Status: RO
Al Zobrist used a vision-correlational approach to [the game of] GO in
his Ph.D. thesis here (see diss abstracts). He published this in one
of the Joint Computer Conferences (Eastern or Spring, around 1968-72).

Subject: Summary of Image Processing Languages
Keywords: image vision language
Organization: MacDonald Dettwiler, Richmond, B.C., Canada
A couple of weeks ago I asked the net for pointers to image processing
lanaguages (not libraries). I was looking for a computer programming
language that would allow me to inter-image operations. That is,
operations such as feature identifcation.
It seems that such things don't really exist. All commercial packages
that claimed "language" were really function libraries (choose your
favorite language) with a little bit of control structure thrown in (a
bonus ?). These libraries perform image to image transformations.
They give you like access to the internals an image.
Some systems were all control structure (KBVision as an example).
These systems provided good end user environments, but not good for
programmers or analyst tring to develop new image processing systems.
(KBVision is great!, get it if you need an image processing system for
"image" engineers, but its not really for programmers.)
Further, most products were tied to specialized hardware. I work in
the research department and have to live with stock SUN 3/60s. So even
as libraries, most of these products are useless to us.
I did receive three informed responces to my query. One person
suggested a set of unix filters (that he wrote) as a useful image
processing language. Another suggested IDL (image description
langauge ?). The third forwarded seven good references on the
subject. I am researching them now. Maybe, I'll write that image
processing language myself.
=====included================
I am not familiar with any image languages, per se, although in the
past I've seen some references to them in the literature. I have
written a general image processing software package (your image->image
transformations, mostly) which consists of a large number of UNIX
`filters' which can be connected up in relatively arbitrary ways using
the UNIX `pipe' facility. If that sounds useful, let me know, and
I'll mail you some blurbs.

[Reply to Randy's original request for vision language information. pk...]
Subject: Re: Vision/Image Processing Languages We developed an
image-to-image language at Leeds on the transputer array, called
APPLY, which was originally from CMU fro the Warp machine. APPLY
performs localised window operations, eg. edge detection, 2D
convolution. The APPLY compiler generates OCCAM (for transputer
arrays), C (for UNIX machine) and W2 (for Warp) at the moment,
although it is aimed at machine independent. This language has two
major advantages: (1) ease the programming efforts, (2) efficiency.
For instance, it does better on the Canny edge detector than the
hand-crafted code reported in the literature.
If you are interesting, pls contact me. I could not reach you by e-mail.

Subject: e-mail addresses for range data
hi, in recent vision lists there has been correspondence about range
image data bases. I wish to obtain further information about these
databases by email. However no email addresses have been given in the
vision list. Anyone know the email address for
M Rioux or L Cournoyer
National Research Centre of Canada
Ottawa, Ontario. Canada
or
Tom Henderson
University of Utah
many thanks John Illingworth
