Subject:    PD Image Processing Software for Suns
From: phill%MED-IMAGE.COMPSCI.BRISTOL.AC.UK@CUNYVM.CUNY.EDU

     This is to introduce a toolkit of image processing pro-
grams,  collectively  called  the ALV toolkit for historical
reasons, written by Phill Everson <everson@uk.ac.bris.cs> in
the  Computer  Science  Dept.  of Bristol University, United
Kingdom.

     The toolkit is designed to aid image processing work on
Sun  workstations.  It is intended to be easy to use, though
not restrictive  to  experienced  users,  user-configurable,
extensible  and flexible.  For example the toolkit will work
on both black and  white  and  colour  workstations  and  in
either  case  will  transparently,  to  the user, display an
image to the best of its ability on the screen.

     The  toolkit  has recently  been  rewritten  to use the
standard Sun rasterfile format  to store its images allowing
multiple depth  images to be processed by the  same  toolkit
and easy migration of data between packages.

*** All people currently on the alv-users mailing list  will
receive a copy of the new toolkit in the next couple of days.

     The toolkit is made up of  a  number  of  tools.  These
include  programs  to  display  an  image  on the screen, to
display a histogram, to perform histogram  equalisation,  to
threshold,  to  print  an  image on an Apple Laserwriter, to
invert an image and  to  convolve  an  image  with  a  user-
supplied  linear  filter.  Currently, there are 27 such pro-
grams.

     The toolkit was initially written to fulfill a need  at
Bristol  University  for  a  single coherent set of tools to
support basic image processing research on a variety of pro-
jects.  We  had  found  that each user or group of users was
writing their own copy of programs  to  do  similar  things,
like  displaying  an  image  on  the screen, and more impor-
tantly, in an enviroment were disk  space  is  always  at  a
premium,  was  each  keeping  separate copies of these often
large programs.

     Using a coherent set of tools with  a  consistent  file
format  has substantially increased cross-project communica-
tion and in addition has provided a higher starting point on
the  learning  curve  for  novice Sun-Users/Imagers. We have
found that users generally use the core tools as a basis and
are then able to concentrate their work in their own area of
interest.

     The ALV toolkit comes complete with a 40-50 page manual
online which can easily be dumped to a laserwriter to  prov-
ide and impressive reference for a Public Domain Program.

The toolkit is currently distributed via email.
Contact <alv-users-request@uk.ac.bris.cs> to request a copy.

The following are the commands currently in the toolkit:

     array2ras - convert array to raster
     blend - blend two rasters together
     box - box a raster
     convert - convert textual raster to raster
     convolve - convolve a raster with a linear filter
     dither - convert 8 bit raster to 1 bit using dither matrix
     dsp  - display a raster on screen
     equalise - equalise a raster
     ffill - flood fill a raster
     halftone - convert an 8 bit raster to  1  bit  using  bitmap
     font
     hist - display histogram of raster
     im2ras - convert old ALV format to raster
     invert - invert the pixels in a raster
     ras2array - convert raster to array
     ras2im - convert raster to old ALV format
     ras2lw - output a raster on a Laserwriter
     rasinfo - print raster udimensions and depth
     rasrange - range a raster's greylevels
     rasregion - clip a raster to a region
     rasscale - scale a raster's size by a scaling-factor
     rasthresh - threshold raster
     rasval - print pixel values of raster
     scr2ras - interactive screendump to raster
     transform - shear or rotate a raster
     winlev - convert N bit deep raster to 8 bits deep
     winlev8  -  interactively  change  window  and  level  of  a
     displayed raster

			 Faculty Positions in Robotics

		          Carnegie Mellon University
		            Robotics Ph.D. Program


Applications are invited for tenure-track faculty positions in the Robotics
Ph.D. Program at Carnegie Mellon University.  The program is
interdisciplinary with participation from the Robotics Institute, School of
Computer Science, Carnegie Institute of Technology (the engineering
college), and Graduate School of Industrial Administration.  Appointees are
expected to play major roles in education and research in the program.  The
appointments may be made at either assistant, associate, or full professor
levels, and in general will be joint positions between the Robotics
Institute and an academic department or school, depending on the
qualifications and backgrounds of the applicants.  If so desired, a non-
tenure-track research faculty position at the Robotics Institute can also be
considered.

Applicants for tenured positions must have strong records of achievements in
research and education in robotics and have demonstrated leadership in
formulating and performing advanced research projects.  Applicants for
junior tenure-track positions must have a Ph.D. in a related discipline and
have demonstrated competence in one or several areas of Robotics research
together with potential for excellent teaching.

Outstanding candidates in all areas of Robotics are invited, including, but
not limited to, mechanism, manipulation, control, locomotion, vision,
design, planning, knowledge-based systems, simulation, graphics,
micro-electronics, parallel computing, manufacturing, and management. 

Applicants should send their applications with curriculum vitae and names of
at least four references to:  Professor Takeo Kanade, Director of the
Robotics Ph.D. Program, The Robotics Institute, Carnegie Mellon University,
Pittsburgh, PA 15213.

Carnegie Mellon is an Equal Opportunity/Affirmative  Action employer.
