments on the
level of concepts, modelling, analysis and synthesis
methodologies are needed. The research is strongly
influenced by the need to address life-cycle and re-design
issues and such problems have a strong technological and
economic dimension.
Addressing the issues of SES and SoS has important
implications for the underpinning Control Theory and
related Design methodologies. Control Theory and Design
has developed considerably in the last forty years.
However, the underlying assumption has always been that
the system has been already designed and thus control has
been viewed as the final stage of the design process on a
system that has been formed. New paradigms have
emerged which enlarge the area where Control is relevant
and which challenge the “fixed system structure
assumption.” These force us to reconsider some of the
fundamentals (viewing Control as the final design stage on
a formed system) and create the need for new
developments where Control provides the concept and tools
intervening in the overall design process, even at stages
where the system is not fixed but may vary, may be under
some evolution. Traditional Control has been capable OF
dealing with uncertainty at the unit process level, but now
has to develop to a new stage where it has to handle issues
of structural, dynamic evolution of the system as well as
control in the context of a “systems play”. The paper
provides an overview of the two areas, deals with issues of
representation and introduces a research agenda for control
into this new setup.
System of Systems: The notion of “System of Systems”
(SoS) has emerged in many fields of applications from air
traffic control to constellations of satellites, integrated
operations of industrial systems in an extended enterprise to
future combat systems. Such systems introduce a new
systems paradigm with main characteristic the interaction
of many independent, autonomous systems, frequently of
large dimensions, which are brought together in order to
satisfy a global goal and under certain rules of engagement.
These complex multi-systems are very interdependent, but

His research has been in the development of the algebraic,
geometric and algebra-geometric methods for Control
Theory. His research on the Control fundamentals has been
accompanied by an effort to migrate Systems and Control
to Complex problems, such as the development of a
Control based methodology to Systems Integration and
developing Control based methodology for Complex
Systems. This research has been supported by EPSRC and
a number of EU projects. He has been the author/co-author
of over 230 scientific publications, the holder of a number
of research grants including eight major EU grants and
supervisor of over twenty completed PhD theses. His
research publications are in the areas of Linear Systems,
Mathematical Systems Theory, Control Theory and Design,
Algebraic Computations, Mathematical Methods for
Control, Systems Theory of Measurement, Systems and
Control to Complex Systems, Integrated Systems Design,
and History of Systems and Control. The main drive of his
current research is the development of systems and control
for complex systems, by developing the theory required for
the new systems paradigms of “structure evolving systems”
and “Systems of Systems”.
