II.  The new SIAM Journal on Imaging Science 
III. Coming Up: SIAM Conference on Imaging Science
IV.  Call for Opportunities Available or Wanted

Greetings!  This is the first SIAG/IS newsletter in two years, the
previous being four years before that.  I hope to do better than a
geometric sequence of ratio 1/2, though not for very long.

This is also the first Newsletter to be sent to the new SIAG/IS
moderated e-mail list, siam-imaging@siam.org.  I am hoping that this
list will foster greater communication among the SIAG membership, and
make the Newsletter a better vehicle for information.  Also serving
this need will be the new SIAG/IS website,
http://siags.siam.org/siagis/ For the moment, it is almost
identical to the old website, which we can thank Jackie Shen for
setting up.  One way to thank him would be to buy his book with Tony
Chan:

I. Welcome from your new SIAG/IS Officers

In February, the results of the election for the Activity
Group on Imaging Science were announced.  Your new officers are:

Luminita Vese, Chair 
Jennifer Mueller, Vice Chair 
Stacey Levine, Program Director 
Rick Chartrand, Secretary 

Our terms began January 1, making the first month of our terms as
mistake-free as any in the history of elected office.  We would like
to thank the SIAG/IS membership for your support.  Feel free to
contact us with issues or suggestions.  (Contact information available
via http://siags.siam.org/siagis/welcome.html.) 


II. The new SIAM Journal on Imaging Sciences

The long-awaited SIIMS published its first issue last month.  The
Editor-in-Chief is Guillermo Sapiro, whose journal-opening remarks are
included below.  The journal is available online for free for 2008;
see http://siam.org/journals/siims.php .  The following are the papers
with the honor of comprising the first issue:

"Efficient Reconstruction of Piecewise Constant Images Using Nonsmooth
Nonconvex Minimization," Mila Nikolova, Michael K. Ng, Shuqin Zhang,
and Wai-Ki Ching.

"Topology Preserving Linear Filtering Applied to Medical Imaging,"
A. Buades, A. Chien, J. M. Morel, and S. Osher. 

"Cascadic Multiresolution Methods for Image Deblurring," Serena
Morigi, Lothar Reichel, Fiorella Sgallari, and Andriy Shyshkov. 

"Edge Illumination and Imaging of Extended Reflectors," Liliana
Borcea, George Papanicolaou, and Fernando Guevara Vasquez. 

"Segmentation under Occlusions Using Selective Shape Prior," Sheshadri
R. Thiruvenkadam, Tony F. Chan, and Byung-Woo Hong. 

"Bregman Iterative Algorithms for $\ell_1$-Minimization with
Applications to Compressed Sensing," Wotao Yin, Stanley Osher, Donald
Goldfarb, and Jerome Darbon. 

And since he can mark the occasion better than I can, here's
Guillermo's message from the first issue:

Dear SIIMS Reader, 

It is a great pleasure and privilege to welcome you to the first issue
of the SIAM Journal on Imaging Sciences. This journal, with the help
of its editorial board, contributors, readers, and SIAM staff, follows
the outstanding tradition of high-quality SIAM journals and will
become a leading journal in the broad aspects of fundamental imaging
sciences. 

The journal began accepting submissions in April of 2007. By the end
of February 2008, SIIMS had received 88 manuscripts submitted for
publication. Of these, you will find the first six accepted papers in
this first all-electronic issue. Additional papers have been accepted
recently and will appear in subsequent issues. The papers in this
issue provide a representative glance of the diversity of topics
covered by the journal, something clearly observable from the
outstanding editorial board itself. A number of papers currently in
the pipeline and to be published in future issues further stress the
broad vision of the journal. 

SIIMS came to light thanks to the tremendous effort of numerous
people, and I want to publicly thank them. Prof. Tony Chan worked very
hard with SIAM to define this new journal. The whole SIAM staff is
superb, and without them my life as editor-in-chief would be
impossible. In particular, Mitch Chernoff and Cherie Trebisky have
been a critical source of support. The current editorial board has
been very supportive and worked very hard to guarantee timely and
high-quality reviews. The whole cycle of reviewing and production has
been extraordinarily fast on average; some of the papers in this issue
were submitted just a few short months ago, and some in this issue
were accepted less than two months ago. I appreciate very much the
support of all the people involved with this journal and their hard
work in making this possible. 

Please enjoy your reading, and we look forward to your high-quality
submissions in the future. 

Sincerely,
Guillermo Sapiro
Editor-in-Chief

website, http://siags.siam.org/siagis.  For example, another new
journal is Inverse Problems and Imaging, by the American Institute of
Mathematical Sciences: http://www.aimsciences.org/journals/ipi/ipi_online.jsp


III. Coming Up: SIAM Conference on Imaging Science

The next biennial SIAM Conference on Imaging Science will be July 7-9,
in San Diego at the Town and Country.  The program is now available
at the conference website: http://www.siam.org/meetings/is08/
Register and book your room soon, or face being on the wrong side of
I-8.  (Paste 500 Hotel Cir N, San Diego, CA 92108 into Google Maps to
get a sense of the area.  Note the metro station and mall to the north
of the hotel site.)

The conference is being held in conjunction with the first part of the
SIAM Annual Meeting.  Its program is now available:
https://www.siam.org/meetings/an08/program.php 

Let me call your attention to the SIAG/IS Business Meeting, July 7,
6:45 - 7:15, shortened for 2008.  (Don't blink.)  You can bring your
ideas about how to make this a better 
SIAG, where to hold the next IS conference, even who should replace us
as officers.  (I know we just started, but all good things must come
to an end.)

If the San Diego sunshine appeals, the IEEE International Conference
on Image Processing will be there October 12-15.  If you haven't
looked into IEEE events before, check out the program when it comes
available in a month or two (http://www.icip08.org).  A lot of good AM
gets done in EE, probably more than vice versa.

Other conferences can be found on the SIAG/IS website, 
http://siags.siam.org/siagis.

IV. Call for Opportunities Available or Wanted

Want to hire an Imaging Scientist (whatever that means to you)?
Looking for students for your Imaging REU?  Are you an Imaging
Scientist, looking for that special somejob?  I would like to
disseminate both Opportunities Available or Opportunities Wanted to
the SIAG membership and beyond.  Detailed postings will go on the
website, with shorter versions with links to be sent out periodically,
depending on response.  I may set up a web form for this, but for now,
send details to me at rickc@lanl.gov.  Be sure to include a deadline
or expiry date.

That's all from me, for now.

Rick Chartrand
SIAG/IS Secretary
