Principal investi- gators on the project are Dr. Robert Fisher and Dr. John Hallam. The project investigates the use of laser-stripe based range data to identify and locate parts as they pass down a conveyor belt. The vision research to be undertaken includes topics in: surface patch extraction from range data, surface patch clustering, geometric object modeling, model matching, geometric reasoning. The project builds on substantial existing research. The first researcher will be expected to take a leading role in the day-to-day project management of this and a related project (5 research staff total) as well as undertake scientific research. Applicants for this post should have a PhD (or compar- able experience) in an appropriate area, such as computer vision, artificial intelligence, computer science or mathematics. The second researcher will be more involved in software implemen- tation and testing, but will be expected to undertake some origi- nal research. Applicants should have at least a BSc in an ap- propriate area. Both applicants should have experience with the C programming language. Applicants with experience in computer vision, the UNIX operating system, the C++ language, or the Prolog language would be preferred. Both posts are funded for a period of three years starting No- vember 1, 1989. The salaries will be in the range 10458-16665 (AR1a) for the first post and 9816-12879 (AR1b/a) for the second post, with placement according to age, experience and qualifica- tions. Applications should include a curriculum vitae (3 copies) and the names and addresses of two referees, and should be sent to the Personnel Department, University of Edinburgh, 63 South Bridge, Edinburgh, EH1 1LS by September 6, 1989, from whom further par- ticulars can be obtained. In your application letter, please quote reference number 1651, and indicate for which of the two posts you are applying. ------------------------------ Date: Tue, 8 Aug 89 10:46:06 CST From: George Travan Subject: least squares fitting. i interested in obtaining some pointers to C code which will do a least squares fit on 2D and 3D shapes consisting of a number of discrete points. also, are there any good reference sources to 2d or 3D shape analysis. im particularly interested in mirror imaging and shape difference quantification thanx -GeO George Travan University of Adelaide AUSTRALIA ACSnet: gtravan@sirius.ua.oz ------------------------------ Date: 10 Aug 89 17:15:48 GMT From: hplabs!tripathy@hpscdc.hp.com (Aurobindo Tripathy) Subject: Friend looking for a image processing job in a stable company Organization: Hewlett-Packard, Santa Clara Div. For all you folks doing work in computer vision in the industry, I have a question! ...Why is this group so quiet ? There are never any [ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Good question. phil...] issues discussed here. Does every body work for the military ? ... Let me make a start. I have a freind looking for a job in the image processing area with a solid background to image processing hardware design and excellent understanding of image processing algorithms. He has about six years experience in the industry. Can any one recommend a stable :-) imaging, image processing company. aurobindo ------------------------------ Date: Thu, 10 Aug 89 15:30:03 pdt From: maurinco@iris.ucdavis.edu (Eric Maurincomme) Subject: Grayscale Morphology software About 3 weeks ago, I posted a query about any existing public domain morphology software. Firstly, I would like to thank all the people who replied to my query, by giving me advices or answers. Secondly, it appears that there is no public domain software for morphology around. I was principally interested in grayscale operations. Most of the replies I got were about general purpose software packages, in which a few morphological operations are implemented. I will try to give a brief compilation of the answers I got : At the University of Washington, Linda Shapiro and her colleagues use a a software package called GIPSY, that has about 400 commands, including morphology, and that runs under UNIX. This is a general purpose package that runs slowly but covers a lot of ground. The morphology is just one command that can do dilations, erosions, openings and closings with the user defining his own structuring element by means of entering a mask. Finally, it costs something like $5000. A few people at the University of Maryland working with Rosenfeld refered me to a few existing software packages. There is one written by Serra's team. It's called MORPHOLOG, or its new version which is called VISILOG; the latter one is on sale by a French company (NOESIS) for about $8000. If you want more information on MORPHOLOG, you may want to contact La"y at the School of Mines in Paris. The software works on an hexagonal grid, and a description of it can be found in : B. La"y, Descriptors of the programs of the Software Package Morpholog, Ecole des Mines, Paris. They also refered me to an Image Processing Software package called IPS, that has been created by a French lab in Grenoble, and they have quite a few both binary and grayscale morphological operations running on it. It's been developed on Appolo workstations, and is on sale for about 40000 French Francs, which is about $6000. Apparently the same software has been implemented to work on a PC, and is commercialized by the society Thomson-Titn, and is called SAMBA. If you want more information on IPS, you may want to contact Guy Bourrel at bourrel@imag.imag.fr who is implied in the development of this software. His address is Guy Bourrel Equipe de Reconnaissance des Formes et de Microscopie Quantitative Universite Joseph Fourier CERMO BP 53X 38041 Grenoble cedex France tel 76-51-48-13 Another general purpose image processing software package which includes some of the basic morphology stuff is called HIPS, and is commercialized by Mike Landy at Sharpimage Software in New York. Finally, a word of comment to tell the netters why we are looking for grayscale morphology tools. We have implemented some binary morphology in our Image Processing lab (now called CIPIC (Center for Image Processing and Integrated Computing), which is a campus-wide research unit). It runs on an image processing board IP8500, mounted on a VAX. It does all kind of opening/closing dilation/erosion, and can be used for skeletonization, etc.... The next step is to implement gray scale morphology. I am working with Professor Ralph Algazi (algazi@iris.ucdavis.edu), and we wanted to know what the state-of-the-art is in this area.....
