- GREC'95: update

- Information: ICCV'95
- CFP: IEEE workshop on representations of visual scenes
- Information: VI'95

Dear IAPR TC10 friends,

The main information in this TC10 news is an update on the coming
GREC'95 event. We received 37 submissions (abstracts of proposed
contributions to the workshop). 5 submissions were rejected, mainly
due to the fact that their topic was out of the scope of the workshop,
and the other 32 were accepted. As announced, a further selection and
evaluation will be made by the program committee after the workshop
for preparation of a book with the best papers and probably some other
invited contributions... Letters have been sent out to all people who
submitted something, with information about the decision made. We
expect camer-redy papers by June 10th in order to have the
pre-proceedings ready for the workshop.

We have been working on a tentative program. As of today, it seems
that the workshop programme will be like this:

- Wed. Aug. 9 evening: welcome reception

- Thursday Aug. 10:

4 sessions
banquet with keynote speaker
dashed-line detection contest + informal discussion groups

- Friday Aug. 11:

working groups, discussions, recommendations
closing session
picnic !!

Each session would be organized like a panel on a given
topic. Accepted abstracts will thus be grouped by their topic. Each
session will have a panel leader who will make an extended
presentation describing the state-of-the-art and open research
problems. This will be followed by short presentations from other
panelists. Each session will conclude with discussions among the
panelists and the other attendees.

We repeat that we want in this way to guarantee a real working group
atmosphere, and not a formal conference atmosphere (ICDAR is just the
week after and more formal presentations belong there).

Practical details: financial support should make it possible to have
no registration fees or very modest fees. There is still room for
welcoming other attendees (without papers). Please write to
prof. Kasturi or to me if you are interested in attending... But be
quick, we don't have unlimited capacity.

We look forward to a very exciting and interesting workshop.

In direct relation with GREC'95, there will also be the contest on
dashed-lines detection. In order to organize the practical details of
this contest (how many machines to have at the workshop site, etc.),
we would like those who plan to take part in the contest to


but preferably as soon as possible, by sending an E-mail to me or to
prof. Kasturi (This email address is being protected from spambots. You need JavaScript enabled to view it. ).

3 prizes are foreseen for the dashed-lines detection winners!!!

More information on the contest has already been circulated in this
mailing list; if you want to get this info a second time or if you
missed it the first time, feel free to ask me for a copy....

Now to some other pieces of information.
First, information about the coming International Conference on
Computer Vision conference.

My apologies for inundating you with messages. However,
some people have had difficulties with retrieving the information referred
to earlier about ICCV. There is thus a new (compressed) version of the
post script file which hopefully will get around some of the
printing difficulties that a few sites experienced. This new version

The purpose of this workshop is to bring together researchers
interested in representation of visual scenes based on a
collection of images (either video or a collection of stills).
In recent years, two clear trends have emerged in the area of
multiple image analysis: image-to-image alignment based on
motion-field models, and recovery of 3D geometry in terms of
affine and projective invariants. Work in the first area has led
to techniques for panoramic view construction based on
multiple-image alignment and layered representations, whereas
work in the second area has lead to techniques for the
representation of scenes as collection of views and the recovery
of a new view as combinations of a set of given views.

Taken together, the new trends have led to new ways to formulate
the traditional problems of structure-from-motion and 3D scene
reconstruction. These emerging techniques are also closely
related to work in active/animate vision, especially to methods
that use fixation and tracking. Their benefits to visualization,
video databases, compression, and handling uncalibrated imaging
situations is already becoming apparent. However, one of the
major challenges, and a recent topic of lively interest, is to
obtain an adequate generalization of the fundamental structures
associated with two views to multiple-view situations. Such
generalizations are essential for understanding view-based
representations, visual database indexing, numerical stability of
3D recovery, and navigation. Several recent results suggest that
some of the accuracy and stability problems that have plagued the
previous generation of techniques can be overcome. Furthermore,
the issues of sparse versus dense scene representations, and
their usefulness for recognition, navigation and intelligent
video manipulation are areas of active research.

The workshop will be held on 24 June, the day after the end of ICCV95.
Hotel rates for ICCV95 have been extended. It will include 12-15
contributed presentations and a panel discussion at the end of the
day. Papers that are submitted will be reviewed by the program
committee. A proceedings will be made available a few months after
the workshop.

Prospective authors are invited to submit papers on topics described
above. Submissions should be 5-10 pages, including figures and
references. Send four copies of the paper summary and a cover sheet
stating the (1) paper title, (2) Brief 2-3 sentence summary of the
topic and contribution, (3) contact author's name, (4) address, (5)
telephone number, (6) Fax number, and (7) electronic mail address to:
