Schultz) Subject: vector correlation Organization: 3M - St. Paul, MN 55144-1000 US A friend gave me a copy of an article from the Jan 1990 (p 138-9) Photonics Spectra on "Vector Correlation" which was the first I have heard of the concept of vector correlation. As I understand what the author was talking about, you use a high-pass filter such as a Sobel to determine edge magnitude and gradient (the article only discussed 4 angles vs. Sobel's 8). The correlation for object location can then be done much more robustly wrt lighting variations by correlating the 4 (or 8 for Sobel?) images for each direction vector and summing the resulting correlation images. The advantages of this approach would seem to be: 1. insensivity to light level even as compared to normalized correlation 2. greater location precision since the object location is completely determined by its edge location(s) The disadvantage is the computational complexity - what was one correlation has suddenly become 4 (or 8 in the case of Sobel?). My questions: Why vector correlation? Seems to me this is just a fancy name for object edge correlation. Does anyone know have any references for this technique? Possibly under a different name? The author was from Applied Intelligent Systems Inc. and neglected to include any references :-). Anyone have any experience with this technique? Any code they would be willing to share? As a final note, I think this is what Intelledex uses internally to their "turn-key" vision system and they do get 1/10 pixel location precision under a lot of variable and/or poor lighting conditions.

Johnston Subject: Additions to List of IP Source Code Packages In a recent posting to the vision-list I listed packages of image processing source code, available in the public domain or for a one-time license. I inadvertently left out the HIPS software package developed by Michael Landy. My apologies to Professor Landy. Here is the information on HIPS. In addition I received information about a package called XVision available from the University of New Mexico. Once again, I welcome any additions or corrections to this list. Scott E. Johnston johnston@ads.com Advanced Decision Systems, Inc. Mountain View, CA 94043 ======================================================================== HIPS Contact: SharpImage Software P.O. Box 373 Prince St. Station NY, NY 10012 Michael Landy (212) 998-7857 landy@nyu.nyu.edu Description: HIPS consists of general UNIX pipes that implement image processing operators. They can be chained together to implement more complex operators. Each image stores history of transformations applied. HIPS is available, along with source code, for a $3000 one-time license fee. HIPS supports the following: - simple image transformations - filtering - convolution - Fourier and other transforms - edge detection and line drawing manipulation - image compression and transmission - noise generation - image pyramids - image statistics - library of convolution masks - 150 programs in all ======================================================================== XVision Contact: John Rasure Dept. of EECE University of New Mexico Albuquerque NM 87131 505-277-1351 rasure@bullwinkle.unm.edu XVision is a C-based system developed at the University of New Mexico. It includes: 1) an image processing library of 150 algorithms from early processing to classification and shape analysis 2) a graphical form/menu interface and a command line interface 3) a visual language for configuring complex image processing pipelines 4) an extensive 2d and 3d plotting capability 5) an interactive image analysis capability 6) code generators for generating the command line user interface and the X windows user interface C code. The system runs on most UNIX systems and they have a limited number of licenses that they can give at no cost. ------------------------------ Date: Wed, 14 Mar 90 13:24:11 +0800 From: les@wacsvax.cs.uwa.oz.au (Les Kitchen) Subject: Australian AI Conference CALL FOR PAPERS 4th Australian Joint Conference on Artificial Intelligence AI'90 21-23 November, 1990 Hyatt Regency, Perth, Western Australia Everyday AI - New Tools for Society This conference is a major regional forum for the presentation of recent research on the theory and practical applications of Artificial Intelligence. It acts as a catalyst to stimulate further research and cooperation in this important area within the Australasia and Indian-Pacific region. The theme of this year's conference aims to encourage and promote AI techniques and tools for solving everyday problems. Topics Include (but not limited to): * Logic and Reasoning * Knowledge Representation and Acquisition * Machine Learning * Artificial Neural Networks ====> * Computer Vision and Robotics * Natural Language and Speech Recognition * Expert Systems and development tools * Applied AI in Civil, Electrical, Electronic, and Mechanical Engineering * Knowledge Engineering in Business Applications * Applications in Government and Mining Criteria for acceptance This conference welcomes high quality papers which have a significant contribution to the theory or practice of A.I. Papers in the application areas will be judged by their novelty in the application, its formulation, application of new A.I. techniques, and the success of the application project. Requirement for submission Authors must submit four copies of their full papers to AI'90 Programme Committee by 11th May 1990. Submissions after the deadline may be returned without being opened. Notification of acceptance and format of the camera ready copy will be posted by the 27th July 1990. The camera ready final paper will be due on 24th August 1990. Paper Format for Review The paper should be about 5000 words in length. It should be at least one and a half spacing and clearly legible. Authors should try to limit their paper to not more than 15 pages not including diagrams. Each paper must include a title, an abstract about 100 words, but no other identifying marks. The abstract of 100 words with the title, authors names, and correspondence address should accompany the submission on a separate page.

Please direct responses to the poster of this message. phil... ] The broad distribution of this proposal should give some idea as to why I consider the creation of this group appropriate. The subject of robotics can draw on information from all of these groups and more, yet none is particularly appropriate to it. There is no one group I could go to with a specific robotics problem with a high probability of finding anyone who even has the same problem, let alone a solution. Rather than broadcast such questions to the net, I'd like to see a dedicated group formed. I therefore propose a new group: Name: comp.robotics Moderation: Unmoderated Charter: The discussion and exchange of information on the practical aspects of real-world robots and their applications -- industrial, personal and experimental. I put in the "real-world" qualification deliberately to exclude discussions of positronic brains, R2D2 and who, if anyone, was really inside Robbie in "Forbidden Planet." I suggest that Asimov's laws are also best left to a more philosophically or socially oriented group. For those interested in leading edge research, AI, machine vision, etc. a sci.robotics group might be more appropriate and can also be discussed at this time. I don't think the two groups are mutually exclusive. (i.e.: Creation of one doesn't necessarily remove the need for the other). Follow-ups are directed to news.groups The Polymath (aka: Jerry Hollombe, hollombe@ttidca.tti.com) Illegitimis non Citicorp(+)TTI Carborundum 3100 Ocean Park Blvd. (213) 450-9111, x2483 Santa Monica, CA 90405 {csun | philabs | psivax}!ttidca!hollombe ------------------------------ End of VISION-LIST ********************
