Subject: Decision on Fisher Price Camcorder
Organization: EECG, University of Toronto
So far I've gotten about 10-13 requests for what I've
found out about the Kiddie Camcorder. So I'll type it in
(it's going to be part of my thesis) and send it to vision
list. Expected date of arrival: March 6. This week and next
week are way too busy. Iron ring capers, ceremonies, et al.
cheers

Subject: Paint algorithm needed
A friend of mine is working on an object recognition project for
his senior project. He was using some terribly inefficient algorithm to
find the area, centroid, corners, etc., of an object. This algorithm was
taking 11 seconds (a uVAX using C)! I suggested a quick paint/fill
algorithm with some modifications as a better way to obtain these
statistics.
I'm looking for an efficient algorithm that will fill a solid object or
an outlined object (similar to how graphics editors do the "paint-can"
effect). Can anyone give me some pseudo-code or point me to an appropriate
reference guide?

The following report is available. Simply send an e-mail message to one of the
two authors, with your postal mail address. NB: Part I was distributed last
summer.
The Algebraic Basis of Mathematical Morphology; Part II: Openings and Closings

ABSTRACT: This paper is the sequel to a previous paper (Part I) where we have
introduced and investigated an abstract algebraic framework for mathematical
morphology. The main assumption is that the object space is a complete
lattice. Of interest are all (increasing) operators which are invariant under
a given abelian group of automorphisms on the lattice. In Part I we have been
mainly concerned with the basic operations dilation and erosion. In this paper
we will concentrate on openings and closings, which are very special classes
of idempotent operators. Much attention is given to specific methods for
building openings and closings. Some examples illustrate the abstract theory.

Subject: Conf. on VISION & 3-D REPRESENTATION
Conference on
VISION AND THREE-DIMENSIONAL REPRESENTATION
May 24-26, 1989
University of Minnesota
Minneapolis, Minnesota
The appearance of the three dimensional world from images pro-
jected on our two dimensional retinas is immediate, effortless,
and compelling. Despite the vigor of research in vision over the
past two decades, questions remain about the nature of three di-
mensional representations and the use of those representations
for recognition and action. What information is gathered? How is
it integrated and structured? How is the information used in
higher level perceptual tasks? This conference will bring togeth-
er nineteen prominent scientists to address these questions from
neurophysiological, psychological, and computational perspec-
tives.
The conference is sponsored by the Air Force Office of Scientific
Research and the University of Minnesota College of Liberal Arts
in cooperation with the Departments of Psychology, Computer
Science, Electrical Engineering, Child Development, and the
Center for Research in Learning, Perception, and Cognition.
Registration:
-------------
The conference fee is $30 ($15 for current students). This fee
includes program materials, refreshments, and Wednesday's recep-
tion. Conference enrollment is limited, so early registration is
recommended.

Subject: Re: X11R3 on Mac?
Summary: X11R3 for A/UX is Apple product
Organization: Apple Computer Inc, Cupertino, CA
Apple will ship its X11R3 product for A/UX in March (1989). The
server will support 1-bit and 8-bit deep frame buffers, multiple
screens, backing store and save unders. The graphics code has
undergone substantial optimization. X11R3 will run on both A/UX 1.0
and A/UX 1.1, however A/UX 1.0 allows just a single monochrome screen.
Apple has contributed sources for a single screen, monochrome server
to the MIT X Consortium. These appear on the X11R3 distribution which
has been publicly available since October. comp.windows.x regularly announces
ftp (and other) sites where this distribution may be obtained.
