On getting no responses with the info that I had asked for, I
searched harder on my desk and located the brochure. It only
contains the snail mail address of the contact person:
R.M. Rodrigues, L-153

Subject: Visual System Characteristics
Date: Wed, 15 Mar 89 15:45:45 EST
I am interested in collecting visual system characteristics from as
many different species (both vertebrates and invertebrates) as possible.
In particular, I would like to know for each type of animal:
- the approximate number of cortical (and/or sub-cortical) neurons
devoted primarily to vision
- whether or not `visual maps' have been discovered, and if so,
how many, what is their size (in neurons), how are they organized,
and any other known characteristics. Positive statements about the
absence of maps are also important.
- average cortical fan-in and fan-out for visual neurons in terms of
other neurons rather than total synapses
Please cite references as well.
Both physical and electronic mail addresses are given below.
I will gladly summarize and post the results on the net
if there is enough interest.

Subject: Lectureship or Assistant Lectureship
University of Cambridge, UK
Department of Experimental Psychology
LECTURESHIP or ASSISTANT LECTURESHIP in Psychology
An appointment of a Lecturer or Assistant Lecturer in Experimental
Psychology will be made shortly under the New Academic Appointments
Scheme, subject to funding from the University Grants Committee. The
starting date will be October 1, 1989, or as soon afterwards as possible.
The appointment will be made in the general area of cognitive psychology,
cognitive neuroscience or developmental psychology; preference may be
given to candidates working on computational modelling of cognitive
processes or on associative or neural networks.
The salary for a University Assistant Lecturer is UKL 10,460 p.a. rising
by four annual increments to UKL 12,760, and for a University Lecturer,
UKL 13,365 p.a., rising by eleven annual increments to UKL 20,615.
All Assistant Lecturers are consider for upgrading to Lecturer during
their appointment.
Further formal particulars may be obtained from Dr. D. Franks, Secretary
to the Appointments Committee for the Faculty of Biology B, 19 Trumpington
St., Cambridge CB2 1QA, to whom applications should be sent by 17 April, 1989.
Informal enquiries may be directed to Professor N. J. Mackintosh (223-333551)
Department of Experimental Psychology, Downing St., Cambridge, CB2 3EB,
United Kingdom; or, if urgent, to jm123@uk.ac.cam.phx.

Subject: Re: Call for image processing software
The following is in response to your request for infor-
mation on image processing software.
HIPS is a software package for image processing that
runs under the UNIX operating system. HIPS is modular and
flexible, it provides automatic documentation of its
actions, and is almost entirely independent of special
equipment. It handles sequences of images (movies) in pre-
cisely the same manner as single frames. Programs have been
developed for simple image transformations, filtering, con-
volution, Fourier and other transform processing, edge
detection and line drawing manipulation, digital image
compression and transmission methods, noise generation,
image pyramids, and image statistics computation. Over 150
such image transformation programs have been developed. As
a result, almost any image processing task can be performed
quickly and conveniently. Additionally, HIPS allows users
to easily integrate their own custom routines.
HIPS features images that are self-documenting. Each
image stored in the system contains a history of the
transformations that have been applied to that image. HIPS
includes a small set of subroutines which primarily deals
with a standardized image sequence header, and a large
library of image transformation tools in the form of UNIX
``filters'' written in `C'. As a result it runs on any Unix
workstation (users run it on equipment from Sun,
Vax/Microvax, Masscomp, NCR, Silicon Graphics/Iris, Apollo,
etc. etc.). HIPS has proven itself a highly flexible sys-
tem, both as an interactive research tool, and for more
production-oriented tasks. It is both easy to use, and
quickly adapted and extended to new uses.
HIPS is distributed by SharpImage Software, P.O. Box
373, Prince Street Station, New York, NY 10012-0007. To
obtain more information, write us or call Michael Landy,
(212) 998-7857 (landy@nyu.nyu.edu). HIPS consists of a
basic system and a number of additional modules (for fancier
Sun display, additional image tools, etc.). The basic sys-
tem costs $3,000, and is available at a considerable
discount to qualified educational, non-profit, and US
government users. The base price is for all computing
equipment within a particular academic department of commer-
cial laboratory. The software comes complete with source,
libraries, a library of convolution masks, documentation,
and manual pages. It also includes drivers for the Grinnell
and Adage image processors, display drivers for the Sun
Microsystems consoles under SunView, gfx, and straight to
the console. Users have contributed drivers for the Matrox
VIP-1024, ITI IP-512, Macintosh II, X windowing system,
Iris, and Lexidata. It is a simple matter to interface HIPS
with other framestores, and we can put interested users in
touch with users who have interfaced HIPS with the Arlunya,
and Datacube Max-Video. Our Hipsaddon product includes an
interface to the CRS-4000. HIPS can be easily adapted for
other image display devices because 98% of HIPS is machine
independent. It has been described in Computer Vision,
Graphics, and Image Processing (Vol. 25, 1984, pp. 331-
347), and in Behavior Research Methods, Instrumentation, and
Computers (Vol. 16, 1984, pp. 199-216).
