Simply work with summing areas of triangles formed with
a) the coordinate origin
b) one of the edges in question.
For this to work, however, the curve must be closed cleanly, and plane.
Higher moments require the use of shift laws, such as Steiner's law.
This, of course, implies that you really mean the moments of the enclosed
area, not that of the boundary (as a wire model would have).

Subject: Color CCD camera
We want to buy a good qaulity CCD color camera, which should give us a
same level of intensity values at R, G, B bands. However we have not been
able to find it yet. Is anyone familiar with it? Your information
and help is highly appericated!
Pls reply to fang@cs.columbia.edu
Thanks in advance!

Subject: Request for cavity detection algorithm
Currently, I am doing a project of digit recognition and it requires
to detect the cavities and direction in a thinned handwritten
digit. I have already think of curve fitting algorithm but it seem
not to be work if I have a single line segment of digit 3 because I
have to detect it middle corner point first and cut it into two
halves. Moreover, I may have a digit 4 where its upper cavity is compose
of 3 straight (or near straight) line segment, like
/
/ |
/ |
/----------|
Another, special case is a single curve of six like:
/
/
/
/ ____
/ \
\ /
\-----/
Other special cases I can think of is something like opened loop(s) of
nine, eight. Because of handwritten digit, many variations of cavities may
appear. Does anyone have any idea to solve this ?
PS. Directions of cavity are East, South, West, North.

Subject: Off-line recognition of segmented handwritten numerals.
Hi, my problem consist of off-line recognition of handwritten numerals.
These numerals are written in drop-out color boxes (no segmentation
problem) and also the images are nicely binarized. The handwritten
is slightly constrained, which result in a less confusing numerals.
Does any body knows of any recent OCR product/paper which can attain
better than 1% substitution rate with say not more than 10% rejects?
I will be greatfull to receive any info. from you.
Thanks a lot,
Omid.

Subject: Looking for postdoc in vision
LOOKING FOR A POSTDOC IN VISION MODELING
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I am willing to submit a proposal in the context of the European
"Human Capital and Mobility" programme.
The idea is that the candidate comes here to work for 2 years under
my supervision, and then returns to his home country with a greater
chance of e.g. starting his own lab. Three years is also possible,
but than the last year MUST be spent in the home country.
CONDITIONS (AND QUITE STRICT):
1) Postdoc status (the application procedure may take half a year!)
2) Citizen of a European-Community country
3) From an "underdeveloped" area in that country
Entire countries: Greece, Ireland, Portugal. Other _EXAMPLES_:
GERMANY: Nordrhein-Westfalen, Bremen, Salzgitter/Peine,
Emden, Saarland, Rheinl-Pfaltz, Berlin, plus the old DDR Laender).
NETHERLANDS: Groningen/Drente, Twente, Limburg.
Great Britain: Northern Ireland, North-East, Eastern England,
West Midlands, North-West, West-Cumbria, Ciwyd, South Wales,
West and East Scotland.
When you are not sure or come from another country: first ask me
with a 3-line email message.
With respect to my specific project (the quantitative modeling of
brightness perception on the basis of complex Gabor filters):
4) Working knowledge of visual psychophysics
(spatial/temporal perception, brightness and contrast preferred)
5) Inclined to modeling
(quite heavy analytical analyses and computational simulations)
Eventually candidates with a very strong background in computer
vision and signal processing can apply. Also possible are candidates
with a background in retinal/cortical neurophysiology.
The latter, when interested in the modeling of cortical operators,
should contact me anyhow because I am thinking about submitting a
project on the modeling of neural operators for pattern recognition in
computer vision.
Programming: FORTRAN is a pro, C not per se, maybe some experience with
LATEX, MATHEMATICA, or MATLAB. UNIX of course.
The salary in Switzerland is about 4700 ECU gross/month
The Signal Processing Laboratory of the Swiss Federal Institute of Tech-
nology is well equipped with powerful workstations, quite some software
packages, and for the heavy jobs we have our CRAY-2 and Y-MP on campus.
There is not a real campus because we lack student lodging (all students
and up live in Lausanne and nearby villages). Lausanne is situated at what
is called the Swiss Riviera, with a view on the Geneva lake and the French
alps. See your nearby tourist office for more details. One important
detail: Lausanne is located in the French-speaking part of Switzerland.
The language in the lab is English because of the many nationalities, but
we advise taking French courses which are provided by the Institute.
I'll be in Italy next week for a conference (20-24 September).
Do _NOT_ send CV etc by email. Only if you're not sure about your chances
(home country etc) you can send me a 3-line email question.
Send your resume as soon as possible to:
Dr. J. du Buf
Signal Processing Laboratory
Swiss federal Institute of Technology
EPFL-Ecublens
CH-1015 Lausanne
Switzerland
dubuf@ltssun7.epfl.ch
If possible, provide an email address and/or fax number!

be submitted to any other conference during the CVPR review period.
Papers submitted to CVPR 94 are expected to describe original research results
which are being presented to the computer vision and pattern recognition
community for the first time. Submission of a paper to CVPR implies a
commitment on the part of the authors to produce the camera-ready proceedings
version of the paper and present the paper in person at the conference, if
the paper is accepted.
Through a cooperative arrangement with the European Conference on Computer
Vision, authors wishing to submit essentially the same paper to both CVPR
and ECCV may do so provided that they clearly state in their CVPR submission
letter that they are submitting to both and they indicate which conference
they will choose in case the paper is accepted for both.
The manuscript should include the following (in this order):
I. A Title Page -- Containing the names and addresses of the authors (including
e-mail), an abstract of up to 200 words, and one or more categories listed
above or other keywords that can be used to match submissions to reviewers.
II. A Second Title Page -- With just title and abstract (authors and institution
not identified).
III. A Summary Page -- Attach answers to the following questions (please answer
each separately):
(1) What is the original contribution of this work?
(2) Why should this contribution be considered important?
(3) What is the most closely related work by others
and how does this work differ?
(4) How can other researchers make use of the results of this work?
(4) If this work extends or relates closely to some other work you have
published, please state precisely how it differs from that work.
(5) If any part of this work has been submitted to other conferences or
workshops, please state where and how it is different.
IV. Paper -- No more than 30 pages (double-spaced, 12 point type) including
text, figures, references, etc.
As is customary with CVPR, reviewing will be double blind.
