contains the snail mail address of the contact person:

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.

      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)

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).
