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 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 Phill Everson ------------------------------------------------------------------------- SNAIL: Phill Everson, Dept Comp Sci, University of Bristol, England JANET: everson@uk.ac.bris.cs UUCP: ...mcvax!ukc!csisles!everson ARPANET: everson@cs.bris.ac.uk OR everson%uk.ac.bris.cs@nss.cs.ucl.ac.uk BITNET: everson%uk.ac.bris.cs@ukacrl.bitnet ------------------------------ Date: Mon, 27 Feb 1989 16:59-EST From: Takeo.Kanade@IUS3.IUS.CS.CMU.EDU Subject: Faculty Positions in Robotics 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. ------------------------------ End of VISION-LIST ********************
