Subject: NIST Image Recognition Group anonymous ftp site

   The Image Recognition Group at NIST (National Institute of
Standards and Technology) is proud to announce the openning of an
anonymous ftp site.  This site contains loads of valuable information.
For example a database of hand written characters, descriptions of CD
databases available from NIST, many reports and papers published by
the group are available.

Sitename: sequoyah.ncsl.nist.gov
Internet number: 129.6.61.25
FTP Login name: anonymous
FTP Login password: {your username}@{your machine name}
   The above is also known as you e-mail address :-)

   Here are some simple instruction on how to get items from the site.
An actual ftp section is shown with my instruction to you indented.
The other lines are what happenned on the screen during the section.

your_prompt> ftp sequoyah.ncsl.nist.gov
Connected to sequoyah.ncsl.nist.gov.

ftp> binary
   You type "binary".  This sets the transfer in non-ASCII mode.
   If you do not do this the files may get corrupted!

   You type "prompt".  This turns off the interactive mode.  You can now get
   multiple files without being prompted.
Interactive mode off.

   From here you need to "cd" to the directory which contains the
files you want then use "get" any one file or "mget" multiple files.
"mget *" will get all the files in the directory.  When you are done
"quit" will exit ftp.

   This is a rough explanation of using ftp.  Please consult your
system administrator on how to use ftp if you don't know how.  If you
have any problems with the NIST site let me know.  I will do all I can
to help.

   This is a growing site.  Periodically new publication and data will
be posted here.  Stop by and check it for new items if we are working
on things you are interested in.

Subject: facial scanning

	Could anyone point me in the right direction for this problem. I am 
working on a fractal video compression system, which is aided by interframe 
differencing. The image is divided up into a grid of squares, 22x18 of them. To
aid the efficient transmission of blocks I need a priority queuing scheme.

	One system of priority checking I have decided to use is a block
coordinate based system. That is, the mouth and eyes have most priority, as
this system is to be used as a video-phone. So what I am after is reports,
theses, papers etc on how the average, if there is such, person scans another
face when in conversation. Such things as what order and with what frequency
are needed.

Any help will be greatly appreciated.
Could all replies be emailed to jez@ee.bath.ac.uk or J.A.Nicholls@bath.ac.uk
as I don't get that much time to read usenet.

Subject: SharpImage Software Releases Public Domain HIPS Software

A public-domain package is now available for reading and writing images
in a format compatible with the HIPS software for image processing.
This package includes routines for reading and writing the standard
image header which precedes every image in HIPS format (both in the
original HIPS-1 format, and in the format written by HIPS-2 programs in
the 2nd release of HIPS of Fall 1991).  The intent of this package is
to make it possible for programmers who are not HIPS users to be able
to read and write HIPS files and to write programs (such as image
format conversion programs) which are not dependent upon ownership of a
HIPS license.

To acquire the public domain HIPS header routines via anonymous ftp:
	ftp desdemona.cns.nyu.edu	****or****	ftp 128.122.154.48
	Name (desdemona.cns.nyu.edu:yourname): anonymous
	331 Guest login ok, send ident as password.
	Password:<type your email address as the password>
	ftp> cd pub
	ftp> binary
	ftp> get hipspub.Z
	ftp> quit

	uncompress hipspub
	tar xvf hipspub

This creates a directory called `pub' in your current directory.  Then,
read the files pub/README and pub/README_INSTALL for further instructions.

HIPS itself is a general package for image processing which runs under
the UNIX operating system.  It handles sequences of images (movies) in
precisely the same manner as single frames.  Programs have been
developed for simple image transformations, filtering, convolution,
Fourier and other transform processing, edge detection and line drawing
manipulation, pattern recognition, digital image compression and
transmission methods, noise generation, and image statistics
computation.  Over 200 such image transformation programs have been
developed.

Subject: Lectureship in Computer Science

UNIVERSITY OF BRISTOL
Department of Computer Science


Applications are invited for a Lectureship in Computer Science now tenable.

FURTHER PARTICULARS

The Department is part of the Faculty of Engineering.  It has a complement of
eighteen full-time UFC-funded staff members, together with a further twelve
full-time outside-funded staff, and two Visiting Industrial Professors:
Professor J. M. Taylor (Director, Hewlett-Packard Research Laboratories,
Bristol) and Professor I. M. Barron.  There are three Professors in the
Department: Professor M. H. Rogers, who is Head of Department, and Professors
J. W. Lloyd and D. H. D. Warren.

The Department has substantial research funding from ESPRIT, SERC, industry and
government.

The Department concentrates its research in three main areas:

Logic Programming
Parallel Computing
Machine Intelligence (including Computer Vision and Speech Processing)

although a number of other topics are also being pursued.

For this appointment, we are looking for a strong candidate in any area of
Computer Science, although preference will be given to candidates with research
interests in Parallel Computing or Machine Intelligence.   We are particularly
looking for candidates whose interests will broaden and complement our current
work in these areas.

Current work in Parallel Computing covers a range of areas, including parallel
logic programming systems and languages, memory organisation for multiprocessor
architectures, shared data models for transputer-based systems, and parallel
applications especially for engineering problems and computer graphics.  We are
seeking to broaden and strengthen this research.  Candidates with a strong
background in computer architecture would be particularly welcome.

Current work in Machine Intelligence centres mainly on Computer Vision and
Speech Processing.  One major project in Computer Vision is the development of
an autonomous road vehicle, based on real-time image analysis.  Other research
projects in Computer Vision include vehicle number plate decoding, aircraft
engine inspection, and visual flow monitoring. Current work on Speech
Processing within the Department concentrates on speech synthesis, but the
Faculty supports a Centre for Communications Research within which there is a
Speech Research Group incorporating researchers in most aspects of speech
technology, including speech recognition, speech coding, speech perception, and
the design of speech interfaces.  We are seeking candidates in any area of
Machine Intelligence  which would complement or enhance the current work.

The Department has a flourishing undergraduate and post-graduate teaching
programme and participates in degree programmes in the Engineering, Science and
Arts Faculties.   These programmes lead to B.Sc. degrees in Computer Science,
and Computer Science with Mathematics, a B.Eng. in Computer Systems
Engineering, a B.A. in Computer Science and a Modern Language, and M.Sc.
degrees in Computer Science, Foundations of Artificial Intelligence, and
Information Engineering.

The salary will be within the Lecturer Scale and the initial placement will
depend on age, qualifications and experience.

The closing date for applications is 27th November 1992.

Further particulars may be obtained from the Head of the Computer Science
Department (tel: 0272-303584; e-mail: barbara@uk.ac.bristol.compsci).

Subject: Research Fellow in Stereo Vision

The research positions given in my early notification have mostly been filled 
many thanks to all who expressed an interest. However there is one post still 
vacant,   

 Is there a really outstanding Post Doc out there to fill the post of
 RESEARCH FELLOW IN STEREO VISION ?

The project is funded by SERC/MTD and an industrial consortium and involves 
the development of an underwater vision system in which data from a pair of 
cameras is combined with 2D acoustic data. 

The candidate must have a (fully completed) PhD in the vision/image processing 
area or directly relevant industrial experience. They will preferably have a 
1st class honours and be able to start in the next couple of weeks. 

They will be responsible for collection and processing of the underwater vision
data and will be assisted by an RA who will collect the corresponding acoustic 
data. The project is initially for just 2 years so the applicant must be able 
to fire on all cylinders from day 1. There is not really any time available to 
read into the area.
 
The successful candidate will be expected to:
* Set up stereo cameras in test tank and collect data, dealing with any 
  problems which may arise and if necessary getting wet!
* Process the stereo data, 
* Report progress to industrialists on a regular basis, spending time at their 
  site if required,
* have a good knowledge of stereo vision algorithms and a sound grounding in 
  mathematical optimisation techniques, this is essential,
* assist in managing the RA in the collection of 2D acoustic data.

Am I asking too much? Well we can pay circa 18,000 pounds for the right person 
depending on age and experience. If you feel that you have a strong theoretical
vision background and are practical enough to `muck in' and collect the data 
then  send a full CV by email to

sm@uk.ac.strathclyde.eee.spd

			CALL FOR PAPERS

       		IEEE WORKSHOP ON QUALITATIVE VISION
        	Omni Park Central -- New York City
                  	Monday, June 14, 1993
								

WORKSHOP THEME:

Understanding, representing  and  incorporating  information on object
qualities  from  disparate  sources is key  to building  more  general
and  functional  computer  vision  systems.  Effective  representation
depends upon: 
   o object attributes captured by a representation or description
   o the interplay and synthesis of these qualities when multiple
     descriptions are available
   o the computational aspect of object qualities that participate in
     an effective representation
   o functional object qualities that guide visual reasoning.

The IEEE  Workshop  on  Qualitative  Vision  will focus on qualitative
descriptions and representations  of  the visual environment,  and new
algorithms for their computation.


WORKSHOP PROGRAM:

The  goal  of  the  IEEE Workshop on Qualitative Vision  is  to  bring
together  researchers  from  different  disciplines   for  the  active
discussion  of  the technical  issues   and   problems related  to the
development of qualitative  vision  techniques.  This one day Workshop
will be held in New York City  preceding  CVPR93. Sessions will be led
by an invited talk, and refereed  papers selected from those submitted
will be presented and published in a Workshop proceedings  distributed
by IEEE.

We invite the submission of papers on topics that include:
   o the synthesis  of  multiple visual qualities  (e.g.,  perceptual
     grouping, evidential reasoning over disparate sources)
   o the study of salient features or object qualities  (e.g.,  robust
     features which are invariant under image transformations)
   o efficient  and  innovative visual qualities  to support purposive
     operations (e.g., as exploited by active vision systems)
   o direct perception
   o discussion of differences between qualitative and  reconstructive
     approaches.
This list of topics  is not intended  to be exhaustive, and  inquiries
should be directed to the program committee.


PAPER SUBMISSION:

Papers should be limited to  20 double-space pages, including  figures
and  references.  Papers  should  include a  title page containing the
names and addresses of the authors, and an abstract of up to 200 words.
An  additional page titled  "Summary Page"   should  be included which
briefly describes the contribution of the paper. Five copies should be
received at the address below by Friday, December 9, 1992:

Conference on Understanding Images

Sponsored By

Pace University's 
School of Computer S
cience and Information Systems

To Be Held at:
Pace University
New York Ci
ty, New York
May 21-22,1993


Artists, designers, scientists, engineers and educators share the
problem of moving information from one mind to another.
Traditionally, they have used pictures, words, demonstrations, music
and dance to communicate imagery.  However, expressing complex notions
such as God and in finity or a seeminglywell defined concept such as a
flower can present challen ges which far exceed their technical
skills.

The explosive use of computers a s visualization and expression tools
has compounded this problem.  In hypermedi a, multimedia and virtual
reality systems vast amounts of information confront the observer or
participant.  Wading through a multitude of simultaneous images and
sounds in possibly unfamiliar representations, a confounded user asks:
What does it all mean?

Since image construction, transmission, reception, decip herment and
ultimate understanding are complex tasks strongly influenced by
physiology, education and culture; and since electronic media
radically amplify e ach processing step, then we, as electronic
communicators, must determine the f undamental paradigms for composing
imagery for understanding.

Therefore, the purpose of this conference is to bring together a
breadth of disciplines, including, but not limited to, the physical,
biological and computational sciences, technology, art, psychology,
philosophy and education, in order to define and discuss the issues
essential to image understanding within the computer graphic s
context.  To this end we seek proposals for individual presentations,
panel discussions, static displays, interactive environments,
performances and beyond.

Submissions:
Contributors are requested to submit a one page proposal by January 15,
1993.  Accepted presentations will be included in the proceedings.

o The Vision-21 Symposium

This symposium fosters speculative concepts in science, technology,
and advanced thinking. The event includes invited talks, panel
discussion, workshops, "poster" sessions, and an educational project
for Cleveland schools.

A key element of this symposium is to explore visions of applying
cyberspace, virtual reality, and interdisciplinary science to the
topics of space propulsion, power, and communication. Discussion
groups will be held with each keynote speaker. The scope of the
symposium goes beyond computing to explore the full spectrum of
science and engineering in the next millennium.

o Vision-21 Committee

Vision-21 is a group of scientists and engineers from NASA's Lewis
Research Center who seek to push the frontiers of aerospace technology
and science. We believe researchers need encouragement, time, and
cross-disciplinary communication to devise innovative concepts about
how man and craft will travel in air and space.We created an
interdisciplinary group called Vision-21 to provide 1) an environment
for the open exchange of ideas and 2) a process for exploring
futuristic aerospace concepts. Here researchers may conceive, nurture,
test, and develop promising ideas.

The committee has hosted one symposium ("Space Travel for the Next
Millennium") and led numerous discussions about long range aerospace
technology.

Technical Report

 Combining Shape from Shading and Stereo Using Human Vision Model


James Edwin Cryer, Ping-Sing Tsai and Mubarak Shah


CS-TR-92-25}



 { Abstract}

 Stereo algorithms suffer from the lack of
   local surface texture due to smoothness  of depth constraint,  or
   local miss-matches in disparity estimates.
   Thus, the stereo methods only provide a coarse depth map 
   which can be associated with a low
   pass image of the depth map. On the other hand,
   shape from shading algorithms produce better estimates of
   local surface areas, but some of them have problems with variable albedo and 
spherical surfaces.
   Thus, shape from shading
   methods produce better detailed depth information, and
   can be associated with the high pass image of the 
   depth map image.
In order to compute a better depth map,
we present a method for integrating  the high frequency
information from the shape from shading 
and the low frequency information from stereo.
Our method is motivated by the 
human vision system, and follows Hall and Hall's model.  
The proposed algorithm is very simple, takes about $.7$ seconds for 
a $128 \times 128$ image on a 
Sun SparcStation-1, is non-iterative, and  
does not use any thresholds. The results obtained with 
a variety of 
synthetic and real images are discussed.  
The quality of depth obtained by integrating shading and stereo is 
compared with the ground truth (range image) using average surface 
gradient error measure, and improvement ranging from 30\% to 50\% 
over stereo, and from 65\% to 98\% over shading is demonstrated.

Subject: IEEE PAMI and GRS collection -- Free to good home

I have a couple of boxes of IEEE journals that I'm never going to use again:

IEEE PAMI 1981 -- March 1992, plus a few issues in 1980. (One or two issues  
missing in there somewhere).

IEEE Geoscience and Remote Sensing -- 1981 through the present.

If the only way you'll take those is to also take my collection of Computing  
Surveys (about the same time period), I might be convinced...

I'd like to give these to some person or institution that will actually make  
use of them, rather than just throwing them out!

Make an offer, please (preferably by e-mail or phone 408.743.6318, not news!)
