Subject: Toolbox of Level Set Methods

Version 1.0 of A Toolbox of Level Set Methods is now available at

This toolbox is a collection of routines for working with dynamic
implicit surfaces and approximating the solution of Hamilton-Jacobi
partial differential equations. Such problems arise in a variety of
fields including computational geometry, mesh generation,
differential games, dynamic programming, financial mathematics, fluid
and combustion simulation, graphics, image processing, computer
vision, robotics, control and verification.

The toolbox requires basic Matlab. The supplied routines work in any
number of dimensions on a fixed Cartesian grid. Upwind spatial
derivative and explicit temporal derivative approximations of high
order accuracy are included, as well as more than a dozen examples
drawn from the level set literature.

The toolbox is designed to ease the process of exploring level set
methods by minimizing the sum of coding, execution and analysis time.
While it is not by itself a tutorial on these methods, for those who
are new to the field it would serve as an excellent experimental
supplement to either of the textbooks listed below. Level set
practitioners may find it useful to generate independent solutions to
examples for comparison purposes.

Subject: Special Issue on Super-Resolution Imaging

EURASIP Journal on Applied Signal Processing Special Issue on
Super-Resolution Imaging: Analysis, Algorithms and Applications

Call for Papers

The recent increase in the wide use of digital imaging technologies in
consumer (e.g., digital video) and other markets (e.g., security and military)
has brought with it a simultaneous demand for higher-resolution images. The
demand for such high-resolution (HR) images can be met by algorithmic advances
in super-resolution (SR) technology in place ofXor in tandem with hardware
development. Such HR images not only give the viewer a more pleasing picture
but also offer additional details that are important for subsequent analysis
in many applications.

Because of the recent emergence of many key relevant computational,
mathematical, and statistical techniques, and the increasing importance of
digital imaging technology, a special issue of the EURASIP JASP dedicated
to the topic of SR imaging is quite timely.

A more detailed list of SR imaging topics of interest include
(but are not limited to):

Multiframe/multichannel direct and blind deconvolution in SR
Subpixel motion estimation
SR in time and dynamic range, etc
Artifact analysis of sensors and optics
Video-to-video SR imaging
Multiframe demosaicing and SR imaging
Wavelet-based methods for SR imaging
PDE-based methods for SR imaging
Locally adaptive image interpolation
SR in medical, astronomical, security/surveillance, and other applications

Authors should follow the EURASIP JASP manuscript format described at the
journal site Prospective authors should
submit an electronic copy of their complete manuscript through
the EURASIP JASP manuscript tracking
system at, according to the following

Manuscript Due December 1, 2004

Subject: Workshop in Portugal on Optimization in Finance

First Announcement
July 5-8, 2005
Coimbra, Portugal
Center for International Mathematics
School of Economics, University of Coimbra

Optimization models and methods play an increasingly important role
in financial decision making. Many problems in quantitative finance,
originating from asset allocation, risk management, derivative pricing,
and model fitting, are now routinely and efficiently solved using
modern optimization techniques. This workshop will bring together
researchers in the rapidly growing field of financial optimization
and intends to provide a forum for innovative models and methods
on new topics, novel approaches to well-known problems, success
stories, and computational studies in this exciting field. Participants
are encouraged to present and discuss their recent work and new,
possibly controversial, approaches are particularly welcome.

The targeted audience for this workshop includes graduate students
and faculty members working in applied mathematics, operations
research, and economics, who have been interested in mathematical
finance or plan to do so. The workshop will also be attractive
for those doing quantitative modeling in the financial market.

Invited speakers to the workshop include:

J. R. Birge (Northwestern University)
T. F. Coleman (Cornell University)
H. Konno (Chuo University, Japan)
J. M. Mulvey (Princeton University)
R. T. Rockafellar (University of Washington)
N. Touzi (CREST, France)
S. A. Zenios (University of Cyprus)

A one-day short-course, intended for optimization researchers
interested in quantitative finance as well as finance researchers
and practitioners interested in optimization models and methods,
will precede the scientific program of the workshop.
Short-course lectures will be delivered by Reha Tutuncu
(Robust Optimization in Finance) and Stanislav Uryasev
(Deviation versus Risk).

Invited and contributed presentations will be scheduled during the
remaining three days. Participants who wish to present a talk are
invited to submit a title and an abstract to by
April 1, 2005. Notification of acceptance will occur before May 1, 2005.
